Poly(vinylidene fluoride) (PVDF) resin is highly inert and difficult to functionalize for crosslinking, but most commercial PVDF-based coatings use the PVDF resin in combination with other compatible resins, such as acrylics, allowing for the possibility of some degree of crosslinking in the polymer alloy binder. We will present results from recent new investigations looking at several non-isocyanate (NISO) routes to achieve crosslinked PVDF-based coatings. These include both external non-isocyanate crosslinkers, and a radiation-curing approach. Both approaches are effective ways to boost solvent and dirt pickup resistance, compared to purely thermoplastic systems. At the same time, crosslinked systems of this type tend to maintain good flexibility, and exhibit excellent weatherability like the thermoplastic systems.

Traditional oxidative cured systems have relied on conventional driers such as Cobalt and Manganese for decades. Although these surface driers are efficient, there are many drawbacks that arise. These systems may encounter yellowing, discoloration, marginal dry time improvement, wrinkling at high film thicknesses, and issues with regulatory demands such as APEO-free and regional compliance. This presentation will discuss a novel drier technology that not only improves dry time, yellowing, and discoloration but may also yield surface and through dry in one drier. Today’s next generation oxidatively cured systems demand novel drier technology and this Cobalt-free molecule delivers.

Additives play critical roles in waterborne coatings formulations, including formulation stability, application properties, appearance, and coating performance. Low-shear thickeners that deliver excellent anti-settling and sag resistance without significantly impacting the mid-high shear viscosity are desirable for many coatings applications. It is desirable to have shear-thinning rheology modifiers in order to have high film build in spray applied coating. Associative thickeners that can be post-added in the formulation for viscosity adjustment is often preferred by formulators due to their ease of use and better performance compared to inorganic thickeners and hydroxyethyl cellulose. In addition, inorganic and cellulosic thickeners often bring other negative impacts to the final coating properties, such as gloss reduction. On the other hand, industrial waterborne coating formulations often contain high amounts of solvents and/or amine hardeners, which impact the thickening efficiency and rheology profiles of the associative thickeners. The design of associative thickeners, especially the hydrophobe type, is critical for the association between the thickeners and binders. We will discuss promising research efforts in developing robust low-shear associative thickeners for waterborne industrial coatings that might contain high level of solvents or hardeners.

Water-based interior architectural paints are replacing solvent-based formulations as consumers are shifting towards environmental-friendly, low VOC products. The flow properties that govern the application of water-based paints are achieved using water-soluble rheology modifiers also known as thickeners. One of the desirable properties for interior paints is improved stain resistance to hydrophilic and hydrophobic stains. Stain-resistant paints require a combination of tailored polymer dispersions and balanced paint formulations. The Paint industry have internal test methods to assess the stain resistance to common household stains which are based on a subjective visual rating scale. This study details multidisciplinary approaches to understand the stain resistant property of coatings. Molecular modeling has been used to simulate stain interaction with the paint surface and new methods based on Atomic Force Microscopy (AFM) have been developed to study the coating surface chemistry. Additionally, an in-situ stain testing method that measures stain adsorption and de-sorption using a Quartz-crystal microbalance sensor will also be discussed. The objective is to understand the overall mechanism of stain interaction with paints that will help in formulating and fine-tuning improved stain-resistant coatings.

Usually, low volatile organic compound (VOC) waterborne paints generate dry paint films with lower hardness and dirt pick-up resistance due to the usage of high boiling point coalescents. In this work, the effect of low VOC coalescents on latex film formation, hardness evolution, accelerated dirt pick-up resistance, and surfactant leaching of waterborne paints will be explored. AFM (Atomic force microscopy) images of styrene-acrylic and pure acrylic latexes containing 4 wt% of different coalescents show that low VOC coalescents generated films that were more coalesced and smoother than standard high VOC coalescent. A new low VOC coalescent generated semi-gloss paints with higher hardness evolution and better dirt pick-up resistance than commercial low VOC coalescents and similar to standard high VOC coalescent. Moreover, flat paints formulated with this low VOC coalescent dried at harsh conditions presented lower surfactant leaching in comparison to the ones formulated with standard high VOC coalescent. These results suggest that there is a correlation between surfactant leaching and film formation assessed through AFM.

Wood and Wood Coatings: A Brief History. Wood and wood products have been part of mankind’s life since before recorded time. Man has learned how to use wood to help him in his life. He also found out wood doesn’t last forever, so he devised methods to help preserve and protect these wood products. This Presentation is about different types of wood and wood products and different types of coatings used to protect them. Types of wood products that man has invented include furniture, means of transportation and dwellings. The kinds of coatings covered here are mainly older finishes like lacquers and varnishes and the chemistry involved with these coatings. 21st Century Coating Challenges. A number of challenges face the coating industry in the 21st century. Included in this group are development of non-oil based sustainable ingredients that allow for more durable, energy saving and healthier coatings both to manufacturer and apply. Cool coatings are one product-type in the group being actively researched, developed and manufactured. This talk is about cool coatings and how new near infrared reflective and transparent pigments are finding their way into the marketplace.

Thermosetting polyester-based coatings crosslinked with melamine, ubiquitous in coil coatings, experience large deformations when formed to produce white goods or architectural cladding. The effects of increasing the crosslinker content on the thermo-mechanical and tensile properties of free films have been investigated. The DSC glass transition temperature (Tg) plateaus after the stoichiometric point; however, the DMA tan(δ) Tg increases from 49 ± 1 °C to 72 ± 1 °C, a result of the dynamic modulus changing with temperature. The crosslink density inferred from the storage modulus increases as expected. The effects of temperature on the tensile properties have been normalised using DSC Tg. Young’s modulus increases with crosslinker content above Tg, but below Tg the effects are negligible. The apparent yield strength increases with crosslinker content. Increasing the crosslinker content decreases the strain to failure, yet this effect is negligible at low temperatures. The effects of pigmentation have also been considered. The TiO2 pigment increases the modulus of the coatings, but the strain to failure is unchanged. These results are used to predict the brittle to ductile transitions of the coatings and suitable forming conditions for the coated steel. These predictions have been validated by Erichsen cupping tests.

Matte and gloss are qualitative impressions recognized by our senses, which can be quantified by instruments such as a glossmeter. Wall paints, furniture finishes, and decorative finishes are some matte surfaces we encounter in our daily routines. Consideration for matting a surface may be advantageous for multiple reasons such as: hiding surface imperfections, aesthetics etc. Due to regulatory concerns and long-term availability of existing matting agents; there exists an imperative need to seek alternative matting agents. Understanding matting agents, their functionality and their applications as they pertain to coatings will be discussed. Presented in detail will be alternative solutions for matting agents based on calcium carbonate and their benefits for coating applications.

Azelate polyols provide unique physical properties and performance benefits to subsequent polyurethane polymers that incorporate them. Potential benefits expected from novel renewable azelate polyols intended for use in coating or elastomeric applications include both relatively high renewable carbon content and improved performance. A new series of polyols based upon azelaic acid (a C9 diacid) involving a variety of possible partner glycols has been developed and have been described within this work. These polyols have been characterized for their chemical attributes as well as their rheological (lower relative viscosities) and thermal properties (lower relative glass transitions). Model polyurethane coatings and elastomers produced from them have been created and the results of these polymers are also represented herein. These polyols offer several performance benefits of interest to a final user resulting from structure-property considerations such as the odd-even effect, the aliphatic nature of their structures, and the consequent polarity contribution of the carbonyl groups that define the polyester polyol composition. One such benefit observed is a diverse hydrophobic characteristic permitting a broader choice within the spectrum of better hydrolytic stability to hydrophobic behavior with added traits including better chemical resistances within coatings and broader chemical solubilities as quantified by Hanson Solubility Parameters.

The innovative nonionic emulsifier are based on a linear, fully saturated synthetic Ziegler alcohol with a chain length of C20 to C30 and up to 150 moles of EO. Examples will be presented to demonstrate the excellent performance of these ethoxylates as emulsifiers for finely dispersed Fischer-Tropsch hard wax emulsions as well as for resin free wax dispersions. These new emulsifiers enable to make and carbon black dispersions with high PVC, increased color acceptance and shear stable viscosities. Those wax emulsions can be used for different applications, such as wood coatings, ink formulations and for increased water resistance in industrial coatings. Emulsifiers based on this new alcohols with a molecular weight up to 6,000 g/mole are outstanding nonionic grinding additives for hydrophobic pigments such as non-modified carbon black, iron oxide or uncoated titanium dioxide. Furthermore this emulsifier group shows exceptional performance for emulsifying silicon oils, resins and bitumen, while also performing a de-inking function when added to the flotation process

Complex systems exhibit non-trivial emergent and self-organizing behaviors. Examples of complex systems include the rainforest, insect colonies, the immune system, the stock market, and the World Wide Web. These systems display hierarchical organization, which results in emergent properties which are not characteristic of the individual system components. A familiar example of emergence is the property of wetness that a large number of water molecules collectively displays; no single water molecule exhibits wetness, but water clearly gets things wet. The relationship between a coating formulation and its end-use properties may be represented using a complexity-based approach, where formulation components form hierarchical relationships which ultimately determine the emergent end-use properties of the coating. In this presentation, the complexity of coating formulations will be explored, with the objective of determining how best to consider coating formulations in the design and control of new products having highly specific end-use properties.

Today’s challenges for coatings, adhesives and materials industries are clearly environment oriented. Coatings particularly is one field in which high performance is required since the function of a coating, outside of the aesthetics, is mainly to protect the substrate it is applied on. Polyurethane coatings, especially two components systems, are very appreciated for their outstanding performances, especially durability and outdoor weatherability. Polyisocyanates as building blocks for polyurethane and polyurea technology have clearly their role to play in this trend.

Two routes will be exposed in this presentation: one dealing with water based system, the other one proposing original solutions for solvent borne low VOC system, more specifically for polyurea products.

When environmental preoccupations started to be at the forefront, 2K polyurethane waterborne coatings became naturally a route to follow, especially to reduce Volatile Organic Compounds (VOC) in the formulations. The challenge was above all to design waterborne formulations containing polyisocyanates which would be stable, regarding the reaction with water. Such a formulation should provide enough time to enable application and film formation with good end properties. We will demonstrate our hydrophilic polyisocyanates can advantageously be used to overcome these challenges.

Another route to face this environmental challenge is to drastically reduce the VOC content of the solvent borne solution. Poly aspartic based systems are more and more used in that scope. Thanks to their chemical structure they can be used in high solid formulations and their reactivity make them a very good candidate to reduce curing time thus allowing energy savings. Nevertheless this high reactivity goes with some handling difficulties (short pot life) and some mechanical drawbacks in some applications (brittleness). Using some new low Tg isocyanate or some original biobased building block could be solutions to overcome these points.

Low VOC coalescents that are used in emulsion coatings and remain in the cured film, impart properties to the coating that may not be desirable, particularly on the hardness of the dried coating. This presentation demonstrates a Low VOC coalescent that shows high efficiency, enabling it to be used at reduced loading, which reduces the negative impact on film hardness. As an additional benefit, the coalescent is compatible across a large range of polymer types, allowing it to be used in many types of coatings where the benefits of the coalescent can be utilized, and reduce the need to inventory multiple Low VOC coalescents.

The use of a suitable dispersant is imperative to achieve good stability and color properties for dispersed pigments in waterborne paint systems. Dispersing solid particles using either electrostatic repulsive or steric hindrance mechanisms can be achieved by combining polyelectrolyte dispersants and traditional non-ionic surfactants. However, improved stability and color development can be accomplished using the new high molecular weight dispersant discussed in this paper. It is shown that the new polymeric dispersant is suitable for low VOC-free and APE free pigment dispersions for industrial and ink applications. Compared to traditional polymeric types the properties are enhanced. Our new dispersant provides excellent color strength development in conjunction with a variety of pigments, low viscosity at high pigment loading, improved long term stability and high gloss development.

The construction industry uses dry mortars – amongst many others – for tiling adhesives, self-levelling flooring compounds, wall renders and joint fillers. With a growing demand for housing, office space and better infrastructure speed and high productivity in such applications is essential. As it happens, the key ingredient to drive fast setting dry mortar products – Lithium Carbonate – is also in high demand for re-chargeable batteries used for example in electric cars and thus is getting tight in supply and increasing in price. Technical experts at IMCD Coatings & Construction have delivered an innovation that means two booming markets no longer have to compete for the same resource. This paper presents a solution based on non-scarce resources that matches the acceleration of Lithium compounds in cementitious dry mortars. What’s more, it delivers extended workability times at almost equal adhesion-, flexural- and compressive strength.

Current corrosion inhibitors for coatings can be summed up as zinc pigments, phosphates or chromates for protection of steel. These materials are potentially damaging to the environment and in some cases to human health as well. Chromates in particular are being phased out in many countries as the health concerns associated with exposure to Cr(VI) are deemed to be significant. As legislation begins to turn, and increased scrutiny is placed on manufacturers, the options for reducing heavy metal levels in coatings, and enabling metal free coatings begin to offer greater value to formulators, applicators and asset owners.  Encapsulation technologies with controlled release capabilities represent a novel and innovative approach for the coatings industry. The use of matrix style encapsulation in silica and hybrid silica, as opposed to core shell technologies, allows for the compatibilisation of a broad range of effective organic and organometallic corrosion inhibitors that would not normally be compatible with paint chemistries.  This paper will demonstrate some of the advantages of using a matrix-based encapsulation technology to provide improved corrosion protection in coatings and paints. The protection of both aluminium and steel substrates will be discussed and compared against standard corrosion pigments using electrochemical and accelerated ageing techniques.

Emissions of volatile organic compounds (VOCs) from coatings have been regulated in the US for decades, yet there is still no unified definition of what constitutes a VOC in coatings. The US EPA bases its definition on whether or not an organic compound participates in atmospheric photochemical reactions. However, EPA Method 24, for experimentally determining VOCs in coatings, is based on what remains in a coating after heating for one hour at 110oC (the “solids” content). Direct methods based on gas chromatographic analysis can identify volatile compounds in a coating matrix given a reference definition based on boiling point or retention time. But relative retention times from gas chromatography do not correlate perfectly with boiling point or volatility. What if compounds might partially remain in coatings after application only to be emitted later to the atmosphere? Almost all methods treat all VOCs equally (same mass of ozone produced for same mass of compound) although it is well known that the ozone producing capability of organic compounds varies enormously. Data from a variety of test methods on recent samples will be compared and used to suggest possible approaches to resolving this problem.

Formulators continue to be challenged by legislative demands to reduce emissions, while improving performance and durability of topcoats. Silicone aliphatic polyester resins combine the high chemical and weathering resistance of silicone polymers with the flexibility and adhesion of polyesters. Once cross-linked, these polymers can be formulated to give topcoats with improved corrosion, resistance, impact and scratch resistance. These binders can be used alone or as co-binders in combination with other established acrylic or polyester binders. This paper will review the properties of two novel silicone hybrid resins and their use in topcoats for automotive and vehicles.

Coating and ink manufacturers are always looking for new technologies that will significantly reduce their environmental footprint. Water-based coatings with no or considerably reduced solvent content as well as 100% solids systems, including energy cured applications, are obvious product design choices. However, these approaches create challenges in efficient pigment dispersion and stabilization. Carbon black remains one of the most important pigments in coatings and inks due to the strong link between quality of dispersion and the coloristic properties of the resultant coating. Dispersion stability is influenced by the pigment’s structure, surface area and surface chemistry. Studying the dispersions of different carbon blacks in several coating systems, enabled us to optimise our single and multi-anchor dispersants for use in both UV and Water Based systems. We have demonstrated that the structure of our dispersants enables very efficient milling, reducing overall energy requirements. Our anchoring chemistry helps produce exceptionally stable dispersions without the need for added wetting agents. The benefits obtained from these developments can also be applied to design optimized dispersants for organic and inorganic pigments. In this presentation we show how optimizing dispersant anchor groups enables exceptional coloristic performance and dispersion stability. Combinations of novel anchors with appropriate stabilizing chains extends this to a wide range of coatings and inks applications, particularly those formulated for environmental compliance.

There is growing interest to design smart coatings with functionality beyond their traditional use of decorating and protecting surfaces. This work explores the technical feasibility of using enzymes as a functional ingredient in water-based coating systems. Initially, a model enzyme (Cellulase) was used to study enzyme activity in the wet and dry film stage, determine enzyme localization, and to understand the impacts of different formulation parameters including fillers types, PVC, and VOC levels on enzyme behavior. We successfully developed a variety of new analytical methods to enable direct analysis of enzyme activity and localization in dispersions and coatings. Enzymes fully retained their activity in the wet stage of aqueous-based coating dispersions and remained highly active following extraction from dry films. The in-film activity of the enzyme is lower than that of soluble enzymes in solution; however, formulation ingredients had significant impacts on in-film enzyme activity. The enzymes were heterogeneously distributed in dry coating films, exhibiting a concentration gradient towards the surface and enrichment around filler particles. Further, the enzymes were able to diffuse within and out of the film into liquid surroundings, while the diffusion rate of enzymes were significantly affected by the PVC of the film. Finally, we show that multiple other classes of enzymes remain active in commercially representative paint formulations, and that diffusion rates of enzymes within and out of the film can be influenced by formulation ingredients.

The popularity of waterborne (WB) coatings has increased primarily driven by the desire to reduce the presence of volatile organic compounds (VOCs) and their impact on human health and the environment. Today’s WB epoxy coatings maintain most of the performance strengths of traditional high VOC solvent-borne coatings and high solids system making them suitable for commercial and industrial use. This paper describes some of Olin’s work in developing WB epoxy floor coatings. We have developed high film build self leveling coatings and satin gloss roller coatings. Various performance aspects of WB epoxy floor coatings including performance properties, starting formulations, and application procedures will be described.

Waterborne coatings dominate the architectural coatings segment.   There is a huge demand for balanced performance within the residential repaint markets, which is reflected in the claims paint companies highlight on their products.  Stain resistance, durability, and one-coat hide are just a few that are commonly touted. The first portion of this presentation will provide details from a benchmark study on commercial products. The second portion will outline the polymer development work that we have carried out to achieve a balance of coatings performance. Particular focus will be placed on the impact of polymer and surfactant composition on paint performance.  In addition, the impact of the paint formulation will be discussed.

High temperature resistant coatings are essential to protecting and maintaining longevity of metal substrates and are utilized in several industries, including oil and gas, automotive (exhaust pipes, engines), household appliances (stoves, fireplace chimneys), and many others.  With demanding performance requirements, formulators often utilize proven, superior performing solventborne technologies; however, the increase in environmental, health and safety, and regulatory restrictions has excited an interest in cleaner and regulatory compliant solutions.  Formulating away from solventborne, to waterborne coatings, without sacrificing performance, is gaining increased attention in the high temperature resistant and protective coating market segments. High temperature performance requires highly crosslinked matrices, whose architecture must remain stable when exposed to heat, exceeding 600°C in some applications. In comparison to hydrocarbon-based binders that degrade when exposed to high temperatures, silicone resins have a more robust structure capable of maintaining film integrity.  Most silicone resins used for high temperature resistance require oven cure to undergo complete condensation and achieve cured film properties, in-turn raising energy and capital costs.  Dow continues to drive cleaner, innovative solutions to address unmet market needs across the globe, and the high temperature coatings market is no exception; this presentation will illustrate progress in the development of heat resistant, room temperature curable silicone resin emulsions.

Boosting color strength is on the forefront of coatings formulators and manufacturers minds. However, for many systems improving color performance is a difficult task. Whether it is a ready-made dispersion or a fully formulated system, large adjustments to the formula can be unfeasible due to manufacturing, VOC, and consumer restraints. Today’s technology allows for post addition of an additive to improve color acceptance, color strength, and quality of the pigmented system. A simple addition of a color booster or compatibilizer to the base will result in a stronger, cleaner, and more chromatic color. Benefits are evident in tints with difficult organic pigments and carbon blacks. An additional benefit is a reduction or elimination of color rub-out and improved compatibility of universal waterborne systems used in solvent-based bases. This presentation will provide additional data, visuals, and tools that aid in solving color acceptance issues and create more flexibility in product development.

Recent trends in the chemical industry have been towards consolidation, less upstream flexibility, more frequent and unexpected raw material shortages, more constrained carrier capacity, and increased demand volatility. The consequences of such forces on planning and operating a reliable supply chain can no longer be affordably mitigated through an inventory–only approach.

Rather, coping with such pressures has led to innovation in relationships between suppliers, co-suppliers, and downstream customers. Such innovation can take many forms: not only in better product technology and resultant formulations, but also increased intimacy between companies via relationships across multiple functions and hierarchical levels. Operationally this means evolving from a classical buy-sell relationship across a firewall towards collaborative problem-solving by knowledgeable experts in real time in the right operational roles when life does not materialize as anticipated.

A case study illustrating the improved reliability and mutual value creation of such innovation will be presented.

The U.S. Toxic Substances Control Act (TSCA) underwent significant amendments in mid-2016 as the “Frank R. Lautenberg Chemical Safety for the 21st Century Act”, intending to provide the Environmental Protection Agency (EPA) with increased authority to review and regulate new chemicals before allowing them into commerce. Any chemical that is not listed on or exempted from the US TSCA Inventory must undergo a submission to the EPA for review prior to commercial activity. The amendments have impacted the review process for new coatings chemistries significantly, causing delays to market of numerous months and applying restrictions to approximately 85% of new chemicals. This presentation will first discuss the challenges encountered in the TSCA new chemicals review process that impact both new chemical developers as well as product formulators when attempting to bring new coatings technologies to market. Next, we will explore little-known strategies available to avoid the need for a new chemical submission to the EPA, tips for compiling critical information to create the most robust submission when one is required, and how to navigate regulations when they are applied to new chemicals. We will cover how these strategies work best when incorporated during the early R&D stages of product development.

Demand for high performance water-based coatings continues to be the trend throughout many coatings market segments. Significant growth has been seen and is forecasted to continue in the roof coatings market, where demand for long lasting, cost effective barriers can bring significant maintenance cost savings to property owners. Environmental cool roof requirements in major metropolitan cities further require energy efficient coatings that reduce the heat build-up in the region and reduce the energy consumption needed to cool the building’s interior, all by reflecting the energy from the sun’s ultraviolet rays. These demands require roof coating formulators to find cost effective solutions to surpass environmental constraints. Recent research in this area has led to a discovery of a material that provides improved solar reflectivity in addition to anticorrosive properties. These properties have been demonstrated in a white elastomeric roof coating where the primer coat was eliminated and achieved improved adhesion, corrosion resistance, and solar reflective properties versus a traditional primer and topcoat system.

Polysaccharides are important biopolymers with a wide range of industrial and consumer product applications. Historically, structural polysaccharides such as cellulose have been the backbone of early material science for a range of applications also in coatings. A new family of engineered polysaccharides has been developed through the selective polymerization of sucrose to provide materials ranging in molecular weights, solubility, and polymer architecture and particle morphology. The underlying enzymatic polymerization process offers the opportunity to design the polymer structure and the material properties of these new biomaterials. One specific example, the linear alpha-1,3-polyglucose has been assessed for applications in coatings. This material has been tested for its ability to modify the rheological, mechanical and optical properties of interior flat coatings. Our findings suggest that relatively minor concentrations of this engineered polysaccharide has the capacity to function as a substantial rheological modifying (thickening) agent in coatings with attractive sheer-thinning characteristics. The engineered polysaccharide significantly enhances the opacity, whitening, tint-strength and matting characteristics in certain water based coating formulation. With TiO2 costs continuing to increase, the trend remains to identify novel materials that can displace or complement TiO2. A multi-functional material that offers rheology engineering, opacity building, whitening, tint strength, and matting characteristics could be an attractive new additive to the coatings marketspace where several properties can be imparted to a coating formulation with one material.

Distributors are generally known for supplying and maintaining stocks of raw materials to coatings production facilities.  Today’s formulators need the broad industry knowledge, multitude of potential solutions and fast service that only National Chemical Distributor representatives with a broad product mix of resins, additives and pigments can provide.  While individual chemical companies, otherwise known as Principals, will have extensive product knowledge about their specific materials, only distributors can provide a more comprehensive set of solutions and still represent said principal.  They introduce the latest product developments of their principals to the formulator well ahead of national symposiums and publication outlets.  Distributors are often able to provide multiple solutions to the formulators to determine the best possible cost performance option. Distributor representatives are well trained to respond to a formulator’s questions about improving product quality or resolving production or performance issues.  There are few situations which formulators experience which have not been previously addressed in the past.  This paper will expand on the advantages of using the technology, experience and fast response time that only modern Specialty Chemical Distributors can provide.

Formulating waterborne coatings that can retain their viscosity after tinting has always been challenging especially with deep and neutral bases.  Over the years, formulators have developed workarounds to address the issue, but the solutions usually come at the expense of other essential performance characteristics.  For example, the loss of flow and leveling with cellulosic thickeners or the slower filling and inconsistency of bases produced at high viscosity to accommodate the viscosity loss.  Traditionally the poor viscosity retention of association thickeners like HEURs eliminated their viability to address these concerns.  The introduction of the HEAT technology pioneered the use of associative thickeners to help stabilize viscosity loss.   However, there were still some performance benefits with the HEUR technology outside of viscosity retention unmatched until now.  A new twist on urethanes, developed by BYK, combines the unique viscosity retention of the HEAT technology with the added benefits of the HEURs allowing the paint formulator to take the next step toward premium performance.

The ability of coalescents of varying polarity to aid the film formation of model BA/MMA and BA/Styrene latexes was evaluated in the absence and presence of a model hydrophobically-modified, ethoxylated urethane (HEUR) associative thickener. Five coalescing solvents having different polarities were employed. Swelling of the latex particles and HEUR thickening effectiveness were determined using rheology measurements while film formation was evaluated using atomic force microscopy (AFM). The amount of coalescent partitioned into the aqueous phase was quantified using GC/MS. Although similar studies have been reported in the literature for latex/coalescent mixtures, studies in the presence of HEUR have not been reported. HEUR did not show a significant effect on coalescent partitioning; however, the rheology of the system significantly varied with the coalescent. Based on AFM analysis of BA/MMA latexes, HEUR appears to aid film formation. Experiments involving BA/Styrene are underway and the results will be included in the presentation.

An important chemical bond existing in many organic colorants often used for the coloration of polymers is called the “azo” chromophore. Johann Peter Griess discovered the first azo compound in 1858. His discovery subsequently resulted in the multi-billion dollar industry we know today! The first synthetic azo pigments of commercial significance were manufactured over 100 years ago. Since that time, several different classes of azo pigments have been discovered and mass produced for use in the coloration of polymers, paints, inks, textiles and special applications. Even today, work goes on to develop azo pigments representing new unique chemical structures. This paper will discuss the beginnings of azo chemistry. Different classes of azo pigments commonly used by the plastics industry will be reviewed. Starting raw materials, pigment synthesis, processing, and finishing is briefly covered. Examples of how chemical and physical differences of pigments can affect their overall performance properties in paint systems will also be illustrated. Finally, some recent developments in azo pigment chemistry, and the current and future role of azo pigments in paints will be discussed.

Novel waterborne (WB) curing agents based on Cashew NutShell Liquid (CNSL) have been introduced for 2K Epoxy applications. CNSL based waterborne curing agents are very hydrophobic in nature, however a specially designed proprietary technology allows the products to be stable in water without the help of co-solvents. These solvent free WB curing agents have demonstrated very desirable performances including faster cure at low temperature, excellent anti-corrosion performances, outstanding adhesion to various substrates, and good compatibility with both standard bisphenol A/F type resin, solid epoxy dispersions, and various additives. These combined properties provide broad formulation latitude and enable low VOC coatings and adhesives. In this paper Cardolite will present two types of CNSL waterborne curing agents, i.e. solution and dispersion types, and discuss their benefits and properties that meet requirements from different applications, i.e. floor coatings, anticorrosion and container coatings, ACE applications, and tile grouts and adhesives.

Leaching of exterior paints can occur when water condenses on freshly-painted walls, leaving behind shiny, vertical “snail trails” that alter and deteriorate the optical appearance of the surface. This phenomenon happens most often in spring or autumn, when temperatures fall below dew point more frequently. Condensed water is mobilizing water-soluble paint ingredients, which then migrate to the surface. It is still not fully understood which ingredients are extracted, but surfactants are suspected to be a main contributor. They are introduced into the initial paint formulation via binders, pigment paste, as wetting agents and emulsifiers. With this lecture, a test method to investigate surfactant leaching in qualitative and semi-quantitative manner is introduced. The particular cold moisture conditions, under which snail trails form, are mimicked, and the leached paint ingredients can be collected and identified. In theory, chemical bonds to the paint matrix or less soluble, less mobile ingredients should suppress the formation of snail trails on painted surfaces. For this reason, we introduce two innovative paint ingredients. A new reactive emulsifier can minimize surfactant-leaching on the binder level. The emulsifier is bound to the binder particles covalently, thus it cannot leach out when the binder is exposed to cold moisture conditions. In addition, a polymeric dispersant has been developed to improve the complex problem on the pigment paste level. Due to the reduced solubility and kinetic mobility, the dispersing agent stays in proximity of the pigment particles under leaching conditions.

Formulating 50 gm/L VOC architectural semigloss coatings with good early block resistance is particularly difficult in deep and neutral base paints which use high colorant loadings. The surfactants and humectants in the universal colorants can soften the coating and lead to sticking when used on doors and windows. Although some improvement in hardness can be achieved through core shell polymer particle morphology, this is often at the expense of film integrity, giving films with low gloss, poor scrub and poor exterior durability. By using staged phases in the acrylic polymerization process and ambient temperature cure polymer crosslinking, polymers with much better film integrity and hardness are possible. These polymers can give improved early blocking at high colorant loadings, very good scrub resistance and good low temperature film formation in 50 gm/L formulations. A comparison of the performance of low VOC semigloss formulations using these polymers against commercial neutral base semigloss paints will be presented.

There have been a number of claims recently of epoxy materials which are very light in color and which exhibit minimal yellowing. Evaluations were carried out to determine how light-fast these really are. Formulas and test methodologies were developed to better understand how to ultimately reduce long term yellowing. Data will be presented showing how different epoxy formulas yellow and how accelerated yellowing methods correlate with actual exterior exposure.

The top challenges in Direct to Metal (DTM) waterborne industrial coatings remain to be the end performance requirements versus solvent borne systems. However, as the innovation efforts in waterborne industrial coatings continue to advance, the formulators now have better tools to develop latexes with improved adhesion, corrosion and water resistance vs solvent borne formulations. A number of polymer types are used to formulate DTM waterborne industrial coatings and the desire to develop improved and differentiated performance in such formulations calls for a tailored design of the emulsion polymer. Solvay has developed specific functionalities to be built into latex polymers and resins to improve the end performance of these coatings. We will present an overview of these benefits as well as specific examples of improvements in adhesion, corrosion and water resistance for DTM waterborne industrial coatings applications.

In the 1990s, just over one tenth of U.S. natural gas production was produced through unconventional means. By 2007, technological advances in the unconventional extraction of natural gas led to dramatic production cost declines in tight reservoirs, particularly shale rocks. It is expected that approximately 65% of U.S. natural gas production will come from unconventional extraction in 2020. The proliferation in U.S. natural gas supply has driven cost down significantly over the past decade. The price decline has impacted the coatings industry in several key ways. Not only have reduced natural gas prices given coatings producers access to cheaper fuel and power, but they have impacted raw material costs. Ethylene production in particular has benefited from low natural gas prices. U.S. producers of ethylene have shifted to natural gas (ethane) from oil (naptha) for ethylene production and have dramatically reduced costs. Cheap natural gas will give U.S. coatings manufactures secure and cost effective sources of power, energy and raw materials for years to come.

An appropriate, successful product development process is the key to survival and profitable growth for most companies, especially small and medium sized companies. Large companies may continue to grow by expanding markets. Innovative new products fuel the growth engine of successful companies. Being able to move with speed from the idea phase to the implementation phase is imperative. This is especially true within our competitive and quickly moving coatings industry.

There are many ways to manage innovation and new product development (NPD). Large organizations, like Procter & Gamble, have been pursuing their open innovation methodology of “Connect + Develop” for over a decade. Other companies use various versions of stage gate style methods. Selecting and implementing an appropriate process brings control, efficiency and expedition to this vital activity.

Depending on the size of the organization, innovation and NPD may be managed effectively in three to seven phases. It is important to balance needed steps with scale and manageability. For example, a medium sized company may choose a five- phase process of idea generation, screening, concept development, product development and commercialization. While all of the most needed steps are represented, the process is still streamlined and manageable.

Successful companies are disciplined in ongoing strategic portfolio management as well as in prioritizing, resourcing, and if necessary, terminating NPD projects. This paper will elaborate the ways leading organizations manage these critical activities to expedite product development through well-designed product development phases.

A transparent omniphobic NP-GLIDE coating contains in its matrix nanometer-sized pools of a grafted lubricating ingredient for de-wetting enablement. On NP-GLIDE coatings sprayed paint and ink films facilely contract. Further, most test liquids with surface tensions above ~ 22 mN/m have no problem to cleanly glide off. In this talk, I will compare the pros and cons of various ominiphobic coatings including our NP-GLIDE coatings. In our approach, micelles of a graft copolymer are used as the de-wetting enabler. Such graft copolymers consist of a reactive coating precursor bearing low-surface-tension liquid poly(dimethyl siloxane) (PDMS) side chains. The curing of the micelles with other reactive components at a final PDMS content of < 5.0% (m/m) yields the targeted coating. The surface segregation of PDMS in the final stages of coating formation produces a liquid-like PDMS monolayer, which converts a solid coating surface into a liquid-like one and renders the desired liquid-sliding and -contraction abilities. Aside from high repellency for water- and oil-borne contaminants, these coatings due to the insignificant scattering of light by the PDMS nanopools have transmittances higher than 98% in the visible regions of the light spectrum. The binding between a coating and its substrate can be tuned by changing the coating matrix. The coating matrices that we have tested so far include polyurethanes, epoxies, acrylate polymers, engineering plastics, and polymer/inorganic hybrids. The coatings may be cured thermally or photochemically and the formulations may be solvent- or water-based. Additionally, the precursors may be derived from petroleum stocks or renewable resources. While most coatings have a pencil hardness between 2H and 3H, our strongest coating has a hardness higher than 9H, enduring wear by steel wool and being transparent and flexible at the same time. The various formulations should meet the needs for diversified practical applications.

In developing a novel type of polyurethane technology based on polyamide soft segments, we have shown that these materials can be used to make high performance coatings; commercializing dispersions for both metal and wood applications. In this paper, we demonstrate how this novel polyamide-based technology can be used to formulate coatings that provide high quality finishes and conform to specific aesthetic expectations, such as high clarity matte finishes (60° gloss < 10 GU) without added flattening agents or in achieving the gloss and distinctness of image (DOI) like solvent- borne technology but in a water-borne system. Additionally, we have noted that other surface effects can be generated using this technology. Specific properties and the role of the polyamide soft segment in obtaining them will be discussed for wood, metal, and plastic applications.

Choosing a robust polymer system to protect and beautify concrete surfaces is a challenge especially in consideration of modern VOC regulations. Solvent-based solution resin technologies have traditionally provided the favored “wet look” appearance and good penetration while developing strong chemical resistance and film toughness. However, these technologies are formulated only at higher VOC levels. Modern latex emulsions offer capability to formulate at low VOC with serviceable performance for film toughness but often fall short in appearance and water whitening potential of the coating film. Latex emulsions with varying composition attributes are explored for their impact on concrete coating properties such as substrate penetration, water whitening resistance, chemical resistance, and hardness. Variables explored include monomer hydrophobicity and hardness, the presence of internal crosslinking mechanisms, and latex particle size. Novel binders in clear concrete formulations are compared to commercial sealers for overall performance characteristics to demonstrate the potential of modern acrylic latex technologies.

Due to the difference in surface tension between pigments and water, wetting and dispersing additives are being used to obtain good processability for water-borne coatings. Apart from pigment affine groups, these additives exhibit hydrophilic segments to facilitate the system compatibility and provide steric stabilization of pigments. As these components remain in the cured coating, they increase overall hydrophilicity and, thus influence certain coatings characteristics such as water, stain and corrosion resistance negatively. Therefore, wetting & dispersing additives are selected not only by their ability to ensure pigment stabilization, but also by their ability to minimize detrimental effects on water sensitivity. This is especially important for anticorrosive primers, DTM coatings or wood coatings, where stain resistance is required. This presentation presents newly developed dispersing additives based on novel chemical structures, which combine sufficient viscosity reduction and deflocculation of inorganic pigments on one hand as well as least negative influence on water, stain and corrosion resistance on the other hand.

The flexibility of films of asphalt emulsion based sealer with and without the post-addition of fibrillated high-density polyethylene fiber has been investigated. Utilizing five different grades of this synthetic fiber, the nominal diameter of the fiber ranged from 5 to 15 microns, while the nominal length of the fiber varied from 100 to 900 microns. Resulting film flexibility has been shown to increase with increasing synthetic fiber size. Film flexibility also increased uniformly with synthetic fiber application rate, from zero to 2 percent by weight. A link between the reversible elongation of these films, and the ability of the material to continuously fill and seal already cracked pavement has been proposed.

Titanium Dioxide causes up to 45% of the raw material costs in architectural paints and white printing inks and up to 25% in average industrial and decorative coatings. Due to several price increases during the past years the reduction of Titanium Dioxide became one of the main targets for cost savings in paint industry. The use of substitutes or enhancers is only one way – unfortunately often combined with negative influence on the final quality. A much more effective dispersion of the applied Titanium Dioxide is the better way – and guarantees equal or even better product quality. Traditional dissolver discs do not reach a fully colloidal dispersion. A new in line dispersion method creates 1,000 times higher shear rates and 10,000 times higher power density in combination with vacuum expansion of the powder. This way between 2 and 12% Titanium Dioxide are saved. Same hiding power and colour strength are reached with less Titanium Dioxide. The undertone is not influenced since the single particles are not smaller – but colloidal dispersed and better distributed. The surface treatment of the TiO2 particles, which is important for UV stability and weather resistance, is not damaged. Additionally, the new process saves time, energy and space.

New products based on MÜNZING’s organo-modified polysiloxane technology were designed to provide excellent slip and improved scratch resistance in both water and solvent based systems.  Even at low dosages, they demonstrate a strong reduction in the coefficient of friction (COF) compared to similar chemistries used in the industry and were designed to have no foaming tendency or negative impact on the recoatability of the coating.  Additional advantages could also include improved leveling and abrasion resistance. When combined with wax, the two technologies were observed to complement one another resulting in a low COF and highly scratch resistant films. This can add value in many applications, and a case study of improved metal marking resistance using the two technologies complementing each other has been illustrated.

Today most decorative paints are tinted by a combination of specialized colorants. These formulas must provide consistent color development in a variety of paints, remain unchanged during storage, and have minimum impact on film properties. In recent years, low-VOC regulations have driven development of waterborne systems, thereby increasing the difficulty to achieve high quality in a cost-effective manner. The current approach typically requires a combination of polymeric dispersants and auxiliary additives to enable sufficient wetting, separation, and stabilization of the pigments; however issues like foaming, paint incompatibility, and low film quality often arise, which require the use of yet additional ingredients. The result is higher cost and complexity for the paint manufacturer. Stepan has a patented new class of high-performance polymeric dispersants that offers a cost-effective and VOC-free solution to these challenges. In this talk, we will describe our unique approach and share experimental results demonstrating the ability of our technology to deliver high-quality pigmented coatings without the need for other additives. Our focus will be on hard-to-disperse pigments like carbon black and phatlo blue.

Decreasing the VOC emissions of coatings has been a progressive effort for scientists in the industry. Compared to solvent-borne systems, waterborne dispersions generally afford a lower viscosity at equal solids content. Therefore, replacing solvent-borne systems with waterborne dispersions is an effective strategy for reducing VOC emissions. Dispersions, however, often contain processing aids such as initiator fragments and surfactants that can decrease coating performance. The industry has sought to improve the performance of waterborne dispersions, to facilitate the replacement of solvent-borne coating systems. Significant challenges remain, especially in industrial coatings, which demand high performance in corrosion and chemical resistance, UV stability, and gloss retention. Performance in industrial coatings is strongly associated with the presence of a thermoset network formed via a crosslinking mechanism. Reactions with low-activation energy, such as isocyanate-hydroxyl or epoxy-amine, are used to produce thermoset coatings at room temperature and to avoid lengthy and energy-intensive bake schedules. Ambient cure waterborne two-component coatings with poly isocyanates (PIC) provide the opportunity to create high performance thermoset coatings. An appropriate polymer design should enable waterborne technology to achieve comparable performance to that of a solvent-borne system at a lower hydroxyl value and VOC demand. However, formulation with waterborne polyols remains a highly sophisticated task. Introduction of water reducible PICs was the first step toward more robust formulas. An outstanding challenge is the lack of a discernible pot-life marker in waterborne systems. In this presentation, we describe recent BASF efforts to address the shortcomings of waterborne 2 pack urethane coatings. Commercially viable routes were sought to produce dispersions that can provide an end of pot-life indicator in the same manner as their solvent-borne counterparts. A new synthetic platform was used to produce an acrylic polyol dispersion with 70 mg KOH/g hydroxyl value (2.1 wt% OH) and pot-life indication via viscosity increase when formulated with isocyanates. This new resin also allows for low VOC formulations of two-pack topcoats and direct to metal (DTM) coatings which provide superior chemical resistance, good appearance, hardness, humidity, and corrosion resistance. We have also found superior performance in applications on wood and concrete. BASF’s advancement in producing these waterborne resins enables commercial scale synthesis of dispersions with engineered colloidal stability and with a clean water phase (free of salts and surfactants) which is hard to achieve with traditional technologies.

PTFE is a hydrophobic polymer with tremendous chemical resistance due to the strength of the carbon-fluorine bonds.  It is a solid material and exhibits one of the lowest coefficients of friction of any solid polymers.  Due to these properties, PTFE finds use in many applications including non-stick utensils, automotive and medical applications and industrial applications like coatings/inks.  PTFE lubricates the coating or ink surface preventing damage during fabrication, transportation and eventual product use.  This presentation will review the pending update to Annex XVII of the REACH Regulation citing Perfluorooctanoic acid (PFOA) and potential impact on PTFE materials. We will discuss the challenges our industry faces to find suitable alternative raw materials providing equivalent lubrication properties. Finally, we will review alternative PTFE technologies and how Lubrizol is exploring them to protect cured coatings and inks from abrasive forces.

The choice of a thickener system plays a critical role in setting the rheological profile of a coating. Cellulose based rheology modifiers have been used to thicken waterbased paints and coatings for well over five decades. For a variety of reasons, including application performance, cost, and susceptibility to microbial attack, there has been a general market movement away from cellulosic thickeners to associative thickeners. HASE associative thickeners are based on hydrophobically modified alkali swellable acrylic polymers, and although they offer a variety of performance benefits, they traditionally have not offered the in-can feel, dilutability and storage stability of cellulosics. Recent advances in HASE chemistry have enabled significant improvements in these performance properties. New products based on these technologies provide better options for replacing cellulose thickeners in high PVC, low volume solids coatings target to the contractor applied architectural market. This presentation will show how recent advances in HASE thickener technology can replace cellulosics and hydrophobically modified cellulosic thickeners in high PVC formulations, resulting in reduced cost, increased thickening efficiency, improved application performance and better microbial resistance, while maintaining the in the can feel and dilutability of coatings formulated with cellulosic thickeners.

The coil coatings market has experienced steady growth in recent years as it provides an efficient, cost- effective, and environmentally conscious method to coat metal on a large scale. Persistent challenges for coil coatings manufacturers include lowering cure temperatures, improving resistance properties and increasing overall efficiency while maintaining appearance. Variations of aluminum and galvanized steel substrates are typically used for coil applications. Each of these substrates are available with multiple surface pretreatment options. Although each substrate and pretreatment provide unique benefits, variability in substrate and/or substrate pretreatment can present challenges when attempting to meet specific film performance requirements. Optimization of catalyzed melamine crosslinked coil coatings is a complex process, particularly when selecting a catalyst. This presentation is a review of studies demonstrating catalyst activity dependency on substrate and substrate treatments. It also introduces new versatile catalysts that can yield desired properties of films cured at low temperatures regardless of the substrate.

In today’s business environment, there are some major challenges for coating formulators: cost pressure, compliance with government legislation, including VOC and product safety (toxicology), and worldwide registration of key raw materials in today’s global environment. The main work of interest for the R&D community is improving performance with innovative products. However, this is only relevant when it can contribute to these major challenges. Improving performance and introducing innovation just for the sake of the art is no longer of interest in most market segments and is restricted only to niche applications. There are many ways to improve the economics of installations other than negotiating a lower per pound price. This presentation will present the benefits of improved performance of epoxy coating systems for better cost efficiency and simplicity. The strengths and weaknesses of various epoxy curatives used in the current coatings market for low temperature curing, two-component epoxy binders are summarized. These are then compared to two new types of Mannich base hardeners developed by Huntsman Advanced Materials to facilitate development of high-solids formulations with fast low temperature cure and long pot life.

Due to the lamellar nature and the aspect ratio of metal effect pigments, it is very important that the dispersion of metal effect pigments be optimized in a coating formulation to insure a smooth, bright appearance free of defects. Typically, metal pigments are pre-dispersed prior to addition to the coating by mixing the pigment with carrier (solvent or water, depending on if the coating is solventborne or waterborne) and optionally a dispersing aid. This study investigates the effect of dispersant technology on the dispersion performance of an aluminum pigment in three resin systems: acrylic urethane, epoxy, and polyester melamine. Dispersant performance will be reported as response to measurement of application properties, brightness, film smoothness , and dispersion viscosity. Recommendations for best practices of formulating and dispersing will also be made to optimize dispersion of metal flake pigments.

Most water based architectural stainblocking primers typically have only moderate stainblocking performance and they are designed to lock stains in the primer coat rather than block stains. This leads to a major performance difference compared to solvent based primers – since the stain is visible in the dry film when a bleeding substrate is coated with waterbased primer, the painter can not tell with any degree of certainty if the stain will bleed into the topcoat. Novel cationic waterbased primers offer far superior stainblocking and are similar to solvent based primers because stains are blocked by the primer coat rather than locked into the primer coat. For these cationic primers, however, manufacturing procedures and raw materials are different from those typically used in the anionic architectural coatings. Formulation and performance of these new generation cationic stainblocking primers will be discussed.

Waterbased acrylic elastomeric roof coatings have become a hot topic lately. One of the reasons is that they reduce the heat absorption of the buildings when compared to the traditional asphalt roofs. In addition of heat prevention and energy savings, acrylic roof coating protects the underlying material from water, UV radiation, chemicals and wear. Waterbased acrylic roof coatings are typically thickened with cellulosics (HEC) and associative thickeners (HEUR, HASE). Their use can often lead to challenges in both water resistance and absorption of the coating. In addition, the control of syneresis and sagging is often a challenge. Microfibrillated cellulose (MFC), a bio based and multifunctional product made of cellulose, consisting of fibrils with lateral dimensions in the nanoscale and lengths up to micron scale. The fibrils have the ability to form stable three-dimensional networks in coatings, leading to excellent stability and flow as well as anti-sag properties. We will demonstrate how MFC improves the key properties of acrylic elastomeric roof coatings, such as tensile strength, water resistance and adhesion to metal and concrete surfaces, compared to commonly used thickeners. The effect of the fibrillation degree on the mechanical properties of the coating will also be discussed.

There have been significant changes in the regulations governing the use of volatile organic compounds (VOCs) in coatings. Wet edge and open time are often compromised when humectants like ethylene glycol and propylene glycol are eliminated, and coalescing agents reduced in the coating formulation. This makes the formulation of waterborne coatings more challenging to get an acceptable balance of properties both during application and drying process of the final film. Materials that slow down the evaporation rate of water help to improve the workability in paints. Munzing has developed several open time additives (OTA) focusing on improving the workability of low VOC coatings. These open time additives (OTA) improve the open time/wet edge time and maintain recoatability window without negatively impacting the desired film properties. Effective pigment orientation in waterborne coatings was always a challenge.  Munzing has developed a unique technology for improving pigment orientation in waterborne coatings. The presentation will focus on new Munzing technology on OTAs, pigment orientation additives and new aqueous emulsions for improved scratch and abrasion resistance.

As a part of the metal plating process – whether steel (galvanized, cold-rolled, etc) or aluminum – a clear coating is applied following the conversion and passivation processes in order to further protect the surface.  In addition to the protective functionality, it is critical that the sealer have sufficient clarity so as not to impart any noticeable haze to the substrate.  Further, for specialty applications such as fasteners, this coating cannot significantly impact coefficient of friction which would, in turn, affect the torque (per ASTM methods) which would be required in use.  To meet these performance challenges, we have develop waterborne coatings based on copolymer dispersions which have been shown to meet or exceed the performance of existing commercial products – on both panels (aluminum and EZG steel) and actual fasteners.  When used in conjunction with Zn-Ni and trivalent chromate treatments on steel panels, these coatings provided >2000 hours of salt spray resistance (ASTM B117).  Similar results were seen for coated M10X90 6921-8.8 HFB steel fasteners.

Thickeners are included in coating formulations to give specific rheological properties. A coating’s rheology influences its properties during manufacture, storage, application and can influence dried film performance. Two types of thickeners are available to waterborne coatings: Non Associative and Associative. Both class of thickeners aid coating’s manufacturing and storage properties. However, they differ in application and in the final dried film properties. Non associative thickeners are Cellulosic and Acrylic based. These coatings have poor application properties. Associative thickeners are available in three categories to waterborne coatings –Hydrophobically Modified – Cellulosic (HMHEC), Acrylic (HASE) and Urethane (NiSAT) thickeners. Urethane thickeners offer waterborne coatings excellent application and overall dried film performance property outperforming both HMHEC and HASE thickeners. Performance of Urethane associative thickeners has usually been a compromise of positive and negative features. They associate effectively with hydrophobic binders, but face challenges when used with hydrophilic binders. Our recent advances in Urethane thickener technology have allowed for a significant step forward in performance of waterborne coatings based on hydrophilic binders. This presentation will show how advances in Urethane thickener technology are now providing architectural waterborne coatings based on hydrophilic binders with optimal thickening efficiency and superior application with improved dried film performance properties.

Today’s paint and coating formulations are constantly striving to be environmentally friendly. Now, “being green” can be transformed onto the factory floor. Operations managers are under constant pressure to meet deadlines while continuing to find ways to lower overall production costs. These issues can be overcome by using improved pump technologies while significantly lowering energy and maintenance costs. Using electric VFD controlled peristaltic and diaphragm pumps for specific raw material transfer, process transfer, and filling applications provide unique opportunities for improvement. Understanding how your local Utility Company can assist with the initial purchase combined with reduced daily energy consumption is critical to lowering costs. By employing specific pumping technologies in key applications, KWh consumption can be reduced by factor of 5x or more. An understanding of these technologies allows for continued process improvements while lowering total overall operating costs.

AAA study finds that cloudy headlights pose huge safety risk (11 December 2018). Degraded car headlights can greatly reduce the amount of light projected at night. AAA also finds that the average 11-year-old vehicle’s headlights generate 20 percent of illumination as new headlights. Polycarbonate (PC) is attractive as an important transparent material due to its high impact resistance, low density, high thermal stability, excellent optical properties, and so on. However, PC exhibits low hardness, poor abrasion resistance, and poor UV and solvent resistance, which limits its applications greatly. Low MFFT, self-crosslinking aliphatic polyurethane dispersions (PUD) were evaluated due to its excellent adhesion on PC, and exhibited toughness, abrasion resistance, flexibility and chemical resistance. In this study, we are testing these water-based, non-flammable polyurethane formulations on SABIC LEXAN sheet (interlocking polycarbonate wall #3440). Performance and product stability are the two big issues when developing the formulations. The results of compatibility testing (performed by SABIC) and Florida outdoor exposure testing (ASTM G7) will be discussed. Overcome the product pH drop during long-term stability is a challenge. The use of waterborne UV stabilizers, surfactants, neutralizing additives, and ultrafine TiO2 particles to prevent the change of pH will be discussed. Further work has explored the application of these formulations in market areas such as automotive headlight protection and restoration. The use of bag-on-valve (BOV) technology as the product carrier is also presented.

A new coalescent platform has been discovered which yields improved hardness, block resistance, scrub resistance, and dirt pickup resistance versus the traditional high VOC coalescent 2,2,4-trimethyl-1,3-pentanediol monoisobutyrate, with even more dramatic improvements over the commonly used low VOC coalescent, triethylene glycol di-2-ethylhexanoate. This new platform, which can be formulated to achieve <10 g/L VOC, has been found to have multifunctional properties in that it functions both as a coalescent and as an additive which greatly enhances in-can preservation against common problematic microbes, reducing traditional isothiazolinone or other biocides.

Terms such as anti-dirt, anti-stain, anti-soil, anti-graffiti, easy-care, and easy-to-clean are used almost interchangeably for essentially the same phenomenon: surface repellency of particles and liquids. Among approaches to these types of surfaces, coatings modified with additives to provide highly hydrophobic or highly hydrophilic surfaces represent attractive options. This paper will discuss how manipulation of additive polymer architecture and functionality can influence the energetics of a coating surface, and how these properties can in turn impact the ability of a coating to resist adsorption or facilitate the removal of soils. The challenges associated with development of additives to provide these effects for a variety of coating systems will also be discussed.

Vinyl acetate-ethylene (VAE) copolymer emulsions are renowned for their ability to be formulated in environmentally friendly coatings with minimal use of coalescents or additional solvents to produce low VOC, low odor interior architectural paints. Paints formulated using VAE copolymers, in addition to being VOC-complaint, display excellent scrub resistance and touch-up properties compared to conventional pure acrylic- or vinyl acrylic-based systems. However, in non-flat formulations, VAE-based paints show poor block and dirt pick-up resistance. Paint formulators have frequently blended VAE emulsions with pure acrylics to overcome these limitations, often at higher overall formulation cost. We have used novel techniques to modify the chemistry and morphology of conventional VAE copolymers. These modifications allow paint formulators to improve VAEs’ performance capabilities, such as block resistance, and extend their use to non-flat formulations. By incorporating these changes into the polymer, the need for blending VAEs with pure acrylic binders is eliminated. In this presentation, we show formulation and testing results on VAE-based semi-gloss paints with higher block resistance.

There is a primary market need to design resins and coating formulations that adhere to the many surfaces that an end user may coat while maintaining other performance properties. As the coatings industry converts more to waterborne technologies, strategies once used to improve adhesion are no longer an option. This talk will present an overview of common substrates, legacy strategies that have been employed to adhere to them, and new waterborne polymer and formulation strategies allowing conversions away from solvent. For example, low surface energy substrates such as thermoplastic olefin (TPO), in particular new TPO, is notoriously difficult to adhere to due to the lack of chemical functionality to improve adhesion. Data will be presented demonstrating how newly developed waterborne acrylic resins and their coatings formulation can impact, and in the case of resin choice, dramatically improve adhesion, especially to metal, concrete, TPO, and other hard-to-stick-to surfaces.

Epoxy coatings are ideally suited for industrial and protective applications due to the polymer’s resistance to chemical and mechanical damage. Coatings based on waterborne epoxies, including epoxy emulsions, offer a safer and more sustainable means of achieving long service lifetimes in asset-protecting coatings. A novel polymeric emulsifier has been developed which not only offers compatibility with a broad range of liquid and solid epoxy resins for efficient preparation of stable emulsions, but also maintains barrier properties of the binder and coating. Corrosion and chemical resistance as well as adhesion data will be shown comparable to coatings based on solvent-borne epoxy resins, and superior to those based on water-reducible or presently available epoxy emulsions. Waterborne acrylic dispersions are less commonly employed in DTM applications, but offer advantages in ease of application as a 1K system. New data shows that use of novel reactive surfactants in their synthesis can increase barrier properties and corrosion resistance to suitable levels for these demanding applications. Emulsifier developments and the performance of representative formulations for both resin systems will be discussed in detail.

Waterborne coatings are becoming increasingly popular because they offer several environmental benefits such as providing a solution to the increasing VOC stringent regulatory requirements. However, many of the major short  falls of water-based coatings  compared to solvent-based are outdoor weathering and surface effect properties such as scratch resistance, water repellency and surface feel. In case of poor weathering, water-based coatings without proper light stabilization will undergo  rapid color fading,  subsequent to cracking and blistering. Hence, in the intended presentation, we will share some key performances of novel additives developed to further improve the overall performance of water-based coatings. Such unique Clariant additives enable coating formulators to offer state-of-the- art weathering durability as well as providing smooth surfaces with the pleasant feel of texture or silky surface.  These additives also offer outstanding scratch resistance and high matting efficiency when necessary.

Additives are components of a formulation that are added in small quantities to provide special properties to the wet paint as well as the dry film. Surfactants, in particular, affect the behavior of paint not only during the lifetime of the formed coating, but also initial aggregation and film formation of the paint. Surfactants not only allow the paint to coat a surface more easily due to increased wetting ability of the coating, but are also very critical in providing good color acceptance, stability, and overall performance requirements. However, over the last decade, APE-containing (Alkyphenol Ethoxlate) surfactants are being replaced by APE-free surfactants due to biodegradability, toxicity of degradation products, bioaccumulation, and possible endocrine disruptor. As such, APE-free surfactants are needed that will not only address the environmental and health concerns, but also perform similar to APE-containing materials. This talk will highlight a new APEO-free surfactant that can easily replace APE-containing surfactants in the formulation and provide equal or improved performance across a variety of binder chemistries and formulation spaces.

Polyester films have a broad range of commercial applications and are widely used in the flexible packaging industry, in which a heat sealable layer is often needed to bond to other packaging substrates. Due to the poor adhesion to polyester films, certain common heat sealable coatings are unable to be directly coated on polyester base films. Thus a primer layer is required under such circumstances. There have been very few polyester film primer coatings developed in commercial process. We report here a novel primer coating involving cross-linkable EVA (ethylene-vinyl acetate) for heat sealable polyester films. The readily available coating raw materials and the ease of cross-linking reaction under mild conditions make this coating more attractive and competitive compared to existing primer coatings for polyester films. Moreover, the novelty of cross-linkable EVA resins in primer coating make it possible to introduce new heat sealable coating chemistries to current polyester packaging film industry.

Previously we demonstrated that polyamide soft segments can be used in urethanes to make materials for high performance coatings, and we have commercialized several products for both metal and wood applications. The highest attainable solid content for waterborne polyurethane dispersions is lower than what can be achieved by acrylic emulsion. In this paper, we demonstrate how this novel polyamide-based technology can be used to make high solids waterborne dispersions with over 50% solid content, approaching the limits of acrylic emulsions while maintaining a high Tg polyurethane. The increased solids content has several benefits for coatings applications. Including the elimination of a coating step, thicker coatings, reduction of dry time and lowered coalescing solvent need. The combination of these advantages and the well-known high performance of the polyamide urethanes is expected to be a valuable benefit to a large variety of coating applications.

Over the past few decades much emphasis has been placed on the importance of surface preparation impact on anti-corrosive protective coating performance, particularly for maintenance applications where the barrier coating has been compromised and resulting corrosion is present. Typical blast cleaning will remove the aged coating and rust corrosion products, but the invisible issue remains in soluble salts. There are various ways to extract and test for the surface salts, but the most efficient and accurate is with a slightly acidic solution that is then titrated for ion specific (chloride, sulfate, and nitrate) levels. Using a slightly acidic complexing surface wash will then remove the soluble salts down to undetectable levels providing for an uncontaminated surface for application of the protective coating. The following presentation will review new corrosion rate data for the different salt chemistries at different temperatures with different dissolved oxygen concentrations. Also discussed, is the impact of the surface salts on a rusted steel substrate’s impact on epoxy barrier coating performance versus a new panel performance. And lastly, review of a soluble salt removal solution application to remove salts but not rust and the resulting coating performance.

The coatings world has become very familiar with a variety of biorenewable feedstocks to hybridize film properties and performance, replacing petroleum-derived feedstocks.  Continued reliance on the petroleum basis for coatings ingredients has been identified as non-sustainable.  This, much like the continued reduction in solvent usage and the identification of hazards associated with many metal-based catalysts and corrosion additives, will drive the efforts to find alternatives in resin and coating technology for the benefit of future generations.  These trends and drivers coupled with an ever-shrinking capacity for waste disposal and its associated environmental impact has created an epic crisis and opportunity.  The coatings space has embraced this, and validation of recycled material utility has begun.  We will describe how varying levels of recycled poly(ethylene terephthalate), rPET, can not only replace significant amounts of petroleum-based intermediates, but can improve properties of coatings for many industrial applications.  Combining rPET with various biorenewable ingredients in the right proportions can help us protect metal substrates and reduce heavy metal additives, while navigating this crisis and opportunity.

Siloxane-based additives are critical tools in coating applications because their structures can be varied in order to provide a broad range of performance benefits in many types of formulations and chemistries. Surfactants and defoamers are some of the more commonly recognized additive classes, but many other functionalities can be derived from siloxane chemistries, particularly attributes related to surface control such as flow and leveling, slip, scratch resistance, and haptic properties. This extensive range of performance is achievable due to the broad flexibility inherent in siloxane chemistry, allowing a fine-tuned balance of compatibility, incompatibility, and surface activity. As with many additive types, a broad range of functionalities creates many options for improvement and innovation but also presents challenges in finding the right additive and optimizing to achieve the desired performance. This presentation will attempt to clarify the general structure-property relationships that drive the performance attributes of siloxane additives and detail the continuum that exists between wetting, leveling, defoaming and slip within this chemistry class. Surface control properties and testing will be reviewed and related to recent evaluation work conducted in developing novel siloxane surface control additives.

Improved applied hide is a continuous need from both the professional and do-it-yourself (DIY) architectural coatings market. Increased solids and titanium dioxide loading are two ways formulators have attempted to meet this need. However, there is only so much hiding improvement to be gained before reaching a point of diminishing returns. This challenges formulators to explore alternative methods to improve applied hide. These can include anything from changing dispersant and surfactant packages to new rheology modifiers. This presentation will examine two different rheology modifiers: traditional, linear hydrophobe rheology modifiers and novel, complex hydrophobe rheology modifiers. It will utilize innovative techniques to quantify and discern how differences in rheology modifiers can affect applied hide as viewed by the consumer. Understanding how rheology modifiers affect applied hide will enable formulators to design architectural coatings with improved applied hide as well as offer a potential for cost-savings through optimization of titanium dioxide loading.

Corrosion prevention is a key requirement for the Protective Coating market. The traditional tools (anti-corrosive pigments) have come and continue to come under environmental pressure. The challenge is to develop novel anti-corrosive systems with performance equal to that of current anti-corrosive pigments which extend performance life. Prior work by Applied Graphene Materials has demonstrated that very small additions of Graphene Nano-Platelets (GNPs) decrease water vapour transmission rates and extend time to initial onset of corrosion when compared to existing zinc phosphate based systems. The mechanism of Graphene’s action has however been controversial and several mechanisms proposed in literature. This work benchmarks GNPs against and in combination with commercially available anti-corrosive pigments via electrochemical, accelerated corrosion, and mechanical testing. We seek to characterise the mechanisms by which GNPs work as anti-corrosive pigments and investigate synergistic effects which will allow improvements in coatings anti-corrosive performance.

Two of the major “big box” stores each have a wide range of quality paints supplied in a variety of colors and sheens. The leading brands for each of them are two of the largest paint suppliers in North America. These paint companies each have their own strategy for meeting customer needs through their paint application performance and durability. This presentation will examine similarly priced and marketed paints from both paint suppliers in their respective big box stores. During this talk we will compare and contrast a variety of their paint attributes, ranging from “in can” properties including stability and odor; application attributes such as rheology, wet hide, and dry time; and dry paint properties demonstrated by dry hide, sheen, scrub, washability, adhesion, and surfactant leaching. Additionally, by utilizing the appropriate analytical tools, the underlying chemistry that imparts these properties were investigated and will be reported. Results include pigment volume concentrations, latex types, and VOC content, all of which are standard tests in the industry. More sophisticated tools such as GC/MS, GPC, HPLC/DAD, SEM/EDX, and TEM were employed to elucidate the chemical makeup and morphology of these premium paints, and thus provide insights into the making of a quality product.

Performance expectations of high chromatic colorants, especially organic reds have increased over the years along with the popularity of bright outdoor colors. Pigment yellows including 3, 65, 74, 97, 110, 138, 155, 184 and 184/74 blend will be compared via Xenon arc accelerated weathering as colorants in commercial exterior bases with different levels of titanium dioxide (ultra-deep base and medium tint base). Measurements discussed compare CieLAB, Delta E, and strength at 500, 1000, 1500, and 2000 hours in a Q-Sun Xe 3HS weathering incorporating ASTM G-155 Cycle 3; Standard Practice for Operating Xenon Arc Light Apparatus for Exposure of Non-Metallic Materials. It is worth noting that each of these pigments possesses a firm place in industry because they satisfy some need which exists in the market. The importance of this comparison is to assist the user in determining the proper yellow pigment for their application. The value of these pigments will also be compared with respect to relative cost and weathering performance.

Waterborne acrylic emulsions have long served as resins for general industrial applications. However, recently they havat low VOC, emulsion polymers often lack the capability of balancing hardness, adhesion, and anti-corrosive performancecoatings, limiting use in direct-to-metal (DTM) applications. For optimal performance in these demanding applications, it is critical to understand relationships between the resin composition and the coating formulation. In order to adhere to the strict performance specifications of a diverse landscape of end users, coatings manufacturers will typically implement a multicoat primer/topcoat system. These systems then require separate applications and thus increase the return to service time. Factors that influence successful DTM formulations will be discussedthe properties of such systems are elucidated here, including pigment volume concentration, extender chemistry, extender particle size, and polymer compositional variables. How these factors affect water uptake, film hardness, adhesion, and salt fog resistance will be examined. From this study, a one-coat <50g/L VOC coatings system that provides comparable performance to a two-coat primer and topcoat system will be highlighted.

Companies are often forced to internally debate whether to apply for a patent or keep the invention “secret.” This question is particularly ripe in the field of coatings, where the formulations are cumbersome, if not impossible, to reverse engineer. Thus, the consequences of the public disclosure mandated during the patenting process can be especially harsh if an attempt to obtain a patent is ultimately unsuccessful. This presentation will explore the essential factors that should be balanced when debating whether to apply for a patent or maintain a trade secret. This presentation will also discuss relatively new procedures at the United States Patent and Trademark Office that, if leveraged correctly, will allow an Applicant to gather critical information and make an informed decision.

The usage of near zero VOC architectural bases and low VOC colorants is increasing in North America. Both paint companies and colorant suppliers have advanced their knowledge and tools for successful low VOC formulation of their products. Additive companies have now joined in and the tool box is larger with the advancements in surfactant and dispersant technology for low VOC applications. What is the definition of a “universal” additive? What is the definition of a “water only” additive? Within this study are a series of tests comparing colorants made for universal architectural application and water only application. Several different types of architectural bases were used to compare five complete colorant lines. Tests performed include viscosity drop, blocking resistance, surfactant leaching, scrub resistance, open time, and base compatibility. What are the benefits and disadvantages of each colorant line. What problems remain in the market? What is next in the line for technology of architectural Low VOC resin free colorants.

Dry film biocides are used in exterior coatings to maintain coating quality and appearance by reducing the risk of degradation of the coating from microbiological sources such as fungi and algae. The long term performance of these additives is a function of both their intrinsic efficacy as well as maintaining a sufficient concentration within the coating for a desired lifetime of the coating. This performance can often be limited by both environmental factors such as rain or sunlight, resulting in leaching or decomposition of the biocide, but also by increasing regulatory concerns with respect to environmental exposure to the actives. In this regard, we report the development of a high performance encapsulation technology and key considerations for the development and use of encapsulated technologies in exterior coatings.

Alkanolamines, such as 2-amino-2-methyl-1-propanol (AMP) and 2-amino-2-ethyl-1,3-propanediol (AEPD), are commonly used as key stabilizing agents in a wide range of waterborne paint formulations. The versatile performance of these Alkanolamines, and their synergistic effect with a wide range of commercial dispersing agents, can help formulators achieve optimum particle size distribution of titanium dioxide, which leads to ideal light scattering that drives dry film opacity. This research evaluates different blends of dispersing agents and alkanolamines to explore the evolution of particle size during the dispersion, as well as analyze the isoelectric point as a function of the pH, adsorption of alkanolamines at pigment surface, and the evolution of slurry rheology to highlight optimum combinations of chemistries. This comprehensive work should help formulators to improve final dry film performances.

Development of durable exterior products is limited due to the need for years of real world exposure. To shorten development time, the coatings industry relies on correlating exterior data to accelerated weathering, most typically in the form of cyclic UV/condensation tests. These tests still take months to complete and lead to extensive development times. A method utilizing ATR-FTIR has been developed that monitors degradation of coatings from UV light on a molecular level. This approach detects changes in oxidation at the surface of a film well before an impact to gloss is observable and allows sample differentiation in weeks rather than months. Combining this mechanistic approach with traditional accelerated weathering and exterior exposure methods, establishes an exposure program that guides the development of coatings with leading dirt pickup resistance and gloss retention performance.

Pigments are chemicals that absorb and scatter visible radiations, and are generally dispersed in a medium to create an appearance, known as color. There are hundreds of commercially available pigments, which offer a number of choices in shades, physical properties and cost of use. A formulators’ common dilemma is know which pigments they should use for their particular application. A good understanding of a pigment’s capabilities and limitations (heat stability, durability, hiding, and cost) and performance differences are necessary for customer satisfaction.

In this presentation, our discussion will focus on basic chemistry, the physical and the chemical properties of pigments which can be used as a guide for selection to arrive at the optimum formulation for your application. We will explore pigment limitations, such as heat stability, solvent resistance, weather fastness, and opacity.

Metallic copper’s antimicrobial properties are well known. Copper kills microbes via multiple mechanisms that render it highly potent against human pathogens, including antibiotic-resistant “superbugs”. In 2008, the US EPA introduced a new test protocol for the registration of copper metal and copper-alloy surfaces with claims of bactericidal efficacy against human pathogens. However, utilizing metallic copper surfaces for infection control comes with drawbacks of cost and appearance. Our innovation – copper-containing glass powder, harnesses the antimicrobial properties of copper by stabilizing bioactive Cu(I) ions and making them available by a slow-release mechanism. The glass powder readily disperses in water, has broad-spectrum efficacy and a favorable toxicological profile. Latex paints containing copper-glass powder exhibit ≥99.9% reduction in bacterial colony counts when evaluated by the US EPA “test method for efficacy of copper-alloy surfaces as sanitizer”. Incorporated at low concentrations, copper-containing glass powder is an effective “in-can” preservative, preventing bacterial contamination by Pseudomonas aeruginosa and Enterobacter aerogenes when tested by ASTM D2574. Given the challenges of infectious disease control and concerns with toxic biocides, the copper-containing glass powder offers a pragmatic and broadly deployable solution for antimicrobial coatings.

This paper will discuss hyperbranched polyester polyol technology for improved 2K polyurethane coatings. Hyperbranched aliphatic polyesters can have hydroxyl and acid functionality and a high end-group density. Since they are more spherical in shape than linear, there is less polymer chain entanglement and a lower viscosity than seen with linear polyester polyols with similar functionality. Studies show that hyperbranched polyols can be used as a co-binder with a high-solids acrylate to improve curing and applications properties at low VOC. Other advantages include improved hardness and chemical resistance. The data show that incorporation of hyperbranched polyester polyols not only improve film properties but allow a longer pot life and curing at decreased temperatures. Applications of this technology include, but are not limited to, automotive and industrial coatings.

In the transition from solvent borne technology to waterborne technologies, the customer of the coatings industry has the same performance requirements without change. The primary purposes of a coating are to improve the appearance and protect the substrate.  Those two reasons are what the customer expects. To that end, the formulator seeks to develop the most cost effective coating that meets those primary requirements. A defect free coating gives the best appearance and helps to maintain the integrity of the substrate. This talk will discuss the differences between formulating for solvent and waterborne coatings.  Starting with the difference types of pigment stabilization and what the stabilization mechanism brings to the coating formulation. Moving onto the prevention of defects in the applied film, and the control of the surface tension variations that cause undesirable material movement. The film formation differences between solventborne and waterborne technologies will be discussed and how the formulator addresses these differences.
