Using Artificial Intelligence for Trend Forward Formulating
How can a formulator use trend predictions to accomplish their projects? Where can you find the information needed to foresee important trends? What new regulations will be implemented around sustainability issues such as environmental effects, biobased materials, worker and consumer safety, and chemical exposure? Try giving Artificial Intelligence (AI) a try. No one can predict what the future holds for the coatings industry, but just like a hedge fund manager, we can make some of those âforward looking statementsâ cautioned about in every prospectus. There are a lot of hopes and fears connected with the use of AI. These range from enabling a more peaceful, bountiful society to the world envisioned in the Terminator franchise. One hopes that reality is somewhere in between those extremes. This presentation will explore how AI can be used by the coatings formulator to help clarify trends such as sustainability, smart coatings, digitalization, customization, advanced formulations, health and safety, and biobased materials. AI gives the formulator powerful tools to improve their coatings in many ways.

Bio-based High Solids Polyamide Polyols for Protective Coatings
Milena Garay-Tovar, Gabor Erdodi, Samantha Detgen, Chandra Pandey
Polyurethanes are one of the most versatile materials for solvent borne protective and industrial coating applications, with innovation increasingly focusing on sustainability and emission reductions. Lubrizol has developed a novel soft segment chemistry for polyurethanes using polyamides, which in the past few years has been successfully incorporated into high performance waterborne coating products. We now introduce polyamide polyols for solvent borne polyurethane topcoat applications targeting protective and industrial markets. Coatings made from these novel polyols provide excellent solutions for applications where weatherability, color stability, and gloss retention with good adhesion to primer and metal surfaces are critical. They can be formulated into high solid, low volatile organic content (VOC) paints (<250g/L) contributing 70% bio-content to the coating system that can be fully cured with reduced levels of catalysts or tin-free versions, enabling sustainable solutions. We found that the use of polyamide chemistry imparts enhanced mechanical and barrier properties to the polyurethane, providing high solvent resistance and a tough film with a combination of hardness and flexibility. Formulated paints have high performance with all relevant aliphatic isocyanates without the need to combine different polyols, although the new binders do show good compatibility with acrylic and polyester resins. In this talk, we will present a solution to the most challenging environmental issues of the solvent borne industry by leveraging high solid bio-based polyamide polyols integrated into a coating system with high performance and sustainability.

An extensive background with all rheology modifier technologies  and other coating ingredients used in paints .
The use of rheology modifiers beginning over 40 years ago- initially solvent based lacquer and alkyds, thru technology developments of todays latex systems, and concurrent coating coloring systems.
Understanding the development and importance of wetting/dispersant/surfactant interactions, Â leading to many of todays advanced rheology modifiers. The interfacial relationship between latex-pigment-filler- wetting/dispersing agents and rheology performance make todays formulator more dependent and knowledgeable of total system performance . Patchamâs expertise resides in managing the interfacial relationships brought by all the many paint ingredients.
What does Sustainability mean to you?
Sustainability in our industry means more than the replacement of fossil fuel based raw materials with a more environmentally friendly version that might have less detrimental impact on our planet. There is much more to sustainability than just the ingredients we use to make and formulate organic coatings. Amongst the many factors are energy usage, waste disposal, coating service life, fossil fuel usage efficiency to produce the EF alternatives, market acceptance of the new formulation, and the marketing benefits of claiming to be sustainability.
What does this all mean? The claim of sustainability is very vague depending on the view of justification of the claimant.
Is biobased, non-fossil, renewable raw material sufficient to claim sustainability?
What about service life, and cost of product application in cases of labor intensive maintenance service schedules?
This presentation aims to discuss a more total approach to sustainability in terms of upstream as well as downstream impact, power consumption, and service life and their overall impact on sustainability.

High Solids TEA-free Waterborne Polyurethane Dispersions
High solid content polyurethane dispersions (PUDs) can help deliver both sustainability and performance features in waterborne polyurethane coatings. The highest attainable solid content for waterborne polyurethane dispersions is lower than what can be achieved in acrylic emulsions. In this presentation, we show our journey using novel technology to guide the development of several high solids waterborne dispersions with over 50% solid content, approaching the limits of acrylic emulsions while maintaining a high performance 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. These products were also designed with regulatory needs in mind and have been developed without the use of TEA or NMP. The combination of these advantages and the well-known high performance of the polyurethanes is expected to be a valuable benefit to a large variety of coating applications.Â

Advances in 1K PVDF/Acrylic Hybrid Dispersion and their Applications
Waterborne coatings formulated utilizing aqueous hybrid dispersions of polyvinylidene fluoride (PVDF) and acrylic resins have a long history in the architectural market space. They exhibit exceptional weatherability and can meet stringent VOC requirements and sustainability targets. For applications requiring strong chemical resistance, hydroxy-functional PVDF-Acrylic dispersions are available, which allow formulators to build resistance properties with isocyanate crosslinking (2K). However, coating formulations containing isocyanate have several drawbacks that can limit their widespread usage. These concerns include respiratory hazards to paint applicators and their environmental impact when applied in field applications. A concern for the coatingâs formulator, is micro-foaming in the resultant films due to CO2 generation during the reaction of isocyanate with water. Recently, new self-cross linkable (1K) PVDF/acrylic hybrid latexes were successfully developed, which give comparable performance to 2K isocyanate-based systems. In addition, they can be formulated at <100 g/L VOC.  These advances widen the end-use applications in the current market space and expand their usage into other market spaces. The detailed properties, such as detergent resistance, chemical resistance, dirt pick-up resistance, and target applications as architectural facade coatings and protective coatings will be presented.

Sustainable technology enhances the future of colorant tinting systems
Sustainability is becoming increasingly important in the architectural waterborne coatings industry, whether to meet regulatory requirements or growing customer and consumer demands. One of the primary issues facing traditional colorants is the everincreasing pressure to provide products free of biocides, volatile organic compounds (VOCs) and other additives. Meeting these requirements without compromising coating performance is an ongoing challenge for colorant producers. VOC-free colorants, while more environmentally friendly, come with their own set of challenges, including mold and bacteria formation, sedimentation, extended colorant drying times and the necessity for additional thickening in the waterborne coatings system.
Various challenges of traditional VOC-free colorants can also extend to the point-of-sale equipment systems used for dosing. These systems can lead to extended downtimes due to colorant changes, increased colorant consumption driving up ownership costs, issues like mold formation, tube clogging and tip drying, as well as syneresis-related problems. These obstacles can cause significant and untimely delays for coatings companies, result in higher ownership costs, and ultimately increase the carbon footprint within the supply chain.
To address these challenges, Vibrantz Technologies developed a novel breakthrough technology, a high-performing and sustainable solution that revolutionizes the colorant tinting process. As the architectural waterborne coatings industryâs first and only volumetrically dosed tinting system of solid colorants designed for use in architectural and industrial waterborne paint applications, this technology offers several key sustainability benefits, many performance enhancements, and a decrease on the carbon footprint of traditional liquid colorants!
This patented technology has an improved sustainability profile compared to traditional tinting systems. The solid colorants are formulated without biocides, VOCs or extra additives, and will not dry out, thicken or cause sediment. Made with 100% recyclable packaging, this technology reduces overall waste and doubles the colorant shelf life from two to four years!
As a solid, the product lessens the intricacy and wear associated with liquid tinting, reducing the complexity of machinery and minimizing the need for recurring maintenance. Additionally, it eliminates purging cycles and maximizes ease of use, lowering the need for spare parts, additional trips from technicians and overtime helping to decrease our carbon footprint.
The uniformed shape and narrow particle size of each solid colorant offers superior tinting accuracy and less mistints. The need for fewer additives minimizes the impact on important properties of the end-use paint. Lowering the active ingredients also decreases the impact on viscosity drop, increases blocking resistance and allows the waterborne coatings binder systems to maintain its film properties.
This innovation is uniquely positioned to provide sustainability, tinting efficiency and enhanced performance advantages. With the integration of cloud technology to drive dispensing, matching and analytics, this innovative technology revolutionizes the architectural waterborne coatings industry and offers precise control over the entire tinting process.

Novel Polyisocyanates for Flexibilizing Polyurea Coatings
Polyisocyanates are widely used as building blocks together with polyols to form polyurethanes. These materials find use in a variety of applications due to their excellent durability, and mechanical properties. However, a large number of polyurethane formulations are solvent-borne and decreasing the amount of Volatile Organic Compounds (VOC) can be challenging. Solvent-free technologies are one solution. Among these, polyurea formulations (reaction of polyisocyanates with polyamines instead of polyols) are of high interest, especially polyaspartic ester formulations.
The reaction of polyamines with polyisocyanates is much faster compared to polyols. This generally improves the drying and curing time but can unfavorably impact other parameters such as the pot life of the formulation. One additional issue with polyurea formulations can be a high level of brittleness.
Fortunately, the properties of such formulations can be fine-tuned by adjusting the starting materials. Different polyaspartic ester resins can be used having different reactivities and levels of rigidity, however it possible to further optimize these formulations by also adjusting the type of polyisocyanate used.
This presentation will look at the benefits that can be achieved through the use of novel polyisocyanate technologies, particularly with regard to improving the flexibility and pot life of the final coating.

100% Active Dispersants for Aqueous and Non-Aqueous Coatings
The latest developments in 100% solids, zero VOC dispersants allow for excellent handling properties while still maintaining exceptional pigment and particle dispersion capabilities. The unique combination of novel polymer-chain technology and innovative pigment anchor chemistries enable easy handling at 100% solids with greater formulation flexibility and universality than lower solids dispersants. The hazards of solvents are removed, and transport and manufacturing efficiency are improved, reducing overall carbon footprint and improving ease of use. Novel 100% active aqueous dispersants are flowable at room temperature and benefit from simpler regulatory and labelling scrutiny through elimination of biocides. In non-aqueous and UV-cure applications, 100% active dispersants can help reduce overall VOC, broaden dispersant compatibility with solvents and monomers, and allow for greater formulator flexibility. Strong color performance can be achieved in pigment dispersions with equal or better performance compared to lower solids alternatives. This presentation will highlight recent advances in 100% active hyperdispersant technology for aqueous and non-aqueous coatings and the performance thereof.

Easy to Process: New Silica Matting Agent for Energy Curable Coatings
Author: Dr. Ziniu Yu, Technical Service Manager â Coatings, W. R. Grace
With the changes of peopleâs taste in furniture and flooring aesthetics, low-gloss energy curable coatings are becoming popular in the coatings industry. However, the traditional silica matting agents in the energy curable coating can significantly increase the viscosity of the formulation, which may limit the flexibility of formulation development at formulators. In addition, the viscosity increase may force the convertors to change their application process to adapt to this viscosity by, for example, raising the application temperature during roller coating.
In this paper, a new silica matting agent with special organic treatment is introduced. It provides lower shear and processing viscosity compared to traditional matting agents, which allows the applicators to have larger bandwidth in processing the coatings system. In addition, excellent matting efficiency was observed when combined with smaller particle size matting agent in the formulation. The other performance features like chemical resistance, hardness and film clarity are investigated. With the rheological benefits and good chemical and physical performance, the newly developed silica matting agents are the ideal solution for 100% VOC-free energy curable coating systems.

Looking Beyond Performance Specifications to Capitalize on New Opportunities in Factory Applied Coatings
In today's world of factory applied coatings there are many challenges facing the coater. These can be anything from regulatory and permitting issues, cost of energy, loss of experience or reduced capital budgets preventing expansion to name a few. Adding to this, formulators as face many challenges. These could be a need to reduce the VOC in their formulation, use of less fossil and more bio-carbon or even particular parts of formulations being regulated away. All of these challenges have one thing in common. Meeting a coating performance specification will not address these challenges for the formulator no the end users.
For resin suppliers and coatings formulators to continue to offer products in the future they will need to do much more than just meet a performance specification. They will need to offer products that will meet some of the challenges of the end user has today as well as those which will come in the future.
This presentation will show how to find opportunities, in factory applied industrial coatings, which are not being addressed with a coating specification. It will show how particular coating attributes can bring additional value to the end user. This may be in speed, versatility, regulatory, or reducing layers. In particular this paper will concentrate on new water-based alternatives which bring additional value to the end user while maintain all of the current must haves for the application.

Stephanie Vanslambrouck*, Ligia Bardasu*, Laurent Desfontaines*
*EMCO-Inortech, Terrebonne, Canada
Epoxy membranes, with their remarkable mechanical strength, chemical resistance, and thermal stability, are gaining traction for diverse applications including coatings, insulation components, medical devices, and packaging. One key feature that enhances the adaptability of these sturdy materials is their ability to elongate significantly without rupture, a characteristic that is vital in applications demanding both flexibility and durability.
This paper explores the integral role of elongation in determining the performance of epoxy membranes. To delve deeper, we will modify the formulation by integrating a nonyl phenol-free and MEKO-free extender and/or plasticizers. Our study aims to offer a comparative analysis of how these product modifications impact the elongation properties of the membranes.
Furthermore, we will draw a detailed comparison between phthalate and phthalate-free plasticizers, shedding light on how each influences the performance and characteristics of the epoxy membranes. The insights gleaned from this research could potentially steer the design of more efficient and effectives applications of epoxy membranes.

Novel Resins and Formulation Approaches for Challenging Regulations
The US has set a goal of reducing carbon emissions by 50% compared to 2005 levels by 2030. According to American Coatings Association (ACA) publications, there are concerns for the future of exempt status of parachlorobenzotrifluoride (PCBTF) and tertiary butyl acetate (TBAC) solvents. Coating companies are facing a challenge to reformulate coatings with the existing resins, without the use of PCBTF and TBAC. Higher solids and optimal curing resins are needed to meet the demand of stringent VOCs, lower carbon emissions and ability to formulate without PCBTF and TBAC. Coating formulations play an equally important role with high solids resins.
In this paper we demonstrate the unique approaches and toolbox that a formulator can use based on recent advances in the areas of ultra-high solids resin technology and ways to formulate with identified key parameters. In our lab, we developed very high solids polyols ranging from 75% to 90% solids, that gave optimal curing and pot-life balance. The equivalent weight plays an important role in designing high solids resins as monofunctional moieties do not contribute to crosslinking and difunctional moieties give limited crosslinking. To compensate for the performance of higher solids resins, reactivity needs to be higher than the traditional resins. We demonstrate, using the toolbox, feasibility to formulate low VOC coatings with optimal performance. We also illustrate the importance of coatings formulation by showing the effect of type of solvents, and catalyst levels on pot-life, dry-time and film properties. Among these, selection of solvents and catalysts play an important role to achieve balance between pot-life and final property development without vitrification. Various conventional and advanced film properties are evaluated including weathering performance by Xenon, cure kinetics using IR spectroscopy and crosslink density and Tg, by Dynamic Mechanical Thermal Analysis (DMTA). A set of very high solid resins gives ammunition to coating industries to meet the challenging upcoming regulations.

New Biobased Versatile Binder for Architectural Coatings
A new versatile binder with 100%-biobased composition and -solids has been developed to enable our customers to formulate solvent-borne paints with lower VOC content and improved carbon footprint. In parallel, this polymer can be a surfactant free alternative to water-borne dispersions in water-based architectural coatings. For this development, Design of Experiments (DoE) was used to optimize key properties of the binder like color index, workable viscosity at 100% solids and different levels of biobased content.
In this paper, we present our polymer design approach and application results in formulation of architectural coatings comparing with standard binders.

To address those challenges raw material suppliers and coatings manufacturers are increasingly turning to water-based solutions of that require efficient, environmentally friendly emulsion technologies. The science behind key wax and silicone additive technologies to meet these needs will be presented.Â
Innovative technologies will be presented that utilize unique waxes, silicones, and wax â silicone hybrids. These additives are used to disperse pigments, reduce foam, and provide coating advantages including wetting and leveling, water and oil repellency, block resistance, water beading, scratch and abrasion resistance, haptic properties, and both slip and anti-slip performance. Â Novel coating additive features will be translated into specific advantages and benefits for coating formulators and end-users.

Polyaspartic coatings were developed about 30 years ago for coating steel, to prevent corrosion. Â The high-performance coating attributes led to expanding the utility through experimentation of this technology into other applications.Â
â˘Over the years, polyaspartic coatings have improved and can be expanded into applications that traditionally are dominated by epoxy and urethane systems. The reaction to produce a polyaspartic coating is between the polyisocyanate (NCO) and an amine-functional resin (NH).Â
â˘The main challenge with polyaspartic technology is that working time is significantly reduced due to its fast reaction rate. The development of a polyaspartic coating that retains all the high-performance properties yet, provides sufficient working time is very desirable in the market.Â
â˘To meet this need, the use of an aliphatic polyisocyanate based on hexamethylene diisocyanate (HDI), and blends at different percentages were formulated and found to reduce the reaction rate. The polyisocyanate and blends were then compared with other equivalent products currently in the market.Â

Predicting Defoamer Performance in Different Waterborne Coating Formulations
What is the usual procedure for selecting a defoamer for a new waterborne coating formulation? For many companies, the procedure appears to be as follows: try the defoamers that you currently use; if these donât work then try samples in the lab, ask a colleague or friend or, maybe, ask a supplier. This approach makes
good sense when working with formulations that are similar, as defoamers will usually give consistent performance in similar formulations. However, when these tried and trusted defoamers donât work, the chemist has the frustrating task of trying to find a suitable product. There is a truism in England that goes, âif all else fails, read the instructions,â however, defoamers donât usually come with instructions. Wouldnât it be nice if they did?
 Defoamers can have a critical impact on the performance of a coating but finding the right defoamer for a given application can be time consuming and frustrating. Defoamer performance is controlled by the chemistry and formulation of the defoamer but it is also significantly affected by many variables in formulation, application and manufacture. These variables include type of agitation, application method, coating ingredients and chemistry pigment volume concentration, coating viscosity, application thickness, and drying time. However, based on the chemistry and formulation of a defoamer, it is possible to predict its performance in different types of coatings and applications. This paper will discuss how the design of defoamers can affect performance in different coating formulations and how coating formulators can more quickly find the optimal defoamer for their specific applications.

Incorporation of Nonionic Reactive Surfactants and Resin Stability
Replacing conventional surfactants with reactive surfactants is not a straightforward process.
How the surfactant is added, the ratio of anionic to nonionic, the reaction conditions, and the ratio of
surfactant reacted into the polymer backbone, and reaction temperature all affect the emulsion
properties and coatings performance. These properties include scrub resistance, grit formation, shear
stability, and particle size to name a few.
The reactive surfactant was designed to react with the main monomers used in emulsion polymerization
and exhibit surface activity similar to that of conventional surfactants. The optimized formulation and
process allowed the incorporation of 70-85% of the reactive nonionic surfactant into polymer. Semi-gloss
paints formulated with the polymer made with reactive surfactant had up to 90% higher scrub resistance
