In the coatings industry, the concept of sustainably is becoming increasingly important, whether to meet regulatory requirements or growing customer and consumer expectations.1,2 Sustainability is also a significant driver for coatings innovations.3,4,5
Novel Hydrolytically Stable Silane Additives for Improving the Performance of Waterborne Acrylic Roof Coatings
As global environmental regulations continue to tighten restrictions on coatings containing volatile organic compounds (VOCs), the need for hydrolytically stable additives in waterborne coatings has never been greater.
Demonstrating a commitment to sustainability is essential for a chemicals-based company’s success. Investors, customers, and consumers expect companies to implement environmentally sustainable changes while assuming the social responsibility of managing consumption and production.
Liquid ethylene propylene diene rubber (L-EPDM) has been known in the coatings industry for many years. These elastomers have found utility in ambient cure liquid-applied roof coatings. These resins, formulated into waterborne liquid coatings, may be cured with peroxides, metal driers, or UV radiation and can be used in ambient maintenance coatings for flat or low-slope roofs.
Durability remains a prime driver of exterior coating purchases in all market segments where coatings are exposed to severe conditions, including wood decks, all types of siding, industrial metals that are more susceptible to damage in harsh environments, and many others.
Car buyers around the world prefer neutral colors by a large margin and have done so many years. That trend is expected to persist for the next several years as well, although colors should make a small comeback.
A new application of Michael Addition (MA) chemistry was recently explored and developed for use in industrial flooring. Historically, MA was not applied in protective coatings due to the extremely fast reactivity which resulted in poor appearance and unacceptably short pot life.
The move to waterborne coatings has been occurring for many years. Water-based technologies dominate the architectural market and have done so for some time. While it has taken longer, they have now also made significant inroads in the industrial sector. Performance in many industrial applications has markedly improved. Even so, there is more work to be done.
Achieving Class A appearance over fiber-reinforced substrates can be challenging. We discuss the evolving measurements used to characterize topcoated surface appearance. The influence of carbon fiber on the surface appearance of a thermoplastic resin-transfer-molding (RTM) substrate is related to differences in thermal expansion within the substrate.
Radiation-cured coatings continue to experience moderate growth and find expanded applications. These coatings have the ability to increase productivity while offering enhanced environmental compliance and improved physical performance. They hold the potential to offer innovative solutions and the instruments used to produce them are becoming more advanced and cost-effective.
