Paint and Coating Resins & Polymers

RSS

This article examines the physical properties of polyurethanes and polyureas, their differences, and a technology review with benefits and drawbacks of sub-coating classes.

"We are proud to be a global leader in the energy curing industry," Wilfrid Gambade, iGM Resins CEO, said. "Our team will continue to focus on protecting our products and processes for our customers."

The coating and adhesive resins business line expects the additional production capacity to be ready as early as the second quarter of 2024, following the double-digit million-euro investment.

This month’s Formulating with Mike column continues the discussion on resins, with a focus on epoxy curing agents. When it comes to great adhesion, chemical resistance, and corrosion resistance, an epoxy is hard to beat. There are different epoxy curing agents, and each one provides different properties that can be suited for a wide variety of end-use applications. 

The recent Western Coatings Show in Las Vegas featured an exhibit hall packed with new technology for coatings formulators. This article offers a sampling of some of the raw materials and services showcased.

Through the incorporation of such unique benefits as leak-free operation and line-stripping capabilities, the eccentric-disc principle makes the pump extremely flexible, allowing the pumping of low-viscosity, high-viscosity, and highly abrasive materials within a single process — all with the same pump.

Naval Surface Warfare Center, Carderock Division has an ongoing project funded through the Office of Naval Research to develop a novel, corrosion-resistant poly(styrene-co-catechol) tie coat and adhesion promoter to improve CARC adhesion and performance to various composites, aluminum, and steel USMC ground vehicle surfaces.

For those looking to replace PFAS in their coatings formulations, this article discusses some experiments and data that show how organosilicones compare to PFAS compounds in critical performance criteria such as low surface tension/surface energy, COF, water repellency, oil repellency, stain resistance, and chemical stability.

This month’s Formulating with Mike column continues the focus on resins. Mike tests paints with APE-containing and APE-free emulsions for stability, particle size, and final paint quality.

This month’s Did You Know column discusses several classes of hybrid latex particles.
