A new wetting agent enhances wetting behavior, particularly in wood coatings. The innovative approach is based on a comparative evaluation of silicone-free and silicone-based surfactants, focusing on surface tension and contact angle.

This article discusses the basic characteristics of phyllosilicate thickeners, and provides an introduction to understanding their performance in formulations in order to use them to build the rheological properties of latex paints.

A novel polymerizable surfactant was developed and utilized to prepare latex polymers and resins through emulsion polymerizations. These polymers were then evaluated in PSA and architectural waterborne coating formulations. The results showed that the new surfactant almost fully reacted during the emulsion polymerization, and reduced or even eliminated the free surfactant migration during film formation.

A new fast-cure, high UV-resistant curing agent that addresses both performance and EHS gaps in the current market enables a rapid return to service and delivers coatings with exceptional aesthetics at ambient and low temperatures, outstanding carbmation and UV resistance, and extended working times.

Learn about scrub resistance tests for latex paints, their differences, and how they guide raw material selection for high-quality formulations.

This article discusses new developments in water-based UV-curable polyurethanes that offer much-improved 50 °C paint stability in clear, as well as pigmented coatings. It also discusses how these resins address the desired attributes of the coating applicator in increasing line speed through fast water release, improved block resistance, and solvent resistance off the line.

Explore the growth of water-based coatings, driven by advancements in resin, additive, and pigment technologies, and their increasing global adoption.

Covestro has introduced a waterborne and waterborne-UV family of high-performing resins for industrial coating applications such as wood furniture, cabinetry, and building products.  

Bio-surfactants are a promising alternative to chemical surfactants in the development of eco-friendly and high-performance coatings due to their bio-degradability, low toxicity, renewable feedstocks, and enhanced performance in various aspects of coatings formulations.

This study comprehensively evaluated novel, ultra-low-VOC 1K and 2K waterborne floor-coating systems designed to provide eco-friendly, lower-VOC alternatives to traditional solvent-based coatings. The materials employed in these innovative systems showed remarkable performance when subjected to industry-standard tests.
