This article examines non-fluorinated surfactant and defoamer strategies for maintaining wetting, defect control and performance in waterborne coating formulations.
Abrasion is one of the most important defects that deteriorates the durability of coatings. The goal of the research presented in this article was to achieve a good understanding of the effects of coating additives on the abrasion resistance of waterborne coatings.
Polyester-based adhesion promoters (PEAPs) are a series of modified UP resins that can partially replace the main binders in coatings formulations to improve their adhesion to difficult substrates.
The use of ambient-curing silicone resins shows a good alternate option to formulate high heat-resistant coatings compared to the traditional oven-curing or ambient-drying silicone resins.
By understanding how additive performance can be affected by formulation change, formulators can identify potential problems and work with their suppliers to find answers faster.
A series of modified siloxane defoamers has been developed that offers a controlled range of defoaming strength and compatibility relative to each other.
