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.
