Modified polycarboxylic acid copolymer ammonium salt dispersant HY-165A

Product Overview:

HY-165A is a hydrophobically modified polycarboxylate copolymer ammonium salt with ABA structure. Because its molecular backbone has both a hydrophobic olefin group and a carboxylic acid group with a regular ABA structure, its molecule can take into account both hydrophobicity and dispersion, and is a weather-resistant dispersion additive with excellent performance. The polymer can effectively improve the water resistance and stain resistance of the paint film, and can effectively play a role in the dispersion of non-polar pigments and fillers, effectively reduce the amount of polyoxyethylene modified dispersants, and save the formulation cost.
