Hydroxyl-Modified Vinyl Chloride/Vinyl Acetate Terpolymers EMP-PG-HC is white powder、ester soluble with colorless& transparent solution and has excellent solvent release、film-forming compactness、dispersibility,which mainly is used for combination with PU resin to improve flexibility、solvent release、film-forming compactness and hardness in coatings and ink;It is very good film-forming substance with low swelling property and low gas permeability when its paint film meet water, after its combination use with PU resin etc, its paint film has excellent flexibility、high-wearing feature scratch resistance、water resistance、alcohol resistance.
EMP-PG-HC is mainly used for application gravure plastics composite printing inks、wood coatings( e.g: matte coating、topcoat gloss etc)、UV primer、PE primer etc.
