Hydroxyl Modified Vinyl Chloride/Vinyl Acetate Terpolymers PG-HC
Hydroxyl-Modified Vinyl Chloride/Vinyl
Hydroxyl Modified Vinyl Chloride, Hydroxyl Modified Vinyl Acetate Terpolymers
New grade PG-HC: It 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.
