Hydroxyl-Modified Vinyl Chloride/Vinyl Acetate Terpolymers
Hydroxyl Modified Vinyl Chloride, Hydroxyl Modified Vinyl Acetate Terpolymers
Grade MVAD: It is white powder, ketone soluble with colorless, transparent solution and has excellent adhesion on PET, resin primer, paper, PVC, ABS pre-treatment of PE and OPP. It is often used
with other film-forming material in order to improve the coating performance, and enhance paint adhesion、flexibility、tenacity、hardness
and chemical resistance. The hydroxyl functional group permits crosslinking reactions for thermoset,obtaining excellent chemical and water resistance.
