  Hydroxyl-Modified Vinyl Chloride/Vinyl Acetate Copolymers VAH
  E MAIL: NANCYGAO98 AT YAHOO DOT COM
  A high molecular weight, partially hydrolyzed vinyl chloride/vinyl acetate resin, made in a two-step process, having a composition of approximately 90 percent vinyl chloride, 4 percent vinyl acetate, 6 percent vinyl alcohol, with a hydroxyl content of approximately 2.3 percent. VAH has excellent adhesion on PET, resin primer, paper, PVC, ABS, pre-treatment of PE and OPP. VAH 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.
