film former agent China VP/VA Copolymer,PVP/VA 64 Powder,PVP/VA 73W,PVP/VA 64W Detail:

VP/VA Copolymers with different rations of N-Vinylpyrrolidone to Vinyl Acetate,soluble in most organic solvents.Which exists in powder,water solution and ethnol solution form. VP/VA Copolymers’ aqueous solutions are non-ionic, neutralization not required, Resultant films are hard, glossy, and water-removable; Tunable viscosity, softening point and water sensitivity depending on VP/VA ratio; Good compatibility with many modifiers, plasticizers, spray propellants and other cosmetic ingredients,and the hydroscopicity decreases in proportion to the ration of Vinyl acetate.
