Superiority

vp/va copolymers with different rations of n-vinylpyrrolidone to vinyl acetate,soluble in most organic solvents.which exists in powder,water solution form.vp/va compolymer forms hard,water-removable and glossy films,it has excellent compatibility with many plasticizers and modifiers,an the hydroscopicity decreases in proportion to the ration of vinyl acetate.

vp/va copolymers are the excellent choice as film forming agent and hair-styling agent,which are suitable for fourmulations which used as film forming and viscosity modification,especially in hair styling products, such as hair gels,aerosol gas sprays,wet look sprays.

Details
