Application: Cosmetic Industry: PVP A series products act film-former and hair-fixing agent in cosmetics. Their hygroscopicity decrease with the increasing of the proportion of vinylacetate in the copolymer. Other industries: It performs very well in remoistenable adhesive, adhesives for paper and coating. It can be used as viscosity-enhancing agent for printing ink a protecting aloud for lent-protecting chemicals.
