 Application:
PVP/VA series products play a good role as firm-forming and hair-fixing agent.It's hygroscopicicy decrease with increase in the proportion of vinylacetate in the molecular.This property is extremely used for PVP/VA as hair sprays and hair-set lotion.If used with PVPK30.the effect would be enbanced.
 Other Utility:

.Remoistenable adhesive and other adhesives for paper.
.Viscosity-enhancing agent and protecting colloid for printing ink .
.Emulsing agent and protecting colloid for plant-protecting chemicals and other dispcrsing systems.
.Binder in coating.
.Stabilizer,levelling agent,color stabilizer in printing and dyeing industry.
