PVA coating has good weather resistance, water resistance, does not swell when exposed to water, does not embrittle, is non-toxic, tasteless, and has the advantages of low price. In this field, the traditional varieties can only be used in the manufacture of forming plates. In the coating field, PVA with a higher degree of polymerization.
