Polyvinyl alcohol (PVA) is a synthetic polymer that is water-soluble. It is made by the polymerization of vinyl acetate, followed by the hydrolysis of the resulting polymer. PVA has a wide range of applications due to its excellent film-forming and adhesive properties, as well as its biocompatibility and non-toxicity.
PVA 2699 can be used as emulsion stabilizer because PVA 2699 has a very low surface tension that can stabilize PVAC colloid particles forming aqueous emulsion but not condensation deterioration; also can be used as adhesive, in coating construction and textile industry.
