POLYVINYL CHLORIDE/POLYVINYL ACETATE CO-POLYMER

A tough durable polymer made from vinyl chloride (80-95%), vinyl acetate, and small amounts of other monomers that provide solubility and adhesion. Stabilizers are required to prevent decomposition by light and heat. These polymers are used in lacquer-type coatings. They have been particularly valuable for immersion service as ship hull coatings or municipal water tank linings. These coatings usually do not meet VOC requirements due to the large amount of solvent needed to dissolve the polymer, so their use has been greatly restricted.
