  UV-320 is a highly effective light stablizer for a variety of plastics and other organic substrates including unsaturated polyesters, PVC and PVC plastisol. Good results are also expected when UV-320 is used in polycarbonates, polyurethanes, polyamides, synthetic fibers, particularly those with a polyestcr, skyd. epoxy or isocyanate resin base. UV-320 features strong UV absorption excellent compatibility in a varicty of substrates and low volatility and protects polymers, as well as organic pigments from UV radiation hclping to preservc the original appearance and physical integrity of molded articles, films, sheets and fibers during outdoor weathering, UV-320 is slightly more discoloring than convention UV absorbers.
