UV absorber uv-531 is an effective anti-aging agent with excellent performance. It can absorb ultraviolet light of 240-340 nanometers. It has the characteristics of light color, non-toxic, good compatibility, small migration and easy processing. It has the greatest protective effect on the polymer, and helps to reduce the color, while delaying yellowing and retarding the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and vinyl acetate. And for dry phenolic and alkyd varnishes, polyurethane, acrylic, epoxy and other air drying products and automotive paint, powder coatings, polyurethane, rubber products, to provide them with a good light stability. The dosage of 0.1% to 0.5%. Packing: 25kg carton or carton packing.
