Use:
Ultraviolet absorbent UV-531 is a kind of high-effective anti-aging auxiliary with remarkable performance, can absorb 240-340 nanometers of ultraviolet rays. It has good characteristics, such as light color, nonpoisonous, good compatibility, slight transport property, easy processing and so on. It has the greatest protective action on the polymer, contributes to reducing the color and luster, it can suspend the yellowing and block physics performance loss at the same time. It is widely used in PE, PVC, PP, PS, PC, organic glass, polypropylene fiber and ethylene vinyl acetate. And it provides good light stability effect to the sorts of dry phenolic aldehyde and alkyd varnish, polyurethane, acrylic acid, epoxy and other air drying products and automobile rebuilt paint, powder coating, polyurethane, and rubber products.
