It has the greatest protective effect on the polymer, and helps to reduce the color, while delaying yellowing and blocking the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, plexiglass, polypropylene fiber and vinyl acetate. And for the dry phenolic and alkyd varnish, polyurethane, acrylic, epoxy and other air drying products and automotive finishing paint, powder paint, rubber and other products, they provide a good light stability effect.
