Function:
1.Drometrizole has high efficient UV absorption function.
2. LOTSORB UV P has light stabilizing function.
3. Drometrizole has good compatibility and stability.
4. Odorless; insensitive to metal ions; non-flammable, non-explosive, non-toxic; almost non-absorption of visible light.
Application:
1. Widely used in plastics such as PVC, polypropylene, polyethylene, polystyrene, polycarbonate, ABS resin, polymethyl methacrylate and so on.
2. Used in coatings and inks, such as outdoor billboards, building exterior coatings, automotive coatings, etc., to improve their weather resistance.
3. Added to polyester, chlorinated polyester, acetate fiber, polyacrylonitrile and other fibers to improve the sun resistance of textiles.
4. It can also be used in epoxy resin, unsaturated resin, organic glass, polyurethane products, etc., to provide light stabilization protection for these products, and can also be used in plastic products in contact with food.
