　　Features and uses: UV absorber BP-6 is a highly effective anti-aging aid with excellent performance, which can absorb ultraviolet light of 270-400 nanometers, with light color, non-toxic, good compatibility, small migration, easy processing, etc. Features. It has the greatest protective effect on the polymer and helps reduce color, while delaying yellowing and retarding the loss of physical properties. It is used in PE, PVC, PP, PS, PC, etc. And for dry phenolic and alkyd varnishes, polyurethanes, acrylics, epoxy and other air-drying products and automotive refinish paints, etc., they provide good light stabilization effect. The dosage is 0.1%-0.5%.

　　Storage and packaging UV absorber BP-6 is non-toxic, non-flammable, non-explosive, non-corrosive, and has good storage stability. Packed in cardboard drums lined with plastic bags, net weight 25kg/drum, or designed according to customer requirements.
