Characteristics and Application: UV Absorber BP-6 is an excellent and efficient anti-aging additive that can absorb UV light from 270 to 400 nanometers. It has the characteristics of light color, non-toxic, good compatibility, small migration, and easy processing. It has the greatest protective effect on polymers and helps to reduce color, while delaying yellowing and blocking physical property loss. It is used in PE, PVC, PP, PS, PC, and other fields. And for dry phenolic and alkyd varnishes, polyurethane, acrylic acid, epoxy, and other air dried products, as well as automotive repair coatings, it provides good light stability effects for them. Dosage 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 barrels lined with plastic bags, with a net weight of 25kg/barrel, and can also be designed according to customer requirements.
