Application:
Ultraviolet absorber BP-6 is a kind of high-efficiency anti-aging additive with excellent performance. It can absorb ultraviolet light of 270-400 nanometers. It has the characteristics of light color, non-toxicity, good compatibility, small migration and easy processing. It provides maximum protection to the polymer and helps reduce color while retarding yellowing and retarding physical property loss. It is used in PE, PVC, PP, PS, PC, etc. It also provides good light stabilization for dry phenolic and alkyd varnishes, polyurethanes, acrylics, epoxy and other air-drying products and automotive refinishing paints. The dosage is 0.1%-0.5%.
