Usage |
Ultraviolet absorber BP - 6 is a kind of anti-aging additive with remarkable effective performance. It absorbs 270 to 400 nanometers of ultraviolet light, with features of light color, non - toxic, good compatibility, small migration, easy to process. It has the greatest protective effect on the polymer, and helps reduce color, while delaying yellowing and blocking physical property loss. It is used for PE, PVC, PP, PS, PC, etc. And for the dry phenolic and alkyd varnish class, the polyurethane class, the acrylic class, the epoxy class and other air drying product and the automobile repair paint, it has provided the good light stability effect for them. Dosage: 0.1% to 0.5%.
