Characteristics and uses:
紫外线吸收剂是一种性能卓越的高效防老化助剂, 能吸收240-340纳米的紫外光, 具有色浅、无毒、相容性好、迁移性小、易于加工等特点。它对聚合物有最大的保护作用, 并有助于减少色泽, 同时延缓泛黄和阻滞物理性能损失。它广泛用于PE、PVC、PP、PS、PC、有机玻璃、丙纶纤维和乙烯醋酸乙烯酯等方面。而且对于干性酚醛和醇酸清漆 类、聚氨酯类、丙烯酸类、环氧类和其它空气干燥产品及汽车整修漆、粉末涂料、聚氨酯、橡胶制品等, 为它们提供了良好的光稳定效果。用量0.1%-0.5%。
UV absorber is an excellent anti-aging additive with excellent performance. It can absorb ultraviolet light of 240-340 nm, and has the characteristics of light color, innocuity, good compatibility, small migration and easy processing. It has the greatest protective effect on the polymer and helps to reduce the color, retard the yellowing and block the loss of physical properties. It is widely used in PE, PVC, PP, PS, PC, organic glass, polypropylene fiber and vinyl acetate vinyl ester and so on. And for dry phenolic and alkyd varnish, polyurethane, acrylic, epoxy and other air drying products and automotive finishing paint, powder coatings, polyurethane, rubber products and so on, to provide them with good light stability effect. The dosage is 0.1%-0.5%.
