用途

(Application)

紫外线吸收UV-53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PEPVCPPPSPC、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 (This product is an antioxidant with good performance, capable of absorbing the UV radiation of 240-340 nm wavelength with the characteristics of light color, no toxicity, good compatibility, small mobility, easy processing etc. It is widely applied to PE, PVC, PP, PS, PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde, varnish of alcohol and acid, polyurethane, acrylate, expoxide etc. Its dosage is 0.1%-0.5%)
