UV-1 使用方法

紫外线吸收剂 UV-1(101)是一种液态甲基丙烯酸苯酯紫外线吸收剂,能吸收 280-350 纳米的紫外线,吸收峰值为 308 纳米。300-330 纳米的紫外线几乎完全被吸收。

它具有相容性好、挥发性低、热稳定性好和吸收效率高等特点,易溶于聚酯多元醇、聚醚多元醇、环氧树脂和异氰酸酯。适用于粘合剂、灌封胶、滴晶胶,尤其适用于聚氨酯、硬质泡沫、软质泡沫、粘合剂、弹性体、织物涂料、聚氯乙烯、丙烯酸树脂。一般用量为 0.3-0.5%。

适用于:聚氨酯产品,如微孔泡沫、传统硬质泡沫、半硬质泡沫、软质泡沫、织物涂层、某些粘合剂、密封剂和弹性体,以及聚氯乙烯、丙烯酸树脂和其他具有优异光稳定性能的聚合物。
