Application

UV Stabilizer UV-1 is a highly effective anti-ultraviolet additive. UV stabilizer UV-1 is widely used in polyurethanes, adhesives and foams. Its anti-UV effect is 1.1 to 1.4 times that of benzophenone or benzotriazole. Uv-1 used in polymer system has good anti-ultraviolet effect, good compatibility with resin, excellent yellowing resistance, and has a wide spectrum of UV absorption bands.
