Application
UV ABSORBER HOSORB-UV1 is a high efficient anti-ultraviolet additive. It is widely used in adhesives, polyurethane, foam and other materials. Because of its excellent absorption property, the ultraviolet radiation in 240-340nm is effectively absorbed and the ultraviolet radiation in the 300-330nm is nearly absorbed completely. Its anti-ultraviolet effect is 1.1-1.4 times as efficient as the UV absorbers of benzophenone or benzotriazole types.
UV1 has good effect on the polymer system and it has good compatibility with the resin. The anti-yellowing effect is excellent. Its effect is superior to the other UV agent for PU. It is widely used in PU foaming, PU coating, PU leather, PU board and resins etc.
