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.
