Richvin 765 is a liquid light stablilzer belonging to the class of hindered amine light (HALS) stabilizer. Richvini 765 is recommended for the light stabilization of polyurethanes, becasue of its good solubility in organic solvents, such as polyols and DMF. The performance of Richvin 765 in polyolefins and PU is camparable with Richvin 770.
Richvin 770 excellent compatibility with most polymers. It can be incorporated into the polymer in a conventional way. it shows synergistic effect by the combined with benzotriazole or benzophenone t
