YS-770 is a hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It is recommended to be used in PP, EPDM, PS, HIPS, ABS, SAN, ASA and PUR and is also effective in PA and polyacetals. It provides excellent light stability for thick sections and films in the recommended substrates. The benefit of using YS-770 is its high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. Compared to conventional UV-absorbers, the effectiveness of YS-770 is less dependence on the polymer's thickness. For this reason the use of YS-770 also provides good light stability in articles with higher specific surface, e.g. films and tapes.
