LS 770 is recommended to be used in polypropylene, impact modified PP(TPO),EPDM, polystyrene, impact polystyrene ABS,SAN,ASA and polyurethanes and is also effective in polyamides and polyacetals. LS 770 is a low molecular weight hindered amine light stabilizer
that provides excellent light stability for thick sections and films in the recommended substrates. Benefits of using LS 770 is the high light-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed. The recommended concentrations range between 0.1% and 0.5%, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of LS 770 in various substrates and for various applications is available upon request.
