Applications: LS770 is recommended to be used in polypropylene,impact modified PP(TPO),EPDM,polystyrene,impact poystyrene,ABS,SAN,ASA and polyurethanes and is also effective in polyamides and polyacetals.

Features/Benefits: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 LS770 is the 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 LS770 is less dependent on the polymer's thickness.For this reason the use of LS770 also provides good light stability in articles with higher specific surface,e.g.films  and tapes.

Guidelines for use: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

Storage: Storeindry places under30ºC avoiding moisture and heat.

Package: 25kg/ carton(inner with plastic bag).
