| Characterization | Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer (HALS) for applications demanding particularly high light stability. It provides excellent light stability for thick sections but can also be used for articles with a high surface area such as films and tapes. |
| Applications | Light Stabilizer 770 is recommended to be used in polypropylene, impact modified PP (TPO), EPDM, polystyrene, impact polystyrene, ABS, SAN, ASA, polyurethanes, and is also effective in polyamides and polyacetals. |
| Applications |
Light Stabilizer 770 is a low molecular weight hindered amine light stabilizer that provides excellent light stability for thick sections and films in the recommended substrates. Benefit of using Light Stabilizer 770 is the high light-stabilizing performance, particularly in PP thick sections to protect the surface. It has broad compatibility and can be easily dispersed. Compared to UV absorbers, the effectiveness of HALS, like Light Stabilizer 770, is not dependent on the polymer’s thickness. For this reason the use of Light Stabilizer 770 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 1.0 %, depending on the substrate, processing conditions and application. The optimum level is substrate and application specific. Extensive performance data of Light Stabilizer 770 in various substrates and for various applications is available upon request. |
