UV Stabilizer 770 is a 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.
Bis (2,2,6,6,-tetramethyl-4-piperidyl) sebacate
UV Stabilizer 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.
UV 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. Benefits or using UV Stabilizer 770 is high-stabilizing performance, particularly in PP thick sections. It has broad compatibility and can be easily dispersed.
Compared to conventional UV-absorbers, the effectiveness of UV Stabilizer 770 is less dependent on the polymers thickness. For this reason the use of UV Stabilizer 770 also provides good light stability in articles with higher specific surface, e.g. films and tapes.
Combined with other HALS UV Stabilizer 770is part of other synergistic blends, e.g.
UV Stabilizer 791
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 UV Stabilizer 770 in various substrates and for various applications is available upon request.
