Application:
It is a highly effective radical scavenger that protects organic polymers against degradation caused by exposure to ultraviolet radiation. Light Stabilizer 770 is widely used in a variety of applications including polypropylene, polystyrene, polyurethanes, ABS, SAN, ASA, polyamides and polyacetals. Light Stabilizer 770 is high effectiveness as a light stabilizer makes it well suitable for applications in both thick section and films, independent of the thickness of the articles. Combined with other HALS products, Light Stabilizer 770 displays strong synergistic effects.
