It is understood that the light stabilizer UV-770 is a high-efficiency low molecular weight hindered amine light stabilizer, which works through free radical reaction. It is white granular with a melting point of 81.00 -86.00℃, soluble in benzene, chloroform, methanol, ethanol, ether and other organic solvents, insoluble in water.
Light stabilizer UV-770 has a wide range of uses:
Light stabilizer 770 is widely used in polypropylene woven packaging bags, polypropylene tarpaulins, Indoor and outdoor coatings, furniture paints, plastic runways, and road construction.
Suitable for adding to various polymers requiring high light stability, including polypropylene, high-density polyethylene, ABS resin, PMMA, SAN, PVC, nylon, polyester, polyacetal, etc. Especially suitable for PP, TPO, styrene polymers (HIPS, SAN, ABS, ASA), polyamide, polyurethane, polyacetal, elastomers, adhesives and seals, etc., and also suitable for thin products such as PP film and tape.
Used together with antioxidants, it can improve heat resistance. It also has a synergistic effect with UV absorbers, which can further improve the light stabilization effect. Used together with antioxidants, it can improve heat resistance. It can also be used with UV absorbers. UV absorbers also have a synergistic effect and can further improve the fire resistance effect.
