What is tinuvin 292 CAS 82919-37-7？

tinuvin 292 CAS 82919-37-7 is a liquid light stabilizer that can extend the outdoor exposure time of various plastics and coatings. During the processing, it does not produce an odor with polymers or affect the original color of the material. It is not easily volatile during high-temperature processing and has superior polymer compatibility.

UV 292 is a light stabilizer composed of a mixture of two esters, which has a synergistic effect with benzotriazole UV absorbers and can effectively prevent coatings from bursting and surface peeling under sunlight exposure.

应用

UV 292 is mainly used in organic polymers such as polyethylene, PVC, PVB, ABS resin, polyester, and polyurethane. Especially suitable for polyurethane, as Light stabilizer 292 has good solubility in solvents.

UV 292 is more suitable for automotive coatings and industrial coatings. Wood paint, light hardening industrial coatings, PU resin, adhesives and other plastics.

UV 292 has a good synergistic effect when used together with benzotriazole type UV absorbers, which can significantly improve the weather resistance of the product, much better than using UV absorbers alone. By adding appropriate dispersants, Light stabilizer 292 can be well suited for water-based coatings.
