Applications

UV absorber 928 is a benzotriazole UV absorber suitable for high-performance coatings. It has the characteristics of high temperature resistance and good light stability and is particularly suitable for coating systems exposed to high temperatures or extreme environments for a long time. The effect of 928 combined with hindered amine light stabilizers is more ideal. The combination can provide better protection for coatings, including preventing the coating from discoloration, loss of gloss, cracking, and separation from the substrate.

Storage

UV absorber 928 is stable in nature and has no special requirements; pay attention to moisture-proof and avoid high temperature.

Recommended Concentrations

0.05-0.3% (the specific amount to be added is subject to the actual application of the customer).
