Product Overview

UV Absorber UV-9 is a benzophenone-based ultraviolet absorber designed to protect materials from UV-induced degradation. It effectively absorbs UV radiation in the UV-B and short-wave UV-A range, helping to reduce discoloration, cracking, and loss of mechanical properties caused by sunlight exposure.

UV-9 is widely used in plastics, coatings, adhesives, rubber, inks, and specialty polymers where long-term light stability is required.
