Description

Benzeneethanol, 3-(2H-Benzotriazol-2-Yl)-4-Hydroxy- is a specialized organic compound belonging to the benzotriazole class of ultraviolet (UV) light absorbers. This chemical matters for its exceptional ability to protect polymers, coatings, and other materials from photodegradation, thereby extending their service life and maintaining their aesthetic and mechanical properties. It is primarily needed by formulators and manufacturers in the plastics, paints, and advanced material industries seeking high-performance, light-stable additives.

Application

• As a highly effective UV absorber and light stabilizer in engineering plastics and polymers (e.g., polycarbonate, PET, PVC).
• To provide long-term weatherability and color retention in automotive coatings, industrial paints, and wood finishes.
• As a key additive in photostabilization packages for agricultural films, packaging materials, and synthetic fibers.
• For the protection of adhesives, sealants, and elastomers from UV-induced cracking and loss of elasticity.
• In the formulation of cosmetic and personal care products requiring UV filter properties (subject to regional regulatory approval).
• As a research chemical in the development of new photostabilizers and functional materials.
