Description

2-(2H-Benzotriazol-2-Yl)-5-tert-Butyl-4-Hydroxyphenylpropionic Acid 1,6-Hex is a high-performance benzotriazole derivative, specifically engineered as a light stabilizer and ultraviolet (UV) absorber. This compound is critical for protecting polymers and coatings from photodegradation, thereby extending product lifespan and maintaining aesthetic properties. It is an essential raw material for manufacturers in the plastics, paints, and advanced materials industries seeking to enhance the durability of their formulations against environmental stress.

Application

• Polymer Stabilization: Primary use as a UV absorber and light stabilizer in polyolefins (e.g., PP, PE), PVC, polycarbonates, and other engineering plastics to prevent yellowing and embrittlement.
• Coatings and Paints: Incorporated into automotive coatings, industrial paints, and wood finishes to protect against color fade and gloss loss caused by sunlight exposure.
• Adhesives and Sealants: Used to improve the weatherability and long-term performance of high-value adhesive and sealant formulations.
• Agricultural Films: Added to greenhouse and mulch films to stabilize the polymer matrix against solar UV radiation, extending functional service life.
• Synthetic Fibers and Textiles: Applied in the production of UV-resistant fibers for outdoor apparel, awnings, and geotextiles.
• Advanced Material Additive: Serves as a functional additive in specialty composites and masterbatches requiring enhanced photostability.
