Description

2-[3-(2H-Benzotriazol-2-Yl)-4-Hydroxyphenyl]Ethyl Methacrylate is a specialized monomer that incorporates a benzotriazole-based ultraviolet (UV) absorber directly into its molecular structure. This compound is engineered to provide exceptional light stability when polymerized, offering a permanent solution to UV degradation in advanced polymeric materials. It is a critical raw material for formulators and manufacturers in the coatings, adhesives, and specialty plastics industries who require high-performance, weatherable end-products.

Application

• UV-Stabilized Polymer Synthesis: As a reactive monomer for creating acrylic and methacrylic polymers with inherent, non-leaching UV protection.
• High-Performance Coatings: Formulation of automotive clear coats, industrial maintenance paints, and architectural coatings requiring superior gloss retention and resistance to yellowing.
• Advanced Adhesives & Sealants: Development of structural adhesives and sealants for outdoor applications where long-term durability under sunlight is essential.
• Optical Materials: Manufacture of lenses, optical films, and displays where clarity and resistance to UV-induced damage are paramount.
• Engineering Plastics & Composites: Modification of polycarbonate, polyester, and other engineering plastics to enhance their weatherability for automotive and construction components.
