BLS 1710 2-(2H-Benzotriazole-2-yl)-4-methylphenyl 2440-22-4 Mayzo Light stabilizer / UV-absorber >> Benzotriazole Coatings Insoluble in water Insoluble in methanol Insoluble in ethanol Slightly soluble in methylene chloride BLS™ 1710 Ultraviolet Light Absorber Antioxidant and Thermal Stabilizer benzotriazole type ultraviolet light absorber (UVA), imparting good light stability for plastics and other organic polymers. Protects polymers as well as organic pigments from UV radiation helping to preserve the original appearance and physical integrity of engineered plastics, elastomers, PVC, adhesives, and polyurethanes during outdoor weathering. 2-(2H-Benzotriazole-2-yl)-4-methylphenyl Applications: features a strong absorption of ultraviolet radiation in the 300-400 nm region. It has a high degree of photostability as its characteristics and structure are unchanged over long periods of light exposure. Provides ultraviolet protection in a wide variety of polymers including styrene homo- and copolymers, engineering plastics such as polyesters and acrylic resins,polyvinyl chloride, and other halogen containing polymers and copolymers, acetals and some cellulose esters. Elastomers, adhesives, polycarbonate blends, polyurethanes and epoxy materials Advantages: Strong absorption of ultraviolet radiation in the 300-400 nm region High degree of photostability Thermally stable to processing temperatures as high as 600°F Excellent resistance to oxidizing and reducing agents used in polymerization and curing Imparts little or no initial color to substrates Does not discolor during light or heat aging Exhibits antioxidant and thermal stabilization properties Has low oral and dermal toxicity Synergistic performance with other stabilizers BLSÒ 1710 Ultraviolet Light Absorber BLS 1710 is a benzotriazole type UV absorber suitable for use in many plastics, coatings, rubber, adhesives, and organic polymers. Characterized by its strong, broad-range UV absorption properties, BLS 1710 brings an excellent photostability to polymers against UV light exposure in many ways, including retarding color yellowing, preventing embrittlement and in maintenance of mechanical properties. Benzotriazole. Used as an ultraviolet light absorber (UVA) in many coatings. Provides good light stability for plastics, other organic polymers and organic pigments, thermal stability to processing temperatures as high as 600°F, very good resistance to oxidizing and reducing agents and little or no initial color to substrates.
