2-(2H-Benzotriazol-2-yl)-4,6-ditertpentylphenol Chemical Properties,Usage,Production

Consumer Uses

This substance is used in the following products: coating products, air care products, adhesives and sealants, lubricants and greases, polishes and waxes and washing & cleaning products. Other release to the environment of this substance is likely to occur from: indoor use (e.g. machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners), outdoor use, indoor use in close systems with minimal release (e.g. cooling liquids in refrigerators, oil-based electric heaters) and outdoor use in close systems with minimal release (e.g. hydraulic liquids in automotive suspension, lubricants in motor oil and break fluids).

Properties

UV-328 has a melting point of 80-86 °C, a vapor pressure of 4,6·10−5 Pa (20 °C) and a water solubility of < 0,001 g·l−1 (20 °C).

Description

UV-328 (2-(2H-Benzotriazol-2-yl)-4,6-ditertpentylphenol) is a chemical compound that belongs to the phenolic benzotriazoles. It is a UV filter that is used as an antioxidant for plastics.

Uses

2-(2H-Benzotriazol-2-yl)-4,6-di-tert-pentylphenol is an ultraviolet light absorber (UVA) of the hydroxyphenylbenzotriazole class, which imparts outstanding light stability to plastics and other organic substrates.

Uses

UV-328 is a class of benzotriazole derivatives that can potentially be used as corrosion inhibitors in heat resistant fluids in aircraft, brake fluids in automobiles and for other industrial cooling systems.

Application

UV-328 is a light stabilizer for a variety of plastics and other organic substrates. Its use is recommended for the stabilization of styrene homopolymers and copolymers, acrylic polymers, unsaturated polyesters, polyvinyl chloride, polyolefins, polyurethanes, polyacetals, polyvinyl butyral, elastomers and adhesives.It protects polymers and organic pigments from UV radiation and helps maintain the original appearance and physical integrity of moldings, films, sheets and fibers during outdoor weathering. The application concentration is 0.1-1 %.UV-328 is recommended for applications such as automotive coatings, industrial coatings, commercial inks such as wood stains or do-it-yourself inks.

General Description

2-(2H-Benzotriazol-2-yl)-4,6-di-tert-pentylphenol (UV-328) is an ultraviolet (UV) stabilizer with a phenolic group connected to the benzotriazole structure. These phenolic groups facilitate the absorption of UV light. UV-328 is mainly used in as a light stabilizer for coating and as an additive for industrial polymers.
