Description

2-Octyl-2H-Benzotriazole CAS NO 112642-69-0 is a high-performance, substituted benzotriazole derivative widely recognized for its exceptional properties as a light stabilizer and corrosion inhibitor. Its primary value lies in its ability to absorb UV radiation and form stable complexes with metal ions, thereby protecting materials from photodegradation and corrosive attack. This makes it a critical additive for manufacturers in the polymer, coatings, and metalworking fluid industries seeking to enhance product longevity and performance under demanding environmental conditions.

Application

• Polymer Additive: Acts as a highly effective UV light stabilizer in plastics (e.g., polyolefins, PVC) and synthetic fibers to prevent yellowing, embrittlement, and loss of mechanical properties.
• Corrosion Inhibitor: Used in metalworking fluids, coolants, and industrial lubricants to protect ferrous and non-ferrous metals from oxidation and pitting corrosion.
• Coatings & Paints: Incorporated into automotive, industrial, and architectural coatings to improve weatherability, gloss retention, and color stability.
• Adhesives & Sealants: Enhances the durability and service life of adhesive formulations exposed to sunlight and outdoor environments.
• Personal Care Products: Serves as a stabilizer in sunscreen formulations and other cosmetic products that require protection against UV-induced degradation.
• Analytical Chemistry: Utilized as a chelating agent in specific analytical methods for the detection and quantification of metal ions.
