Description

2-Benzotriazol-2-Yl-4-Methyl-Phenol is a high-performance organic compound belonging to the benzotriazole class of ultraviolet (UV) light absorbers. It is valued for its exceptional ability to protect materials from photodegradation by absorbing harmful UV radiation and dissipating the energy as heat. This product is essential for manufacturers in the polymer, coatings, and personal care industries seeking to enhance the durability, color stability, and lifespan of their formulations against sunlight exposure.

Application

• Polymer Stabilizer: A key additive in plastics (e.g., polyolefins, PVC, polycarbonates) and synthetic fibers to prevent yellowing, embrittlement, and loss of mechanical properties caused by UV light.
• Coatings & Paints: Used in automotive, industrial, and architectural coatings to maintain gloss, prevent chalking, and protect the underlying substrate from UV-induced damage.
• Adhesives & Sealants: Incorporated to ensure long-term performance and adhesion strength by preventing polymer backbone breakdown from outdoor exposure.
• Personal Care Products: Acts as a UV filter in sunscreen formulations and cosmetic products to protect the skin from UVA and UVB radiation.
• Wood & Surface Protection: Applied in stains, varnishes, and treatments for outdoor wood and composite materials to reduce weathering and color fade.
• Agricultural Films: Added to greenhouse and mulch films to extend their functional life by stabilizing the polymer against solar radiation.
