Description

2-Hydroxy-4-n-Hexyloxybenzophenone is a specialized organic compound belonging to the benzophenone class, widely recognized for its efficacy as a light stabilizer. Its core value lies in its ability to absorb and dissipate ultraviolet (UV) radiation, thereby protecting materials from photodegradation and extending their functional lifespan. This product is essential for manufacturers in the polymer, coatings, and personal care industries who require high-performance UV protection for their formulations.

Application

• Primary UV absorber and light stabilizer in plastics and polymers, including polyolefins (PP, PE), PVC, and engineering resins.
• Critical additive in protective coatings, paints, and varnishes to prevent yellowing, cracking, and loss of gloss caused by sunlight exposure.
• Key ingredient in sunscreen and personal care formulations (cosmetics, skin creams) to provide broad-spectrum UVA/UVB protection.
• Stabilizing agent for adhesives, sealants, and rubber products to enhance weatherability and durability.
• Used in the production of specialty films and packaging materials that require protection from UV-induced degradation.
• Functional additive in industrial finishes and automotive coatings to maintain color and integrity under harsh environmental conditions.
