In the chemical industry, the ability to protect materials from environmental degradation is paramount. Ultraviolet (UV) radiation poses a significant threat to a wide array of products, from plastics and coatings to adhesives. To combat this, UV absorbers are indispensable additives. Among them, UV Absorber 928 stands out as a highly effective and versatile solution. As a dedicated chemical manufacturer and supplier, we aim to provide clear insights into its properties and applications for procurement professionals and R&D scientists.

UV Absorber 928, identified by its CAS number 73936-91-1, is a hydroxyphenyl benzotriazole derivative. Its molecular formula is C29H35N3O, with a molecular weight of approximately 441.61 g/mol. Chemically, it exhibits a light yellow crystalline powder appearance. The compound is soluble in common organic solvents such as toluene, making it adaptable for incorporation into various formulations. Its performance is characterized by broad-spectrum UV absorption, providing efficient protection for light-sensitive materials.

The primary applications for UV Absorber 928 include its use in high-performance coatings, where it shields substrates from UV-induced damage, preserving color and preventing embrittlement. It is particularly suitable for demanding applications like automotive coatings, powder coatings, and coil coatings due to its high thermal and environmental stability. Furthermore, it finds utility in plastics and adhesives, enhancing their durability when exposed to sunlight. This makes it a valuable purchase for industries requiring long-lasting material performance.

For businesses looking to buy UV Absorber 928, sourcing from a reliable manufacturer and supplier is key. Our operations in China are geared towards delivering consistent quality and competitive pricing. We ensure that our UV Absorber 928 meets stringent specifications, providing formulators with the confidence they need in their raw materials.
