UV 327

Description:

UV 327, also known by its chemical name 2-(2H-benzotriazol-2-yl)-4-(tert-butyl)-6-(sec-butyl)phenol, is a widely used ultraviolet (UV) light stabilizer. It is primarily employed in various polymer applications to protect materials from UV degradation, thereby enhancing their longevity and performance. This compound exhibits excellent thermal stability and is effective in absorbing UV radiation, preventing the breakdown of polymers and other materials exposed to sunlight. UV 327 is characterized by its high solubility in organic solvents and moderate solubility in water, making it suitable for incorporation into a variety of formulations, including plastics, coatings, and adhesives. Additionally, it is known for its low volatility, which contributes to its effectiveness in long-term applications. Safety assessments indicate that UV 327 has a low toxicity profile, but like many chemical substances, it should be handled with care to avoid environmental contamination. Overall, UV 327 plays a crucial role in enhancing the durability of products used in outdoor applications.
