UV Absorber 384 (Tinuvin 384), a benzotriazole-based compound (C₂₂H₂₉N₃O), protects materials from UV degradation by absorbing 280–400 nm light. Used in automotive coatings, packaging films, polyolefins (PP/PE), and textiles, it prevents fading, cracking, and polymer breakdown. Key benefits include high thermal stability, low volatility, and compatibility with plastics/coatings. It meets REACH/FDA standards for indirect food contact and synergizes with antioxidants/HALS for enhanced durability. Ideal for applications requiring long-term UV resistance, such as outdoor products and industrial materials, it ensures prolonged structural integrity and aesthetic quality under sunlight exposure.
UV Absorber 384 (commonly known as Tinuvin 384 or 2-(2H-Benzotriazol-2-yl)-4,6-di-tert-pentylphenol) is a benzotriazole-based organic compound used to protect materials from UV radiation degradation. Key features:
Function: Absorbs UV light (280–400 nm), preventing polymer breakdown, color fading, and loss of mechanical properties in plastics, coatings, and adhesives.
Applications: Automotive coatings, packaging films, polyolefins (e.g., PP, PE), and outdoor textiles.
Benefits: High thermal stability, low volatility, and compatibility with various polymers.
Safety: Approved under regulations like REACH and FDA for indirect food contact.
Synergy: Often blended with antioxidants or hindered amine light stabilizers (HALS) for enhanced durability.
Widely used in industries requiring long-term UV resistance.
