Buy UV ABSORBER UV384-2 CAS 127519-17-9 China supplier
UV Absorber UV384-2 (chemical name: typically a substituted benzotriazole or triazine derivative, depending on the manufacturer; e.g., 2-(2H-benzotriazol-2-yl)-6-dodecyl-4-methylphenol or similar structures) is a high-performance organic UV stabilizer designed to protect materials from ultraviolet (UV) radiation-induced degradation. It offers broad-spectrum absorption in the UV-A (320–400 nm) and UV-B (280–320 nm) ranges, making it critical for enhancing the durability of polymers, coatings, and related products. Below are its key applications in English contexts:
Structural Adhesives
Added to acrylic, polyurethane, and epoxy adhesives used in outdoor bonding applications (e.g., solar panel assembly, automotive glazing, and aerospace composites) to prevent UV-induced degradation of adhesive properties.
Sealants
Stabilizes silicone, acrylic, and polyurethane sealants in building and construction (e.g., window frames, roofing joints) to maintain elasticity and weather resistance.
Exterior Components
Protects automotive plastics (e.g., bumpers, trim panels, headlamp lenses), rubber parts (e.g., tires, weather stripping), and coatings (e.g., clear coats) from UV damage, ensuring color stability and surface integrity over the vehicle’s lifetime.
Aerospace Materials
Used in aircraft coatings, cabin materials, and exterior composites to resist UV radiation at high altitudes, where exposure is more intense.
Packaging Films
Stabilizes polyethylene (PE) and polypropylene (PP) films used for food packaging, agricultural films (e.g., greenhouses, mulch films), and stretch wraps, preventing premature degradation from sunlight.
