Highly effective UV absorber based on benzotriazole chemistry with strong absorption in the 290–400 nm range.
Excellent thermal and hydrolytic stability, enabling robust performance during high-temperature polymer processing.
Low volatility and minimal migration, ensuring long-term protection in demanding outdoor applications.
Good compatibility with a broad range of polymers including polyolefins, engineering plastics, and coatings.
Non-discoloring and chemically inert under normal use conditions, preserving substrate aesthetics and integrity.
Automotive exterior plastics (e.g., bumpers, grilles, trim components).
Outdoor construction materials (e.g., PVC profiles, roofing membranes, geotextiles).
Transparent polycarbonate glazing and lighting covers.
Coated wood composites and fiber-reinforced polymer (FRP) panels.
Polyolefin-based agricultural films and geomembranes.
