Highly effective UV absorption in the critical 300–400 nm range, providing superior photostabilization for organic substrates.
Excellent thermal and hydrolytic stability, ensuring long-term performance during high-temperature processing and outdoor exposure.
Low volatility and minimal migration, maintaining protective efficacy in thin films and demanding polymer applications.
Good compatibility with a broad range of polymers including polyolefins, styrenics, engineering plastics, and coatings.
Non-discoloring and chemically inert under normal use conditions, preserving optical clarity and color fidelity.
Automotive interior and exterior plastic components (e.g., dashboards, bumpers, trim).
Outdoor architectural coatings and industrial maintenance paints.
Polyolefin-based agricultural films and geomembranes.
Transparent polycarbonate and acrylic glazing for façades and lighting fixtures.
UV-stabilized packaging films for pharmaceuticals and premium consumer goods.
