Highly effective UV absorption in the 290–400 nm range, particularly strong in the critical UVA region.
Excellent thermal and hydrolytic stability, ensuring long-term performance during high-temperature processing and outdoor exposure.
Low volatility and minimal migration, maintaining protection integrity in polymeric matrices over extended service life.
Compatible with a broad range of polymers including polyolefins, engineering plastics, and coatings.
Non-discoloring formulation—preserves original color and clarity without yellowing under UV stress.
Automotive interior trim and exterior components (dashboards, bumpers, seals).
Outdoor agricultural films and greenhouse covers requiring prolonged UV resistance.
Coatings for metal and plastic substrates in architectural and industrial applications.
Polypropylene and polyethylene fibers used in geotextiles and outdoor textiles.
Clear polycarbonate sheets and optical-grade acrylics for signage and lighting housings.
