Highly effective UV absorber based on benzotriazole chemistry, offering broad-spectrum protection against UVA and UVB radiation.
Excellent thermal and light stability, maintaining performance during high-temperature processing such as extrusion and injection molding.
Low volatility and minimal migration, ensuring long-term UV resistance in polymer matrices without surface blooming.
Good compatibility with a wide range of thermoplastics, thermosets, and coatings including polyolefins, PVC, ABS, and polyesters.
Non-discoloring and chemically inert under normal use conditions, preserving substrate clarity and color fidelity.
Automotive interior plastics (dashboards, trim, upholstery) requiring long-term weatherability.
Outdoor construction materials including PVC window profiles, roofing membranes, and cladding panels.
Engineering plastics for consumer electronics housings exposed to indoor and ambient sunlight.
Coatings and inks for signage, packaging, and industrial labeling demanding UV-induced fade resistance.
Transparent polycarbonate and acrylic glazing used in architectural and transportation applications.
