Highly effective benzotriazole-type UV absorber with strong absorption in the 300–400 nm range.
Excellent thermal and hydrolytic stability, suitable for high-temperature polymer processing.
Low volatility and good compatibility with a broad range of polymers including polyolefins, PVC, and engineering plastics.
Provides long-term protection against photooxidative degradation without significant color formation.
Compatible with other additives such as hindered amine light stabilizers (HALS) for synergistic stabilization effects.
Automotive interior components (e.g., dashboards, trim, seat fabrics).
Outdoor building materials (e.g., PVC window profiles, roofing membranes, cladding).
Agricultural films and greenhouse covers requiring extended UV durability.
Packaging films for UV-sensitive consumer goods and pharmaceuticals.
Coatings and inks for exterior signage and industrial finishes.
