Highly effective UV absorption in the 290–400 nm range, especially strong in the critical UVA-II and UVB regions.
Excellent thermal and hydrolytic stability, maintaining performance during high-temperature processing (e.g., extrusion, injection molding).
Low volatility and minimal migration, ensuring long-term photostabilization in polymeric matrices.
Compatible with a broad spectrum of polymers including polyolefins, ABS, polycarbonate, and engineering thermoplastics.
Non-discoloring and chemically inert under normal use conditions—preserves substrate clarity and color fidelity.
Automotive interior plastics (dashboards, trim, instrument panels).
Outdoor polymer profiles and building materials (window frames, cladding, roofing membranes).
Packaging films for UV-sensitive contents (pharmaceuticals, agrochemicals, food).
Coatings and clear topcoats for wood, metal, and plastic substrates.
Optical-grade transparent plastics requiring long-term light stability (e.g., lenses, lighting housings).
