Highly effective UV absorption in the 290–400 nm range, providing broad-spectrum protection against photodegradation.
Excellent thermal and hydrolytic stability, ensuring consistent performance during high-temperature processing and long-term service life.
Low volatility and minimal migration, maintaining protective efficacy in demanding polymer matrices over time.
Good compatibility with a wide range of thermoplastics, thermosets, and coatings including polyolefins, PVC, and acrylics.
Non-discoloring and chemically inert under normal use conditions, preserving substrate clarity and color fidelity.
Automotive interior plastics (dashboards, trim components, and instrument panels).
Outdoor construction materials (PVC window profiles, roofing membranes, and cladding).
Coatings for architectural and industrial applications (acrylic-based topcoats and clear finishes).
Transparent polycarbonate and PMMA glazing used in signage and lighting fixtures.
Flexible packaging films requiring UV stability without affecting optical properties.
