Highly effective UV absorption in the 290–400 nm range, protecting polymers from photodegradation.
Excellent thermal and hydrolytic stability, ensuring consistent performance during high-temperature processing.
Low volatility and good compatibility with a broad range of thermoplastics and thermosets.
Non-discoloring and chemically inert under normal use conditions, preserving substrate clarity and color fidelity.
Regulatory compliant for selected applications, including FDA-listed indirect food contact (21 CFR §178.3740).
Polypropylene (PP) fibers and nonwovens for outdoor geotextiles and agricultural fabrics.
Automotive interior plastics, including instrument panels and trim components.
Coatings for architectural and industrial metal substrates.
Polycarbonate (PC) and acrylic (PMMA) glazing and lighting lenses.
Adhesives and sealants exposed to prolonged solar irradiation.
