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 UV protection efficacy in demanding polymer matrices over time.
Good compatibility with polyolefins, engineering plastics, and coatings without compromising mechanical properties or clarity.
Non-discoloring formulation—retains substrate color integrity and transparency even after prolonged UV exposure.
Polypropylene (PP) and polyethylene (PE) automotive interior components.
Outdoor plastic furniture and garden products exposed to direct sunlight.
Transparent polycarbonate (PC) glazing and lighting covers.
Water-based and solvent-based architectural and industrial coatings.
UV-stabilized agricultural films and greenhouse coverings.
