Used as a high-performance UV stabilizer in polymer systems, particularly in polycarbonate and acrylic materials. Offers excellent protection against photodegradation, maintaining material clarity and mechanical strength under prolonged UV exposure. Commonly incorporated into coatings, films, and optical-grade plastics where long-term weatherability is critical. Shows good thermal stability and compatibility with aromatic polymers, making it suitable for high-processing-temperature applications. Also utilized in specialty adhesives and electronic encapsulants requiring UV resistance.
