Widely used as a UV absorber in polymer systems to prevent photo-degradation. Offers excellent protection in polycarbonates, polyesters, and acrylics exposed to sunlight. Commonly added to coatings and adhesives to enhance weatherability and prolong service life. Effective in clear and pigmented formulations due to its high compatibility and low color contribution. Frequently chosen for outdoor applications such as automotive parts, construction materials, and agricultural films where long-term UV stability is critical.
