This compound is a high?efficiency UV absorber (triazine?type), mainly absorbing UV light at 280–350 nm. It is widely used in plastics, coatings, adhesives, and synthetic rubbers to prevent polymer degradation, yellowing, and brittleness caused by UV radiation. It exhibits excellent thermal stability and compatibility with various resins (PVC, PE, PP, epoxy, acrylic). In cosmetics, it serves as a safe, broad?spectrum UV filter in sunscreens, lotions, and lipsticks, protecting skin from UV?induced aging and damage. It is also used in high?grade inks and paper coatings to improve light fastness and extend service life.
