  • Applications

    Benzophenone-5, CAS 6628-37-1, is used as a UV absorber and stabilizer to improve the photostability of polymers and plastics under UV exposure. Typical applications include protecting plastics and polymers in formulations, serving as a UV absorber in coatings and inks to enhance weathering resistance, stabilizing adhesives to improve photostability, and acting as a UV filter or photostability additive in cosmetics and personal care products; it is also considered for electronics to shield plastic components from UV exposure. Subject to local regulations and formulation limits.
