Description

Uv Absorber Uv-9 is a highly effective benzophenone-type ultraviolet light stabilizer, widely recognized for its ability to protect materials from UV-A radiation. Its primary value lies in preventing photodegradation, thereby extending the service life and maintaining the aesthetic and mechanical properties of polymers and coatings. This product is essential for formulators and manufacturers in the plastics, coatings, adhesives, and personal care industries seeking reliable UV protection for their sensitive formulations.

Application

  • As a light stabilizer in polyolefins (PP, PE), PVC, and other thermoplastic resins.
  • Protective additive for industrial and automotive coatings, varnishes, and lacquers.
  • UV filter in personal care products such as sunscreens and cosmetic formulations.
  • Stabilizing agent for adhesives, sealants, and printing inks.
  • Enhancing the weatherability of synthetic fibers and textiles.
  • Protection of packaging materials from UV-induced discoloration and embrittlement.
