MPI Chemie UV-81 (531) is an ultraviolet light absorber (UVA) of the benzophenone class, imparting good light stability when used in combination with a hindered amine light stabilizer (HALS). It shows good compatibility with polyolefins and plasticized PVC. UV-81 significantly improves the resistance of clear coatings to failures upon exposure to sunlight such as discoloration, cracking, loss of gloss and loss of adhesion.
