Beschreibung
Zusammenfassung:Stabilizer compositions having a stabilizing amount of at least one co-active agent; and a stabilizing amount of any one or more ultraviolet light absorber chosen from an ortho-hydroxyphenyl triazine, an ortho-hydroxy benzophenone, or an ortho-hydroxyphenyl benzotriazole, optionally in combination with a stabilizing amount of a hindered amine light stabilizer, are provided herein, along with masterbatch concentrates containing same, and processes for using same for stabilizing organic materials to protect against light and thermal degradation due to exposure to UV irradiation.
