Octolite 640 Synergistic blend of polymeric hindered phenol and thioester Tiarco Chemical Antioxidants >> Phenolic Antioxidants >> Thioester Chloroprene Rubber (CR) Rubber - Elastomer (Chloroprene, Butyl …) ADHESIVE Synergistic blend of polymeric hindered phenol and thioester (Goodyear's Wingstay SN-1). Octolite 640 is non-staining, non-discoloring in performance and provides highly efficient stabilization and antioxidant protection in SBR and Natural , and Neoprene latex polymers. The recommended use level is 0.25 to 1.0 parts per hundred polymer for most applications. Octolite 640 is particularly useful in some latex polymer compounds by providing superior protection against high-temperature degradation. Synergistic blend of polymeric hindered phenol and thioester. Used as non-staining, non-discoloring antioxidant for adhesives and latex systems. Provides very good stabilization, antioxidant protection and protection against high-temperature degradation. Use level: 0.25 to 1.0 parts per hundred polymer.
