Durazone 37 2,4,6-Tris-(N-1,4-dimethylpentyl-p-phenylenediamino)-1,3,5-triazine Crompton-Uniroyal Chemical Antioxidants >> Amine Rubber - Elastomer (Chloroprene, Butyl …) DURAZONE ® 37 Antioxidant/Antiozonant 2,4,6-Tris-(N-1,4-dimethylpentyl-p-phenylenediamino)-1,3,5-triazine Offers excellent static and dynamic ozone protection and excellent antioxidant protection. Durazone 37 is a nonstaining antiozonant offering superior static ozone protection, excellent dynamic protection and excellent antioxidant protection. Durazone 37 will not migrate stain from a black compound to a white compound adjacent to it. Therefore, migration staining of the white compound will not occur. As a compounding ingredient, Durazone 37 is added into rubber above its melting point of 75 ºC (167 ºF) in quantities of 2 to 4 parts per 100 parts RHC. Durazone® 37 is unique in providing excellent antiozonant protection without staining. Superior static protection and a synergy with Flexzone® 7L are also unprecedented. 2,4,6-Tris-(N-1,4-dimethylpentyl-p-phenylenediamino)-1,3,5-triazine. Used as a nonstaining antiozonant.
