Properties:Light yellow powder, No osmyl and a little taste bitter. Soluble in acetone, alcohol,insoluble in benzene,gasoline and water.
Application:Developed to replace thiurams such as TMTD where the presence of nitrosamines is of concern The dibenzylnitrosamine is not carcinogenic according to published literature. A fast curing primary secondary accelerator in NR, SBR and NBR applications. Be safer to progress, providing longer scorch times than TMTD. Sometime used as retarder in the vulcanisation of PVC rubber.
