rate faster. In terms of processing safety, Benzothiazyl 1,2-dicyclohexyl sulfenamide is the highest, with N-cyclohexyl-2-benzothiazole sulfenamide the lowest. The trend is to use the modifications of the original sulfenamide accelerators that give greater processing safety. A popular accelerator is N-tert-butyl-2-benzothiazolesulfenamide (BBTS).
