Accelerator DCBS (N,N-Dicyclohexyl-2-Benzothiazolesulfenamide)
N,N-Dicyclohexyl-2-benzothiazolesulfenamide (DCBS) is a delayed-action sulfenamide accelerator offering the longest scorch time among commercial benzothiazole sulfenamides. It is the preferred accelerator for thick-section tire components and belt compounds containing insoluble sulfur, where extended processing safety is critical. DCBS delivers a high crosslink density and excellent reversion resistance upon vulcanization.
