What is N,N-dicyclohexyl-2-benzothiazolesulfenamide?
N,N-Dicyclohexyl-2-benzothiazolesulfenamide (CAS 4979-32-2), commonly known as DCBS, is a delayed-action sulfenamide accelerator used in rubber vulcanization.
Where is N,N-dicyclohexyl-2-benzothiazolesulfenamide used?
- Tire manufacturing: accelerator enabling safe processing of thick-section components such as sidewalls, treads, and bead fillers without premature cure
- Industrial rubber goods such as conveyor belts, hoses, and seals: supports crosslink density across heavy-gauge profiles
- Injection-molded and transfer-molded rubber parts: delayed onset suits extended flow time before cure initiates
- Formulators combine it with secondary accelerators such as DPG or TBBS to fine-tune cure speed and modulus development.
Commercial specifications
- Packaging from 25 kg bags to bulk quantities
- Active content confirmed by melting point and assay testing per supplier certificates of analysis
