Applications:
Uses: Delayed-action slow curing sulfenamide accelerator. DCBS has the best scorch
resistance of all sulfonamide accelerators. DCBS provides lower modulus than CBS, TBBS,
MBS, MOR, thus will require higher use levels for equivalent physicals. DCBS is more often
used in steel skim compounds for improved adhesion. Stocks containing DCBS can be stored for long time without deterioration in scorch safety or vulcanisate properties. DCBS is highly suitable and widely used in retread, large tires, shock absorbers and conveyor belts.

Polymers: Natural rubber, synthetic Polyisoprene, Polybutadiene, SBR and NBR.

Synergism: DCBS cure performance can be boosted with thiuram or guanidine accelerators.

Cure Effect: Promotes a slow cure rate with good scorch safety. Increasing accelerator/sulfur ratio enhances the cure efficacy.
