Cure-Rite® BBTS

Cure-Rite® BBTS is a general purpose and our first-choice sulfenamide accelerator.   Consumers will benefit from fast, ZERO nitrosamine, delayed-action vulcanization in a broad variety of diene-containing elastomers, including but not limited to NR, SBR, NBR and BR .  Compounders appreciate that Cure-Rite® BBTS is added at the end of the mixing cycle and easily disperses in all rubber.  Compared to CBS, Cure-Rite® BBTS offers better scorch protection at typical loadings (0.5-4.0 phr).
