WESTCO™ ZDBC (BZ) Accelerator (ZDBC) Zinc Dibutyldithiocarbamate CAS# 136-23-2 WESTCO™ BZ is a rubber accelerator for natural and synthetic rubber and latex. Provides fast cures at low temperatures; slower cure rates than with EZ (ZDEC) or MZ (ZDMC).
Used in dry rubber, it gives good scorch safety. ZDMC can be used as primary or secondary accelerator for NR, IR, SBR, NBR, IIR and EPDM. Faster cure than TMTD, but better scorch safety. Seldom used alone, usually used as secondary accelerator. Used also for low temperature and fast cure. Generally requires a thiozole for safe processing.
