Zinc di-n-butyldithiocarbamate

Zinc di-n-butyldithiocarbamate (CAS 136-23-2), commonly abbreviated ZBC or ZDBD and sold under trade names including Butazate and Accelbz, is an organozinc dithiocarbamate compound with no assigned E-code. It belongs to the dithiocarbamate accelerator family and is classified under HS code 2931.90.9051.

In rubber processing, ZBC functions as an ultra-fast primary or secondary vulcanization accelerator, promoting sulfur crosslink formation at lower temperatures and shorter cure times. It also serves as an antimicrobial agent in select preservation applications and has documented use as a flavorant and fragrance component in food and personal care formulations.

This material is supplied as a solid powder suitable for direct compounding or dispersion. It is handled under REACH registration requirements applicable to EU markets. Procurement teams should confirm grade specifications against application requirements, as food-contact and industrial rubber grades carry distinct compliance documentation.
