Zinc 2-mercaptobenzothiazole

Zinc 2-mercaptobenzothiazole (CAS 155-04-4), commercially known as ZMBT, Zetax, Zenite, Oxaf, and Bantex, is an organometallic compound derived from 2-mercaptobenzothiazole and zinc. It carries no assigned E-code and is classified under HS code 2934.20.8000 for customs purposes.

In rubber vulcanisation, ZMBT functions as a delayed-action accelerator, coordinating with sulfur crosslinks to improve cure efficiency and reduce scorching risk in both natural and synthetic rubber compounds. It also serves as an antioxidant stabiliser in polymer formulations, where its zinc-sulfur coordination chemistry interrupts oxidative chain reactions and extends service life of finished articles.

ZMBT is supplied as a solid powder and is subject to REACH registration requirements within the European Economic Area. Procurement teams should confirm supplier compliance documentation, including Safety Data Sheets aligned with EU GHS standards. Standard packaging formats vary by supplier; bulk and intermediate bag quantities are typically available for industrial volumes.
