  • What does ZMBT stand for?
  • Zinc 2-Mercaptobenzothiazole (ZMBT) is widely used in the rubber processing industry and is an essential high-efficiency rubber vulcanization accelerator for natural and synthetic rubber. Molecular Formula: C14H8N2S4Zn CAS No. 155-04-4 EC No. 205-840-3
  • What is a ZMBT accelerator?
  • WESTCO™ ZMBT accelerator is a primary accelerator for NR, SR and their latices; used as a secondary accelerator in sulfur cured latex. *Moisture,% max. *Residue on 100 mesh sieve,% max. *Residue on 230 mesh sieve,% max. Technical Product Sheets and SDS sheets are available for each of the chemicals listed. To access please click on the links above.
  • Does ZMBT destabilize latex?
  • ZMBT does not destabilize latex formulations. In dry rubber applications, the performance of ZMBT is almost similar to MBT, with slight scorch improvement. Zinc 2-Mercaptobenzothiazole is commonly used as an accelerator in the rubber vulcanization process, improving tensile strength and aging resistance.
  • What is ZMBT used for?
  • ZMBT’s main application is latex, where it is used as a primary accelerator in combination with ZDMC or ZDEC. Latex films cured with ZMBT have a markedly higher modulus. Furthermore, a better compression set resistance in latex foam can be achieved without increasing the cure time. ZMBT does not destabilize latex formulations.
  • How many PHR of ZMBT should a secondary accelerator use?
  • Using 2-4 phr of ZMBT with 0.5 – 0.05 phr thiuram and low sulfur exhibits outstanding resistance to heat. Typical use in mechanical goods would be 0.8 – 1.2 phr. ZMBT, 0.01 – 0.5 phr of a secondary accelerator with ordinary sulfur.
