The chief thiazole accelerators are 2-mercaptobenzothiazole (MBT), benzoth- iazole disulfide (MBTS), and the zinc salt of 2-mercaptobenzothiazole. The zinc salt is rarely used in dry compounding but is used more in latex foams and dipped goods. Both MBT and MBTS can cause scorching problems when used alone in furnace black natural rubber stocks.
