(1) MBT/2-Mercaptobenzothiazole is used for NR, IR, SBR, NBR, HR and EPDM. One of the mainly used acidic accelerators currently and a medium fast primary accelerator.
(2) Imparts excellent aging properties, when MBT/2-Mercaptobenzothiazole is used both alone and in combination with DM, TT and many others, mainly basic accelerators for higher activity. But care should be taken because it has a slight tendency to scorch.
(3) MBT/2-Mercaptobenzothiazole unsuitable for use in the manufacture of food contact materials.
(4) MBT/2-Mercaptobenzothiazole is mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc.
