Properties:
2-Mercaptobenzothiazole Slightly foul odor and bitter taste, nonpoisonous. Specific gravity: 1.46-1.52.Soluble in ethyl acetone, acetone, dilute solution of sodium hydroxide and sodium carbonate, ethyl alcohol. Not easily soluble in benzene. Insoluble in water and gasoline.
Application:
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. Imparts excellent aging properties, when 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. Mainly used in the manufacture of tires, tubes, footwear, rubber belts and hoses etc. Also Used as an intermediate for cephalosporins and other drugs
Packing: In 25kgs or 500kgs net bag.
Storage: Keep container tightly closed in a cool, well-ventilated place.
