Properties and Usage:

2-Mercaptobenzothiazole (MBT) has a slightly foul odor and bitter taste but is non-poisonous. It is easily soluble in ethyl acetone, acetone, a dilute solution of sodium hydroxide and sodium carbonate, and also soluble in ethyl alcohol. MBT is not readily soluble in benzene and is insoluble in water and gasoline. This hemi-ultra accelerant is widely used for vulcanizing natural and synthetic rubbers. Its main applications are for producing rubber tires, belts, shoes, and other technical rubber goods.

Package and Storage:

2-Mercaptobenzothiazole (MBT) should be packed in tightly sealed bags or containers. The product must be kept in dry and cool places, away from direct sunlight and sources of heat. The ambient temperature should not exceed 40°C (104°F). Storage time shall be limited to two years, as the product may degrade over time.
