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. In a plastic bag or kraft paper bag, 25 kg/bag or customers’ requirement. It is also recommended to use up the entire package once it has been opened, as prolonged storage can lower its effectiveness.

Synonyms:

MBT;2-MBT;2-Mercaptobenzothiazole;2-Benzothiazolethione

MBT — Frequently Asked Questions (FAQ)

What is 2-Mercaptobenzothiazole (MBT) used for?

MBT is a copper and non-ferrous-metal corrosion inhibitor for circulating cooling water, antifreeze and metalworking fluids, forming a protective film on copper surfaces.

What is the recommended dosage of MBT?

2-Mercaptobenzothiazole (MBT) is typically dosed at 1–10 ppm. The exact dose depends on water quality, temperature and the overall treatment program — VCYCLETECH provides a tailored dosing recommendation.

What should I include in a 2-Mercaptobenzothiazole (MBT) enquiry?

For metallurgy-specific corrosion-control selection, include system type and metallurgy; water chemistry and oxygen-entry pathway; corrosion, metal-release or deposit trends; existing treatment and monitoring method. State the proposed grade or specification, quantity, packaging and destination so the product and commercial requirements can be compared.
