What is Mercaptobenzothiazole Used for
For the Rubber Industry: MBT serves as a highly effective vulcanization accelerator in the manufacturing of tires, inner tubes, shoes, and various industrial rubber goods.
In Metal Analysis: 2-Mercaptobenzothiazole is used as a sensitive reagent for the detection and analysis of metals such as gold, bismuth, lead, and copper.
As a Corrosion Inhibitor: 2-Mercaptobenzothiazole (MBT) acts as an effective corrosion inhibitor specifically for copper and copper alloys in systems like cooling circuits.
In Chemical Synthesis: 2-Mercaptobenzothiazole functions as a key intermediate in the production of herbicides (e.g., mefenacet) and certain pharmaceuticals (e.g., cephalosporin antibiotics).
For Other Applications: MBT can also be used as a brightener in copper sulfate electroplating and as a solvent stabilizer in polyurethanes, resins, and paints.
FAQ of Mercaptobenzothiazole
Oiled MBT contains 1-2% mineral oil, which significantly reduces dust fly-loss in the workshop. This not only improves occupational health for workers but also prevents material loss and enhances the dispersion of the accelerator during the milling process.
MBT reacts with copper ions to form a thin, insoluble protective film (chelate) on the metal surface. This molecular barrier prevents oxygen and corrosive ions from attacking the copper, even at very low concentrations.
MBT (2-Mercaptobenzothiazole) is a multifunctional organosulfur compound. In the rubber industry, it is used as a “primary accelerator,” significantly accelerating vulcanization and enhancing the aging resistance of rubber, and is widely used in tires, belts, and rubber shoes. Furthermore, in the water treatment field, it is an excellent copper corrosion inhibitor, preventing the corrosion of copper and its alloys by forming a passivation film on the metal surface.
Our MBT is available in standard 25kg bags and in bulk 15 metric ton containers to accommodate different scale requirements.
Store MBT in a cool, dry, and well-ventilated place, in its original tightly sealed packaging away from direct sunlight, heat sources, and oxidizing agents.
