Mainly used in the manufacture of tires, inner tubes, tapes, rubber shoes, and other industrial rubber products. In latex, it is often combined with dithiocarbamate, and when paired with diethylamine diethyldithiocarbamate, vulcanization can take place at room temperature.
The product exhibits low toxicity but possesses an irritating effect on the skin and mucous membranes. Proper safety precautions should be observed during handling and storage.
2-Mercaptobenzothiazole is primarily used as a general-purpose vulcanization accelerator in natural and synthetic rubbers for manufacturing tires, inner tubes, tapes, and rubber shoes. It is also used as an electroplating brightener, metal corrosion inhibitor, and chemical intermediate.
No. Although 2-Mercaptobenzothiazole is easy to disperse in rubber and non-polluting, it has a bitter taste, making it unsuitable for use in rubber products that come into contact with food.
In electroplating, it is known as acid copper plating brightener M. Used at a dosage of 0.05–0.10 g/L, it acts as a brightener with good leveling effects for bright copper plating. It can also be applied in cyanide silver plating at 0.5 g/L to enhance bright silver coating layers.
It is an effective corrosion inhibitor for copper and copper alloys. It is added to cooling systems containing copper equipment where raw water contains copper ions to prevent copper corrosion.
It should be stored at temperatures below +30°C. The substance is stable under proper conditions, but it is flammable and incompatible with strong oxidizing agents.
Accelerator M serves as an intermediate for producing accelerators such as MZ, DM, NS, DIBS, CA, DZ, NOBS, and MDB, as well as the herbicide fenthiofen and dye disperse brilliant red S-GL.
