This product is widely used as a general-purpose vulcanization accelerator for various rubbers. It has a vulcanization-promoting effect on natural rubber and synthetic rubber which is usually vulcanized with sulfur. However, activation of zinc oxide, fatty acid, etc. is required before use. Often used in combination with other accelerator systems, such as disulfide thiuram and bismuth dithiocarbamate as a vulcanization accelerator for butyl rubber; combined with tribasic butyl succinate, for light color Water resistant chlorosulfonated polyethylene compound. In the latex, it is often used in combination with a dithiocarbamate, and when used in combination with diethyldithiocarbamate, it can be vulcanized at room temperature. The product is easy to disperse and not pollute in rubber. However, due to its bitter taste, it is not suitable for rubber products that come into contact with food. Promoter M is an intermediate of promoters MZ, DM, NS, DIBS, CA, DZ, NOBS, MDB, etc., 2-mercaptobenzothiazole with 1-amino-4-nitroguanidine and potassium carbonate in dimethyl The dye-dispersed brilliant red S-GL (CI Disperse Red 121) was obtained by refluxing for 3 h in formamide.

This dye is used for the dyeing of polyester and its blended fabrics. 2-Mercaptobenzothiazole, also known as acid copper plating brightener M, is used as a plating brightener when it is used for bright copper plating with copper sulfate as the main salt.

In addition, the product is also used to prepare pesticide fungicides, nitrogen fertilizer synergists, cut-off oils and lubricant additives, organic anti-ashing agents in photographic chemistry, metal corrosion inhibitors and the like. In addition, it is a reagent for chemical analysis. The product is low in toxicity and has a stimulating effect on skin and mucous membranes.

Used as a sensitive reagent for the determination of gold, bismuth, cadmium, cobalt, mercury, nickel, lead, antimony and zinc and a rubber accelerator.

Mainly used in the manufacture of tires, inner tubes, tape, rubber shoes and other industrial rubber products.

This product is one of the effective corrosion inhibitors for copper or copper alloy. When the cooling system contains copper equipment and raw water contains a certain amount of copper ions, this product can be added to prevent copper corrosion.

2-Mercaptobenzothiazole is an intermediate of the herbicide mefenacet, and is also a rubber accelerator and an intermediate thereof.

Mainly used as a brightener for bright copper sulfate. Has a good leveling effect. The general dosage is 0.05~0.10 g/L. It can also be used as a brightening agent for cyanide silver plating. After adding 0.5 g/L, the cathode polarization is increased, and the silver ion crystals are aligned and arranged to obtain a bright silver plating layer.
