2-mercaptobenzothiazole (MBT) is an important variety of thiazole rubber vulcanization accelerators. At the same time, it is also an important auxiliary agent for oxidation and corrosion resistance.

2-mbt
2-MBT is a pale yellow powder or granule. It has an unpleasant smell. The melting point is above 173.0°C. The relative density is 1.41 to 1.48. 2-mercaptobenzothiazole is poorly soluble in water and n-hexane. It is easily soluble in acetone. And soluble in ethanol. Slightly soluble in benzene.

2-mercaptobenzothiazole (MBT) is acidic. Vulcanization promotes strong. The vulcanization curve is relatively flat. Less polluting.

2-Mercaptobenzothiazole is a general-purpose vulcanization accelerator and is widely used in 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. 2-Mercaptobenzothiazole is often used in combination with other accelerator systems.

For example, in combination with dithiothiuram and bismuth dithiocarbamate, it can be used as a vulcanization accelerator for butyl rubber.

It can be used together with tribasic cis-butyl succinate for use in light-colored, water-resistant chlorosulfonated polyethylene compounds.

It is often used in combination with dithiocarbamate in latex. When used in combination with diethyldithiocarbamate diethylamine, it can be vulcanized at room temperature.

2-mercaptobenzothiazole (MBT) is easily dispersed and not contaminated in rubber. However, due to its bitter taste, it is not suitable for rubber products that come into contact with food.

The dye S-GL (C.I. Disperse Red 121) was prepared by refluxing 2-mercaptobenzothiazole with 1-amino-4-nitroindole and potassium carbonate in dimethylformamide for 3 h.

This dye is used for the dyeing of polyester and its blended fabrics.

When 2 mercaptobenzothiazole (MBT) is used as an electroplating additive, it is also called an acid copper plating brightener. It is used as a paving brightener when bright copper plating with copper sulfate as the main salt.

Mainly used as a brightener for bright copper sulfate. It has a good leveling effect. The general dosage is 0.05-0.10 g/L. It can also be used as a brightener for cyanide silver plating. After adding 0.5 g/L, the cathode polarization was increased. Thereby, the silver ion crystals are aligned to form a bright silver plating layer.

In addition, 2-mercaptobenzothiazole is also used in the preparation of 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, 2-mercaptobenzothiazole is also a reagent for chemical analysis. The product is low in toxicity and has a stimulating effect on skin and mucous membranes.

This product is one of the effective corrosion inhibitors for copper or copper alloys. When the cooling system contains copper equipment and the raw water contains a certain amount of copper ions, 2-mercaptobenzothiazole can be added. It can prevent corrosion of copper.

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

There are many polyaspartic acid manufacturers and suppliers on Google. Some of them are trading companies, and some are real manufacturers. They are also under the banner of manufacturers and have also done “factory field certification”. This is also the case in many B2B yellow pages. Therefore, the business license says that the manufacturer may […]

The basic types of papermaking fungicides are mainly divided into two categories: inorganic fungicides and organic fungicides. According to different action principles, inorganic fungicides can be divided into oxidized type and reduced type. The reducing bactericide has a bactericidal effect due to its reducibility. Such as sulfurous acid and its salts. Oxidizing fungicides use their […]

Abstract: A water-soluble copolymer scale inhibitor was synthesized from acrylic acid (AA) and 2-acryloyl-2-methyl propane sulfonic acid (AMPS). The scale inhibition and dispersion properties of the copolymer were determined. The effects of monomer ratio, reaction temperature and molecular weight modifier on the scale inhibition performance of the copolymer were investigated. Keywords: sulfonic acid, copolymer, scale […]
