This rubber vulcanization accelerator belongs to the mercaptobenzothiazole-sulfenamide group. It is used as a chemical in the rubber industry, especially in the production of synthetic rubber articles. It is contained in “mercapto mix.” As a corrosion inhibitor, it can be found in cutting fluids or in releasing fluids in the pottery industry. It induces mainly delayed-type hypersensitivity, but a case of immediate-type hypersensitivity was reported in a dental assistant.
LogP 3.4 at 25℃ and pH7
Uses
Delayed-action vulcanization accelerator.
Dissociation constant -6.82-2.65 at 25℃
