MERCAPTOBENZOTHIAZOLE (MBT) Chemical compatibility with O-rings, rubbers, & plastics

Mercaptobenzothiazole (MBT) is a white to pale yellow crystalline solid with the chemical formula C₇H₅NS₂, used in various industrial applications. It is primarily employed as a vulcanization accelerator in the production of rubber products, enhancing the cross-linking process to improve durability and elasticity. MBT is also used as a corrosion inhibitor in lubricants and metalworking fluids. Despite its utility, MBT can cause skin, eye, and respiratory irritation if not handled properly. Proper handling, storage, and safety measures, including the use of personal protective equipment, are essential to ensure safe usage and prevent exposure.
