What are the most common applications of MBT?
Mercaptobenzothiazole (MBT) is most widely utilized as a vulcanization accelerator in the rubber industry, but is also commonly used as a corrosion inhibitor to protect copper and copper alloys.
What are key characteristics of MBT?
MBT is an organic sulfur containing compound most commonly supplied as a yellow powder with a strong sulfur odor. As a corrosion inhibitor, MBT is a rapid passivator with high thermal stability but is susceptible to degradation by oxidizers.
How is MBT used in corrosion inhibition applications?
MBT is used as a copper and brass corrosion inhibitor most commonly as a sodium salt, in heat transfer fluids, automotive coolants, closed loop water treatment, cutting oils, and hydraulic fluids.
Are there any safety concerns with the use of MBT?
MBT is harmful if it is inhaled and may cause an allergic reaction if in contact with skin, so appropriate handling measures and PPE must be followed. Prior to using this material, review the SDS and follow all safety instructions.
