Methylene bis(thiocyanate)

Methylene bis(thiocyanate) (CAS 6317-18-6), also known as methylene dithiocyanate or MBT, is a broad-spectrum biocide used to control microbial growth in industrial water systems and process fluids. Also marketed as Proxel MB.

Where is Methylene bis(thiocyanate) used?

• Water treatment and cooling towers: controls slime-forming bacteria and algae that reduce heat exchange efficiency and damage infrastructure
• Pulp and paper: suppresses microbial contamination in process water and white water circuits
• Oil and gas: inhibits sulfate-reducing bacteria responsible for microbiologically influenced corrosion in pipelines and storage tanks
• Personal care: preservative active in rinse-off and industrial cosmetic formulations
• It prevents bacterial and algal fouling in recirculating systems and industrial processes.

Good to know: Unchecked microbial growth in pulp and paper environments causes sheet defects and equipment fouling. Buyers should confirm active content and formulation compatibility when evaluating supply options.
