Overview

MBM (Methylene Bisthiocyanate) is a highly active, sulfur-containing biocide designed for broad-spectrum microbial control in challenging industrial environments. It exhibits strong efficacy against bacteria, fungi, and algae, including resistant strains in high organic load systems. MBM is a non-oxidizing biocide that works by disrupting microbial enzymatic activity, ensuring fast and irreversible cell death. Its rapid degradation and minimal residue generation reduce the risk of long-term environmental buildup. MBM is especially valued in oil & gas, pulp & paper, and recirculating water systems where quick kill and low persistence are required. MBM is prized for its rapid action, low required dosage, and high efficacy against slime-forming organisms. Its stability in acidic environments and non-foaming properties make it suitable for closed-loop systems. Due to its powerful performance and biodegradability, MBM is commonly used where fast microbial knockdown is essential.

Benefits

• Rapid Microbial Kill – Fast-acting control of bacteria, fungi, and algae

• Effective in Acidic pH – Performs well in low pH environments (3–6)

• Low Dosage Efficiency – Delivers results with minimal chemical usage

• Non-Foaming Action – Ideal for closed-loop and high-speed systems

• Degrades Quickly – Breaks down without forming persistent residues

• Non-Oxidizing Type – Suitable where oxidative corrosion is a concern

Applications

• Oilfield Injection and Produced Water – Controls microbial-induced corrosion and SRB

• Cooling Water & Process Water Systems – Eliminates microbial fouling and biofilm

• Pulp & Paper Mills – Inhibits microbial growth in white water and process lines

• Industrial Wastewater Treatment – Maintains effluent microbial balance

• Adhesives & Polymer Emulsions – Preserves products during storage and usage

• Mining & Metallurgical Operations – Controls biological slime in water circuits
