CMIT/MIT 14% is a high-performance broad spectrum antimicrobial agent based on isothiazolinone chemistry. It is an aqueous solution containing a 3:1 mixture of 5-Chloro-2-methyl-4-isothiazolin-3-one (CMIT, CAS 26172-55-4) and 2-Methyl-4-isothiazolin-3-one (MIT, CAS 2682-20-4), with a total active ingredient concentration of 14.0-14.5%. The product also contains magnesium chloride (4.0-7.0%), magnesium nitrate (18.0-24.0%) and water as stabilizers and solvents.

This industrial microbicide is highly effective at very low concentrations in controlling microorganisms that cause microbial induced spoilage. It provides long-lasting protection against a wide range of bacteria, yeast and fungi over a broad pH range. CMIT/MIT 14% is EPA registered and widely used as a preservative in various industrial applications including water treatment, synthetic polymer lattices, metal working fluids, papermill slimicides, adhesives and water-based paints.

Our CMIT/MIT 14% is produced with advanced manufacturing technology, with full batch traceability and complete supporting quality documents. We can provide customized specifications to meet specific customer requirements and ensure long-term stable bulk supply for global industrial manufacturers.

1. Water Treatment Industry (Core Application): Used as biocide for cooling water systems, reverse osmosis systems, industrial process water and wastewater treatment. Controls bacterial growth and prevents biofilm formation.
2. Synthetic Polymer Lattices: Applied as preservative for styrene/butadiene, ethylene/vinyl acetate, polyvinylacetate and other polymer emulsions. Prevents microbial spoilage during storage and use.
3. Metal Working Fluids Industry: Used as preservative for soluble oils, semi-synthetic and synthetic metal working fluids. Extends fluid service life and prevents bacterial degradation.
4. Papermill Industry: Applied as slimicide to control microbial growth in paper mill process water. Prevents slime formation and improves paper quality.
5. Paints & Coatings Industry: Used as preservative for water-based paints, latex coatings and architectural coatings. Prevents in-can spoilage and post-application fungal growth.
6. Adhesives Industry: Applied as preservative for water-based adhesives, glues and sealants. Prevents microbial degradation and maintains adhesive performance.
7. Raw Materials Preservation: Used to preserve surfactants, emulsions, pigments and other industrial raw materials during storage and transportation.

A1: The recommended dosage varies by application:

• Water treatment: 10-50 ppm active ingredient
• Metal working fluids: 5-30 ppm active ingredient
• Paints and adhesives: 2-15 ppm active ingredient
• Polymer lattices: 5-20 ppm active ingredient
• Papermill slimicides: 10-40 ppm active ingredient

The actual required concentration depends on the level of microbial contamination and the necessary protection period.

A2: CMIT/MIT 14% is effective over a broad pH range of 2.0-9.0. Optimal performance is achieved between pH 4.0 and 8.0. It is not recommended for use in strongly alkaline systems (pH > 9.5) as it will decompose rapidly.

A3: CMIT/MIT 14% is compatible with most surfactants, emulsifiers, dispersants and other common industrial chemicals. However, it is incompatible with strong reducing agents, strong oxidizing agents, amines and mercaptans. It is recommended to conduct compatibility tests before use in new formulations.

A4: CMIT/MIT 14% is corrosive and may cause skin and eye burns. Required PPE includes:

• Chemical-resistant gloves (nitrile or butyl rubber)
• Safety goggles with face shield
• Chemical-resistant apron and protective clothing
• Respiratory protection if working in poorly ventilated areas

A5: In case of spill:

• Wear appropriate PPE
• Contain the spill to prevent spread to drains and waterways
• Absorb with inert material such as sand or vermiculite
• Collect in suitable closed containers for disposal
• Wash the area thoroughly with water
• Do not allow product to enter the environment as it is very toxic to aquatic life

A6: CMIT/MIT 14% has a shelf life of 12 months when stored in tightly closed original containers at temperatures between 1℃ and 55℃. It should be stored in a cool, dry, well-ventilated area away from direct sunlight, heat sources and incompatible materials. Do not store in steel containers as it is corrosive to carbon steel.
