Isothiazolinones (also CMIT/MIT) is a blended biocide with methylchloroisothiazolinone and methylisothiazolinone which carry out the bactericidal effect through breaking the bond of bacteria and algae cell protein. When isothiazolinones contact with microbes, it can quickly break cell protein bond and inhibit their growth, and then lead to the apoptosis of these microbes. Isothiazolinone products can be effective in controlling both the planktonic and surface growth at very low concentrations and have been produced specifically for oilfield water treatment and paper mill applications. CMIT/MIT has strong biocidal effects on ordinary bacteria, algae and fungi which has many advantages such as no residue, good compatibleness, high stabilization, good degradation, safety and low cost in operation. Isothiazolinone products can mix with other chlorine biocides and most cation, anion, and non-ionic surfactants. It can be an excellent eco-friendly sludge remover when used at high dosage. Methylchloroisothiazolinone and methylisothiazolinone are fungicidal with properties of high efficiency, broad spectrum, non-oxidative and low toxicity. CMIT/MIT is the most suitable biocide in industrial circulating cool water systems and in wastewater treatment for oilfield, papermaking, pesticide and other industries. Bichain is one of reliable isothiazolinones manufacturers and suppliers of CMIT/MIT, methylchloroisothiazolinone and methylisothiazolinone for oilfield water treatment. We supply high quality isothiazolinone products like Kathon WT with CAS 55965-84-9.

Package and Storage
Package: 200L plastic drum, IBC (1000L) or customers’ requirement. Store in dry cool and ventilation environment.
Shelf time: 10 months
Recommended Dosage
When Grade II used as a sludge remover, the recommended dosage is 150-300mg/L. When used as a boicide, the dosage of 80-100mg/L is preferred and charges every 3-7 days. Don't use together with oxidative fungicidal such as chlorine, and don't use in cooling water system containing sulphate. When used together with BAC 80% and DDBAC, the bactericidal effect will be better. When used as a industrial fungicide, the recommended dosage is 0.05-0.4%
