What is CMIT-MIT?

CMIT-MIT is a water treatment agent with excellent performance and good miscibility. It can be miscible with various corrosion inhibitors such as chlorine, scale inhibitors and dispersants, most of anionic, cationic and non-ionic surfactants, and is circulated in the market The product is usually a mixture of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI), but also Metal nitrite or metal nitrate is added to improve stability and prevent decomposition. The mechanism of action of isothiazolinone is to break the bond between bacteria and algae protein to kill. After contact with microorganisms, it can quickly and irreversibly inhibit Its growth leads to the death of microbial cells, and has a strong inhibitory and killing effect on common bacteria (sulfate reducing bacteria, sludge forming bacteria), fungi (iron oxidizing bacteria, molds, yeasts), algae, etc.


1. CMIT-MIT is used to treat industrial circulating water, which has the effect of sterilization and algae killing.

2. CMIT-MIT is a general antiseptic and antiseptic, which can effectively kill algae, bacteria and fungi.

3. CMIT-MIT can be widely used in industrial cooling water, oil field tank water, paper industry, pipeline, paint, paint, rubber, cosmetics, photosensitive film and detergent industries.

4. The effective dosage of CMIT-MIT is small, non-toxic and non-polluting. It is easy to mix in various formulations. The pH range is wide. After the concentration is diluted, it is easily biodegraded into non-toxic and non-polluting substances.
