Isothiazolinone is mainly composed of 5-chloro-2-methyl-4-isothiazolin-3-one (CMI) and 2-methyl-4-isothiazolin-3-one (MI). Isothiazolinone exerts its bactericidal effect by breaking the bonds between bacterial and algal proteins. After coming into contact with microorganisms, isothiazolinone can rapidly and irreversibly inhibit their growth, leading to the death of microbial cells. Therefore, it has strong inhibitory and killing effects on common bacteria, fungi, algae, etc. It has the characteristics of high killing efficiency, good degradability, no residue production, safe operation, good compatibility, strong stability, and low usage cost. Can be miscible with chlorine and most anionic, cationic, and nonionic surfactants. At high doses, isothiazolinone has a significant effect on the stripping of biofouling.
Isothiazolone is a broad-spectrum, highly efficient, low toxicity, non oxidizing biocide. Widely used in industries such as oil fields, papermaking, pesticides, cutting oils, leather, inks, dyes, and leather making.
Notes: 2%, 4% and 8% or any concentration can be supplied on demands.

Usage method
When using isothiazolinone type 2 products as clay stripping agents, the dosage should be 150-300mg/l; When used as a fungicide, it should be added every 3-7 days at a dosage of 80-100mg/L. Can be used simultaneously with oxidizing disinfectants such as chlorine gas, but cannot be used in cooling water systems containing sulfides. The composite use of isothiazolinone quaternary ammonium salts has a better effect.
When using isothiazolinone as an industrial fungicide and mold inhibitor, the general concentration is 0.05-0.4%
Packaging and Storage
Packaging of isothiazolinone in plastic drums, 25kg per drum or determined according to user requirements; Store indoors in a cool and shady place, with a shelf life of ten months.
safety protection
Isothiazolone is corrosive and irritating to the skin and eyes. Protective goggles and rubber gloves should be worn during operation. Once it comes into contact with the skin or eyes, it should be immediately rinsed with plenty of water.
