What is Isothiazolinones used for?
Isothiazolinones act by breaking the bonds of bacterial and algal proteins. After contacting with microorganisms, isothiazolones can quickly and irreversibly inhibit their growth, resulting in the death of microbial cells, so they have a strong inhibitory and killing effect on common bacteria, fungi, and algae. It has the characteristics of high biocidal efficiency, good degradability, no residue, safe operation, good compatibility, strong stability, and low cost of use. Compatible with chlorine and most anionic, cationic and nonionic surfactants. At high doses, isothiazolinones have a significant effect on biological slime stripping.
Isothiazolinone is a broad-spectrum, high-efficiency, low-toxicity, non-oxidizing biocide. It is widely used in oil field, paper making, pesticide, cutting oil, leather, ink, dyestuff, tanning and other industries.

The usage of Isothiazolinones?
When used as sludge stripper for grade II, the dosage concentration is 150-300mg/L. When used as fungicides, they are added once every 3-7 days, and the dosage is 80~100mg/L. It can be used simultaneously with oxidizing fungicides such as chlorine, and cannot be used in cooling water systems containing sulfides. When used together with quaternary amine, the effect will be better. When used as industrial fungicide, the dosage of 0.05-0.4% is preferred.
