Isothiazolinones
【CAS】26172-55-4, 2682-20-4 Molecular weight: 115.16
Properties: Isothiazolinones is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out through breaking the bond between bacteria algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones has strong inhibition biocidal effects ondinary bacteria, fungi alga, has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.
Isothiazolinones can mix with chlorine most cation, anion, non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.
Isothiazolinones is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity non-oxidative, it is the ideal biocidal in industrial circulating cool water system in wastewater treatment in oilfield, papermaking, pesticide, cutting oil, leather, detergent cosmetics etc..
Specification: Notes: 2%, 4% 8% any concentration can be supplied on demands.

Usage: When used as sludge stripper fgrade II, the dosage of 150-300mg/L is preferred, when used as boicide, the dosage of 80-100mg/L is preferred,ges every 3-7 days. No used together with oxidative fungicidal such as chlorine, no used in cooling water system containing sulfur. 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.
