Isothiazolinones
Isothiazolinones
【CAS】26172-55-4,2682-20-4 Molecular weight: 115.16
Properties: Isothiazolinonesis composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect ofIsothiazolinones is carried out through breaking the bond betweenbacteria and algae protein. When contacted with microbes,Isothiazolinones can quickly inhibit their growth, thus leading todeath of these microbes. Isothiazolinones has strong inhibition andbiocidal effects on ordinary bacteria, fungi and alga, and has manyadvantages such as high biocidal efficiency, good degradation, noresidual, safety in operation, good compatibleness, goodstabilization, low cost in operation.
Isothiazolinones can mix with chlorine and most cation, anion, andnon-ionic surfactants. When used at high dosage, its biosludgestripping effect is excellent.
Isothiazolinones is a kind of fungicidal with properties of broadspectrum, high efficiency, low toxicity and non-oxidative, it isthe ideal biocidal in industrial circulating cool water system andin wastewater treatment in oilfield, papermaking, pesticide,cutting oil, leather, detergent and cosmetics etc..
Specification: Notes:2%, 4% and 8% or any concentration can be supplied on demands.
Package and Storage: 25kg inplastic barrel, or confirmed by clients. Storage for ten months inroom shady and dry place.Usage: When used assludge stripper for grade II, the dosage of 150-300mg/L ispreferred, when used as boicide, the dosage of 80-100mg/L ispreferred, and charges every 3-7 days. No used together withoxidative fungicidal such as chlorine, and no used in cooling watersystem containing sulfur. When used together with quaternary amine,the effect will be better. When used as industrial fungicide, thedosage of 0.05-0.4% is preferred.
SafetyProtection: Corrosive, Avoid contact with eye and skin, Wearsplash resistant safety goggles and rubber glores.once contacted,flush with water.
