Molecular Weight:
115.16
Structure Formula:
Properties:
Isothiazolinones are composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of Isothiazolinones is carried out by breaking the bond between bacteria and algae protein; therefore, when in contact with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to the death of these microbes.
Isothiazolinones have strong inhibition and biocidal effects on ordinary bacteria, fungi, and alga. In addition, they have many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, and low cost in operation.
Isothiazolinones can mix with chlorine and most cation, anion, and non-ionic surfactants. However, its bio-sludge stripping effect is excellent when used at high dosages.
Isothiazolinones are a kind of fungicidal with properties of broad-spectrum, high efficiency, low toxicity, and non-oxidative. Therefore, it is the ideal biocidal in industrial circulating cool water systems and wastewater treatment in the oilfield, papermaking, pesticide, cutting oil, leather, detergent, cosmetics, etc.

Usage:
When used as a sludge stripper for grade II, 150~300 mg/L is preferred. When used as a biocide, 80-100mg/L is preferred and charges every 3~7 days. No use with oxidative fungicidal such as chlorine, and no use in a cooling water system containing sulfur. When used together with a quaternary amine, the effect will be better. When used as an industrial fungicide, 0.05~0.4% is preferred.
Packing and Storage:
25kg in plastic barrel, or confirmed by clients.
Storage for ten months in a room shady and dry place.
Safety Protection:
Corrosive, avoid contact with the eyes and skin. Wear splash-resistant safety goggles and rubber gloves. Once contacted, flush with water.
