Isothiazolinone, CMIT/MIT

Categories: ,

Properties:

Isothiazolinone is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMIT) and 2-methyl-4-thiazoline-3-ketone (MIT). The bactericidal effect of Isothiazolinones is carried out by breaking the bond between bacteria and algae protein. When contacted with microbes, isothiazolinone can quickly inhibit their growth, thus leading to the death of these microbes. Isothiazolinone has strong inhibition and biocidal effects on ordinary bacteria, fungi, and alga. And isothiazolinone (CMIT/MIT) has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation.

Isothiazolinone can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at a high dosage, its biosludge stripping effect is excellent.

Isothiazolinone is a kind of fungicidal with properties of broad-spectrum, high efficiency, low toxicity, and non-oxidative. It is the ideal biocidal in industrial circulating cool water systems and in wastewater treatment in the oilfield, papermaking, pesticide, cutting oil, leather, detergent, and cosmetics, etc.

Uses:

When used as sludge stripper for grade II of isothiazolinone, the dosage of 150-300mg/L is preferred. When used as biocides, the dosage of 80-100mg/L is preferred and charges every 3-7 days. No used together with oxidative fungicidal. Such as chlorine. And no used in cooling water system containing sulfur. When used together with the quaternary amine, the effect will be better. When the CMIT/MIT used as an industrial fungicide, the dosage of 0.05-0.4% is preferred.

Packing and Storage:

25kg in plastic barrel, or confirmed by clients. Storage for ten months in room shady and dry place.

Safety Protection:

The isothiazolinone danger is corrosive. People should avoid contact with eyes and skin. Wear splash-resistant safety goggles and rubber gloves. Once contacted, flush with water.
