MI/CMI is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-k etone (MI). The bactericidal effect of MI/CMI is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes,MI/CMI can quickly inhibit their growth, thus leading to death of these microbes.MI/CMI has strong inhibition and biocidal effects on ordinary bacteria, fungi and alga, and has many advantages such as high biocidal efficiency, good degradation, no residual, safety in operation, good compatibleness, good stabilization, low cost in operation. MI/CMI can mix with chlorine and most cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is excellent.

When used as sludge stripper for grade II, the dosage of 150-300mg/L is preferred. When used as boicide, the dosage of 80-100mg/L is preferred, and charges every 3-7 days. MI/CMI can be used together with oxidative fungicide such as chlorine, but not 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.
Corrosive, irritating to eyes and skin, avoid contact with eye and skin. In case of contact, flush with clean water or soapy water immediately for at least15 minutes and seek for medical advice. During operation, protected with safety goggles and rubber gloves.
25kg net in plastic drum, or as customers’ requirement. Storage for twelve months in shady and cool room with good ventilation.
