Isothiazolinones [CAS No.] 26172-55-4, 2682-20-4 Molecular weight: 115.16 Properties: This product is composed of 5-chloro-2-methyl-4-thiazoline-3-ketone (CMI) and 2-methyl-4-thiazoline-3-ketone (MI). The bactericidal effect of this product is carried out through breaking the bond between bacteria and algae protein. When contacted with microbes, this product can quickly inhibit their growth, thus leading to death of these microbes. It can quickly penetrate the biomembrane adhesive on surface of cooling water column, leading to the stripping of these sludges. Therefore, this product 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. This product can mix with chlorine and many cation, anion, and non-ionic surfactants. When used at high dosage, its biosludge stripping effect is obvious. This product is a kind of fungicidal with properties of broad spectrum, high efficiency, low toxicity and non-oxidative, and is the ideal biocidal in industrial circulating cool water system and in wastewater treatment in fields such as oilfield, papermaking, pesticide, cutting oil, leather, detergent and cosmetics. Specification: Meet criterion of HG/T3657-1999 Notes: 2%, 4% and 8% or any concentration can be made according to requirements items index Class I Class II Appearance Brown transparent liquid Light yellow or light green transparent liquid Active content ％ ≥ 14.0 1.50 pH (1%water solution) 2.0-4.0 2.0-5.0 Density （20℃）g/cm3 ≥ 1.30 1.02 Usage Methods: When used as sludge stripper, the dosage of 150-300mg/L is preferred, when used as fungicidal, 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 use in cooling water system containing sulfur. When used together with quaternary amine, the effect will be better. Package and Storage: 25kg in plastic barrel, or confirmed by clients. Storage for ten months in room shady and dry place. Safety Protection: Corrosive, Avoid contact with eye and skin, once contacted, flush with water.
