The effective component of DSBF-390 isIsothiazolinones compound, it is a new biocide recognized as an effective and low-toxic one in the whole world. DSBF-390 has a strong sterilizing and inhibitory effect on sulfate reducing bacteria, sludge forming bacteria, iron oxidizing bacteria, molds, yeasts and algae. It’s widely used in smelting, oilfield flooding, thermal power, paper-manufacture, oil refining, chemicals, textile, industry cleaning, cutting oil, water based coatings and daily-chemicals etc.

Structural Formula


2-methyl-4-thiazoline-3-ketone(MI)        5-chloro- methyl-4-thiazoline-3-ketone(CMI)
Isothiazolinones is 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 through breaking the bond between bacteria and algae protein. When contacted with microbes, Isothiazolinones can quickly inhibit their growth, thus leading to death of these microbes. Isothiazolinones 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.

Application Method
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. No used together with oxidative fungicidal such as chlorine, and no used 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.
Package and Storage
200kg in galvanized iron drum, or confirmed by clients. Stored in cool, shady and dry place for 10 months.
Safety Protection
Corrosive. Avoid contact with eyes and skin. Wear splash resistant safety goggles and rubber glores. Once contacted, flush with water.
