Abstract:Isothiazolinone derivatives refers to a series of compounds containing isothiazolinone ring, is a new class of broad-spectrum high-efficiency non-oxidizing bactericides, especially DCOIT(4,5-Dichloro-2-octyl-isothiazolone, CAS：64359-81-5), because of its high efficiency, environmental friendliness and broad spectrum advantages, so widely used in polyethylene, polyurethane, leather, paint, coatings, sewage, paper, wood, adhesives, ink and other fields.

Keywords:DCOIT;4,5-Dichloro-2-octyl-isothiazolone;isothiazolinone;CAS:64359-81-5;anti-mildew;antibacterial

1.Product overview

DCOIT(4,5-Dichloro-2-octyl-isothiazolone, CAS：64359-81-5) can be widely used in polyethylene, polyurethane, leather, paint, coatings, sewage, paper, wood, adhesives, ink and other fields. It can replace compounds such as toxic organoarsenic.

2.Performance characteristics

2.1, Efficient anti-mildew anti-algae agent, has special effects on bacteria and algae.

2.2, Low solubility in water, so the effect is long-lasting.

2.3, Suitable for a wide range of pH, heat stability, easy to use.

2.4,Low toxicity, no accumulation in the environment, can be degraded.

2.5,Stable under strong ultraviolet and acid rain conditions.

2.6, Excellent slow-release technology, a broad spectrum of fungi, algae and other microorganisms, and reject Marine life.

2.7. No heavy metals. When released into the environment, it will penetrate into the sediment and decompose, so it does not accumulate in Marine life;

2.8, Stable in Marine paint, provide lasting protection, and the effect is better than TBTO.

3.Specific indicators

4.Application field

DCOIT(4,5-Dichloro-2-octyl-isothiazolone, CAS：64359-81-5) is generally used as an antibacterial agent and a preservative, which can effectively kill cyanobacteria, basidiomycetes, Aspergillus Niger, Fusarium, Curvularia, Viridis viridis, etc., polythymus polythymus, P. viridis, P. viridis, etc.

5.Usage and dosage

WhenDCOIT(4,5-Dichloro-2-octyl-isothiazolone, CAS：64359-81-5) is used as a fungicide, it is recommended to use a concentration of 0.1% to 0.5%, and the amount of use depends on the actual situation. This product is used in the field of sterilization and mildew prevention of interior and exterior latex paint, the recommended amount of addition is 0.1 ~ 0.3%, the specific amount depends on the performance of the coating product and the use environment.

The use of DCOIT(4,5-Dichloro-2-octyl-isothiazolone, CAS：64359-81-5) in the field of antifouling: it is recommended to use a concentration of 0.2% to 0.5%, DCOIT as an antifouling agent has the characteristics of high efficiency, low toxicity, long duration of drug effect and environmental safety, and is an excellent substitute for organotin antifouling agen.
