Isothiazolinones

1, Properties and Usage : 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 . Isothiazolinones can mix with chlorine and most cation ,anion , and non-ionic surfactants . When used at high dosage , its biosludge stripping effect is excellent . Isothiazolinones 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 system and in wastewater treatment in oilfield , papermaking , pesticide , cutting oil , leather , detergent and cosmetics etc . 2, Specification : I temsIndexGrade IGrade IIAppearance Amber transparent liquidlight yellow or light green transparent liquidActive content % ≥ 14.01.50PH value (as it ) 1.0-4.02.0-5.0CM/MI (wt %) 2.5-4.02.5-4.0Density (20°C)g/cm ≥ 1.251.02Note : 2% , 4% and 8% or any concentration can be supplied on demand . 3, Using 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 charge 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 . 4, Package and Storage : 25kg in plastic barrel , or confirmed by clients , Storage for ten months in room shady and dry place . 5, Safety Protection : Corrosive , Avoid contact with eye and skin , Wear splash resistant safety goggles and rubber glores . once contacted , flush with water .
