Overview

The effectiveness of Kathon™ has been proven over a number of years and it has extensive approvals endorsing its use in a wide range of fuel types. Kathon™ combines exceptional activity with broad spectrum performance. Consequently it is effective at very low use levels against all commonly occurring fuel contaminants (bacteria, fungi and yeast). Furthermore, the active ingredients of Kathon™ are non-persistent in the environment, giving the product good environmental acceptability.

IMPORTANT UPDATE: Kathon FP 1.5 Fuel Biocide is being rebranded as Kathon Fuel 15 shortly. Kathon Fuel Biocide is also being discontinued for aviation applications with immediate effect. For further information please contact us [email protected]

How does Kathon™ Fuel 15 work?

Kathon™ Fuel 15 works by eliminating the often deep emulsion layer at the fuel/water interface. This will facilitate water removal by draining or by the fuel line separator. It is this emulsion that is often the critical problem when it enters the fuel line after fuel contents of a tank are disturbed or shaken.

Fuel treated with Kathon™ will remain protected from contamination over extended periods of time. It will also resist contamination if re-inoculated from other sources during storage or transport. Kathon™ has outstanding performance in a variety of applications & has wide ranging approvals and endorsements.

Specifications

Kathon™ Fuel 15 Fuel Biocide (formerly Kathon™ FP 1.5) contains a 3:1 ratio mixture of 5-chloro-2-methyl-3(2H)isothiazolone and 2-methyl-3(2H)isothiazolone (CAS N°55965-84-9), (abbreviated name CMIT/MIT). Kathon is a solution of the technical grade of the active ingredient, CMIT/MIT, in dipropylene glycol at a nominal value of 1.5% of active substance. This biocidal substance has been notified under the Biocidal Products Directive (BPD; notification # 408) and is registered with the United States Environmental Protection Agency (US EPA).

Kathon™ is effective at low use levels, against microbial species commonly encountered in fuel systems, including bacteria, yeast, and mold. Kathon™ is designed to cause inhibition of microbial growth upon contact, and quickly result in cell death. The exact time to kill all microbes in a fuel will vary, but will typically be between 6 and 36 hours.

Kathon™ FP 1.5 is effective in systems containing both fuel and water. Unlike other fuel treatment biocides, the active ingredients in Kathon™ FP 1.5 are not deactivated by water.

Applications

Water and sludge should be removed from fuel tanks before application of biocide and again after the retention period. Kathon™ Fuel 15 Fuel Biocide (formerly Kathon™ FP 1.5) has been tested and found effective in a wide range of fuels, including diesel, petrol, ULSD, biodiesel, kerosene, gasoline, and other fuels used in marine, aviation, automotive and home heating applications.

Kathon™ is typically dosed at 200 to 300 ppm (200ml to 300ml per 1000L fuel) for curative treatment (i.e. when there is evidence of bacterial contamination). A minimum residence time of 12 hours should be allowed, before the fuel is used, though 24 hours is recommended. The biocide should be added in such a manner so as to allow good mixing uniform distribution of the biocide across the fuel.

Kathon™ can also be used as a preventative/maintenance measure (to guard against bacterial contamination) in fuels that lack microbial contamination. For such a use, the recommended dosage is 100 to 150 ppm (100-150mL per 1000L fuel). The biocide should be added in such a manner so as to allow good mixing and uniform distribution of the biocide across the fuel. In such a case the residence time should still be at least 12 hours. Extreme care must be taken to avoid the addition of a preventative/maintenance level dosage of Kathon™ to a heavily contaminated fuel system.

Kathon™ can also be used as a shock biocide, for fuels that are heavily contaminated. If this is the case, doses up to 1000 ppm can be administered (1L biocide per 1000L fuel) according to the BPD. The US EPA allows the use of up to 400 ppm Kathon™ in heavily contaminated fuel systems (400ml biocide per 1000L fuel). In this case, the residence time is recommended to be a full 24 hours.

Features and Benefits

Kathon™ Fuel 15 Fuel Biocide (formerly Kathon™ FP 1.5) has wide ranging approvals in marine, automotive, home heating and military fuels. It is registered with the EPA as a fuel biocide and is used very successfully worldwide.

Broad Spectrum Activity: Kathon™ is effective at very low use levels against microbial species (bacteria, fungi, yeasts) commonly encountered in fuel systems. Full details of minimum inhibitory concentration value of Kathon™ against a range of microorganisms can be found on page 8 of the main technical bulletin.

Rapid Inhibition of Microbial Growth: Kathon™ causes immediate inhibition of growth on coming into contact with a microorganism. Growth inhibition rapidly becomes irreversible and results in cell death. The time to achieve eradication varies according to the extent of contamination and the type of microorganisms present. Typically, as the graphs below indicate, within 24 hours of treatment the fuel will again be fit for use.

Long Term Preservation: Fuel treated with Kathon™ will remain protected from contamination over extended periods of time. It will also resist contamination if reinoculated from another source. In studies conducted over an 8 week period, contaminated fuels were treated with fuel biocides. Once microbial control was established, the fuel was reinoculated with microbes, to measure long term protection capability. Kathon™ was not dosed for a second time. The initial dose was still able to protect against bacteria and fungi.

Complete System Protection: The partitioning characteristics of Kathon™ ensure that is it present in both the fuel and water phases. This facilitates eradication of contamination in the water bottom as well as protection of the fuel as it is transferred through the distribution system
