MERGAL K9N (Fuel Biocide)


Mergal K9N is a broad-spectrum microbicide that is effective in oil based and aqueous systems. The product is a broad spectrum wet-state preservative, used to avoid deterioration and degradation of aqueous systems caused by bacteria , fungi and yeast.


The product is useful for the wet-state protection of various waterborne end-use products, stuccos, polymer dispersions, adhesives, sealants, inks, detergents, household cleaners and similar products, pigment slurries and other industrial applications. Further it is suitable for metalworking-fluids as post-treatment. In practice it is either used in formaldehyde-free systems or if an adaption occurs against pure formaldehyde adducts.

It is especially ideal to boost efficacy in combination with other in-can preservatives. The product is suitable for sanitization of microbial spoiled material.

The product is usually suitable for use under the following conditions:

•pH between 3-9

•Temperatures up to 60°C


Typical dose rates are for Mergal K9N:

• To control growth in fuels (i.e as a regular preventative dose: 0.01-0.05% (100-500ppm) or 0.1 to 0.5Ltrs biocide per 1000Ltrs fuel.

• To treat heavily spoilt fuel and kill existing infection: 0.10-0.25% (1000-2500ppm) or 1 to 2.5Ltrs per 1000ltrs fuel.

It is very important to get thorough mixing and thorough distribution to all areas of the fuel tank. Adding all the biocide in one lot is not recommended as it may result in uneven distribution. A dosing/metering pump is best if the fuel cannot be circulated around the tank.
