Kathon FP Changes

There are a range of changes occurring concerning fuel biocide legislation in the U.K. and Europe and as a consequence, commercial changes to Kathon™ FP 1.5 pricing, availability & distribution.

Firstly, Kathon™ FP 1.5 will no longer available for aviation use with immediate effect. Aviation users should refer to their Aircraft Maintenance Manual/OEM for advice on how to proceed with fuel contamination issues or contact their Silmid Account Manager.

In addition, the manufacturers of Kathon™ FP 1.5 have granted Fuelcare an own brand biocide 'FuelClear MB15' within their CMIT/MIT biocidal product family (under the European Union Biocides Products Regulations). This means FuelClear MB15 is now available as a low price, union-authorised fuel biocide - one of the only fuel biocides available throughout Europe with a tried & trusted fuel biocide chemistry, E.U. & U.K. national approvals as well as coming from a company with 40 years' of fuel biocide experience and expert technical assistance.

  • FuelClear MB15 is now available for sale for our non-aviation fuels customers. Fuelcare are seeking aviation approval for this product in due course.
  • FuelClear MB15 has the same characteristics as Kathon™ FP 1.5.
  • FuelClear MB15 is the same chemical, made in the same manufacturing facility with the same Quality Assurance as Kathon™ FP 1.5.
  • Non-aviation (i.e. diesel, gas oils, kerosene, gasoline) biocide approvals will be transferred from Kathon™ FP 1.5 to FuelClear MB15 in the coming 12 months which will be confirmed with each O.E.M.
  • FuelClear MB15 contains the same active ingredient CMIT/MIT as Kathon™ FP 1.5 in the same proportion to solvent Glycol. Both active ingredient and tradename (FuelClear MB15) have been notified under the E.U. Biocides Products Regulations (B.P.R.). The active ingredient is now fully approved and the final dossier will be available shortly. All non-aviation Kathon™ FP 1.5 will be moved to FuelClear MB15 unless specific approvals are required (i.e. military)

Kathon™ FP 1.5 will still be available for sale but will effectively be a premium product. Kathon™ FP 1.5 (as the trade name) and ‘CMIT/MIT’ (active ingredient) have been notified and a dossier submitted for 'Union Authorisation' i.e. the ability sell anywhere within the E.U. The supply & sale of Kathon™ FP 1.5 Fuel Biocide is therefore currently (March, 2020) in a transition period with pricing, availability and distribution arrangements in flux.
