The prevention of theft of diesel that has had the tax paid is now a major concern. One method of securing your fuel is to dye it a different colour.

FastColours are able to offer a range of Solvent powder dyes that can fulfil this role. Typical application levels would be 10-100 ppm, the higher the amount will give a stronger colour. The dyes are extremely pure (98%+ dye content). They require pre-dissolving in fuel as they are in powdered form. The best way to use them is to make a concentrated solution by dissolving a known weight into some fuel and then add the dye in liquid form to suit your requirements. The dyes can be mixed together to produce many different colours.

Dyeguard Range
FastColours offers the following three products from John Hogg, the specialist in fuel markers.

Dyeguard Blue 79K
Gives a very distinctive blue colour and so acts as a visual deterrent. It is suitable for all types of fuel and is approved by HMRC. However, you must still inform HMRC that you have added this product to your fuel. Typical applications levels are between 25 and 100 ppm, 1 litre dyes between 10,000 and 40,000 litres of fuel.

Dyeguard Black K
Used in oils and lubricants and gives a black colour that acts as a visual deterrent. It is suitable for all types of oils and lubricants, but it is essential that you check before committing to use it in large volumes. Dyeguard Black K must not to be used in the United Kingdom in fuel/diesel/heating oil as it has not been approved by HMRC. For other countries you would need to check on a local basis.

Dyeguard Marker IG and Dyeguard Developer D3 Dyeguard Marker IG
has been specially formulated to detect fuel and oil theft. It is completely colourless in use. However, on addition of a Dyeguard Developer D3, the fuel/oil changes to a strong bluish-green colour.

Due to the nature of the Dyeguard Range, they are only for general sale in UK and Western EU countries. For other countries outside these areas, please get in touch and we will be happy to advise further.
