Our brand names of  Dyeguard ® and  Sudan®  are recognized world wide .

We manufacture liquid solvent soluble dyes, which are sold under both of the above brands,  in a choice of carrier solvents, which are  suitable for use in  all types of fuels, oils, greases, lubricants and  waxes.
These dyes have consistent colour strength  low  content of insolubles, and  remain  fluid and pourable down to  sub-zero temperatures.
