Derkemp Mat P is a liquid degreaser for spray applications that can be used on various types of materials such as iron, steel, cast iron, aluminum and non-ferrous metals.

The solutions of Derkemp Mat P, if not rinsed, produce a thin invisible and water-soluble protective film on the surfaces.
The protection is for medium-short times in a covered warehouse, the duration is conditioned by variables such as:

  • the quality of the material,
  • the environmental conditions,
  • the quality of the water used.

If necessary, the residues left by the solutions of Derkemp Mat P can be removed from a good rinse with only water even after weeks from application.

Derkemp Mat P is totally free of silicates and can therefore be used for the greasing of aluminum surfaces that subsequently have to undergo conversion or oxidation treatments.

The solutions of Derkemp Mat P don’t produce foam even in situations of great turbulence.

The concentrations can be easily controlled by means of a specific kit for easy and safe use.
