    MPS contains high concentration of PTFE and Bentonite
  • No water/oil emulsion
    MPS does not emulsify with oil or water.
  • Compatible with most oil types
    Oil is used as a carrier for solid particles, PTFE and Bentonite.
  • Broad working temperature range
    MPS tolerates temperatures – from -30° C to 260° C.

  • MPS contains seal revitalizing additive
    Compatible with FKM and NBR elastomers. MPS restores seals elasticity without swelling.
  • Surface treatment
    MPS polishes surface and fills in cracks of up to 2 mm. MPS provides static lubrication due to surface fluorination.

Can MPS protect against corrosion?

MPS products operate in the environment with the high risk of water contamination. MPS products have been tested in its concentrated form and when used as 10% mix with both mineral and bio-degradable oil.


The results of anti corrosion SKF Water Emcor Test has shown no signs of corrosion even in the presence of 25 per cent of seawater.
