Areas of application

  • Lubricating oil additive for heavily loaded friction and rolling bearings for increasing the lubricating effect, improving the high-pressure properties and reducing the temperature increase
  • Gear oil additive to guard against gearwheel damage Stops pitting and is especially suitable for gearbox designs with a high percentage of sliding
  • Engine and compressor oil additive for reduced wear and increased operating safety, as run-in and smoothing lubricant
  • Machining oil additive for chip-free or cutting production to increase working speeds and tool life

Advantages and benefits

  • Excellently suited as performance-increasing additive, as additive to bed track oils, engine oils, C/CC oils and slightly alloyed industrial oils
  • Highly effective due to finest, homogeneous MoS₂ distribution in the oil
  • Broad range of uses with many different oils and alone as a high-performance oil
  • Lowest friction due to high lubricating effectiveness of MoS2
  • Fully stabilised without precipitation, passes through common micro-filters, does not react to magnetic filters

Technical specifications

  • density (at 20°C): 0.92 g/cm³
  • viscosity at (40°C): approx. 90 mm²/s


Shake or stir well before use. Depending on loading, add 1-2% to engine oils and 5-10% to machine- and gear oils. Instructions of the machine manufacturer have to be observed.
