  • Specially formulated to reduce wear.
  • Protects tools, extending their lifetime.
  • Should be used in the following processes: Drawing Deep drawing, Stamping.
  • Applicable materials: Steel, Stainless Steel, Copper.
  • Has excellent ultra-pressure protection, prevents welding of the work pieces.
  • Excellent cooling and lubrication involving high quality surface finishes.
  • Easily removed, will not stain steel.
  • Has a mild non-offensive odor, will not smoke.

NanoLub® is based on NIS’ unique patented technology using solid tungsten disulfide (WS₂) multilayered nano fullerene-like particles. These unique multi-layer IF-WS2 nano-spheres are well-known to show outstanding temperature (-270 °C to 450 °C), shock (5,076,000 PSI) and pressure (4,263,000 PSI) resistance and renders them to be versatile under extreme operating conditions including high and ultra-low temperatures, high pressure and high vacuum, high load, high rotating speed, high radiation and corrosion conditions.


Due to its size (50-200 nm) and morphology of IF-WS₂ nanoparticles, they easily fill the asperities and irregular surface of the metals providing excellent load bearing and anti-wear properties. Under high loads (>1 GPa), the layers peels from the spheres forming a thin protective monolayer of WS₂ on the surface of the metal thereby reducing friction and wear between the metals.
