NanoLub® GH-X Lithium EP Grease Additive

NanoLub® GH-X Lithium EP Grease Additive is a new generation surface-reconditioning nano lubricant additive for grease based on NIS’s proprietary super strong tungsten disulfide (WS₂ ) multilayered nano-fullerene particles.



  • Specially formulated to significantly improve performance of Greases used in various Extreme Pressure applications.
  • Superior Extreme Pressure (EP) Anti-Friction (AF) and Anti-Wear (AW) properties.
  • For use in automotive, industrial, mining and heavy equipment, bearings, gears (open gears, closed gears) slideways and various other machine components.
  • Can be used as part of the additives package for lithium greases.

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.
