THE WS2 ADVANTAGE

WS2 . . . . A MODIFIED TUNGSTEN DISULFIDE COATING THAT PROVIDES EXCEPTIONAL LUBRICITY AND WEARLIFE.

APPLICATION PROCESS - WS2 is impinged upon the substrate at ambient temperature. It is applied to any metal without binders or chemical agents. It will not flake, chip or peel because it becomes part of the substrate.

COATING THICKNESS - WS2 is .5 microns thick maintaining the dimensional integrity of the substrate. It's inherent molecular shape and particle size prevent it from building thicker. The coating is blue-gray in color and resembles a rhodium finish. It will mirror back all the characteristics of the substrate.

COEFFICIENT OF FRICTION - WS2 achieves a dynamic coefficient of .030 and static .070 to .090. Pressure, surface finish and surface hardness will effect these results. Extensive real time, real life wear indicates little change over time unless severe overload conditions are introduced.

OPERATING RANGE - WS2 operates from -460 to 1200 degrees F in normal atmosphere and 2400 degrees F in vacuum. At approximately 825 degrees F there is an oxidation threshold and the rate is quite slow compared to other lubricants. Out-gassing characteristics are quite low too.

CHEMICAL STABILITY - WS2 is inert, non-toxic, and non-corrosive. WS2 can be applied to all stable metal substrates. It is impervious to most solvents, refined fuels, and chlorinated solvents. It is attached by fluorine gasses, sulfuric and hydrofluoric acids and hot, caustic alkaline solutions. WS2 is resistant to corrosion but can not inhibit the effect of corrosion on inherently low resistance materials.

COMPATIBILITY - WS2 is used successfully with petrochemical oils and greases, synthetic diesters oils, silicone lubricants and hydraulic fluids. It has an affinity for lubricants and strives to maintain a hydro dynamic layer.
