Tungsten Disulfide

Wear and abrasion resistant coatings

Tungsten disulfide (WS2) is applicable to a wide range of industrial, aerospace, medical and automotive applications. Virtually any critical moving part in need of a continuous dry film lubricant will accept and benefit from it. Since it forms a molecular bond with the substrate to which it is applied, it can even be used in high vacuum applications.

In addition, the following properties make it an ideal film for use in medical, dental, and surgical applications:

  • Non-toxic,
  • Inorganic
  • Chemically inert
  • Highly lubricious

Automotive

Widely used in the racing industry and secondary automobile product market, Tungsten Disulfide offers an extremely low coefficient of friction (0.030 dynamic) significantly improves lubricity characteristics and reduces wear on most engine parts. It has been successfully utilized for rack and pinion gears, gearbox components, pistons, camshafts and transmission components.

Aerospace / Aircraft

With a broad operating range between -350° to +1000° F (-188° to +538° C) and low outgassing characteristics, Tungsten disulfide is useful in a wide range of aerospace and aircraft components. The molecular bonded structure is non-migratory, eliminating any potential for particulate contamination. The dimensional buildup of only 0.000020" (0.5 micron) makes the coating ideal for tight tolerance requirements. We certify to all applicable military, customer and industrial specifications.

Mold Release

With operating temperatures between -350 to +1000°F (-188° to +538° C) the WS2 dry film lubrication process will significantly improve part release and material flow for most high density plastics, including; polycarbonate, polyethylene, polypropylene, ABS, polycarbonate and styrene. The improved flow characteristics and part release permit lower temperature and pressure requirements while producing a significant reduction in cycle times. In addition the improved release eliminates or minimizes flash, sticking, scuffing and other blemishes. Tungsten disulfide reduces friction and breakage for ejector pins and improves lubricity and reduces wear on gibs, slides, lifters, leader pins and bushings.

Valve, Pump & Mechanical Components

The sub-micron lamellar crystalline structure creates a complex capillary surface environment aiding in fluid lubrication retention providing significant reduction in wear characteristics. The low coefficient of friction (0.030 dynamic) reduces drag and improves lubricity translating to an increase in performance in most environments.

Bearings & Gears

The sub-micron structure (0.5 micron) is completely uniform with virtually no dimensional change and is an excellent lubricity coating for tight tolerance components such as gear teeth, bearing races, cages and balls. The lamellar crystal structure improves wear characteristics, prevents spalling, reduces friction and noise and is compatible will fluid lubrication. It can be applied to all ferrous and non-ferrous metals.
