Tungsten Disulfide (WS2) is a low friction dry lubricant coating that improves performance and service life better than other dry lubricants by reducing friction & noise, improving mold release, and solving problems of excessive wear, seizing, galling and fretting. The Tungsten Disulfide coating service process is done with pressurized air that impinges a dry metallic coating without heat, binders or adhesives. The lubricant coating bonds instantly to any metal or resin substrate with a thickness of 0.00002″ (1/2 micron). Buy Tungsten Disulfide powder

Benefits and Capabilities of Tungsten Disulfide (WS2)
- The WS2 low friction coating overcomes or reduces mechanical lubrication problems which improve performance and extend service life.
- Reduces friction to lower emissions as less fuel is used for a given power level when applied to engine parts such as pistons rings, cams and bores.
- Eliminates and reduces costly maintenance problems that cause breakdowns and expensive downtime by stopping galling, fretting and friction caused by dissimilar metals and their different hardness factors.
- Maintains the dimensional integrity of the substrate to within 1/2 micron with no build-up. Tungsten Disulfide (WS2) particles will not adhere to themselves so the coating thickness is limited to 1/2 micron.
- Withstands loads to 100,000 psi (or load capacity equal to substrate) and operates in the temperature range of -460°F to 1200°F (-273°C to 650°C). Buy Tungsten Disulfide powder
- Offers 100% Lubricity throughout its texture.
- Is inert, inorganic, non-toxic, non-distortive, non-corrosive and resistant to most fuels solvents. It is compatible with and enhances the performance of all oils and greases.
- Resists carbon build-up due to its extremely low co-efficient of friction, less than half that of graphite, Moly (MoS2) and Teflon.
- Molecularly bonds to all materials and platings and can only be eliminated by removing the bonded substrate.
- No bakeout or heat curing is required for the application of Tungsten Disulfide (WS2). Buy Tungsten Disulfide powder
Tungsten Disulfide combination coatings for additional wear & corrosion protection.
- Chrome or Electroless Nickel with Tungsten Disulfide (WS2)
- Provides additional wear protection from the 70Rc hardness of the chrome or EN and the low friction of Tungsten Disulfide.
-
Anodizing with Tungsten Disulfide (WS2)
- Provides aluminum with more corrosion and wear protection with low friction from Tungsten Disulfide.
-
Chromium Nitride (CrN) combined with Tungsten Disulfide (WS2).
- The thin hard coating of PVD applied CrN combined with Tungsten Disulfide provides a thin hard film with a very low friction factor which address stamping tooling and wear components in assembly and packaging machines. Buy Tungsten Disulfide powder
Tungsten Disulfide (WS2) Care Instructions:
Tungsten Disulfide (WS2) is a durable coating and normally does not need to be recoated for approximately one year. Glass filled or talc filled resins of 30% or more will reduce the life of the coating because of their abrasive nature. To protect your items coated with Tungsten Disulfide (WS2):
- Cleaning solvents such as trichlorethane, acetone, mineral spirits or alcohol can be used with no adverse affects. Strong alkaline solutions or acids cannot be used.
- Tungsten Disulfide (WS2) is compatible with all mold saver type products. We do recommend that a corrosion protector be used on molding surfaces during storage. Buy Tungsten Disulfide powder

Since the powder offers one of the lowest Coefficient of Friction (Dynamic @ 0.03 & Static @ 0.07), the applications are unlimited and could be tried with every conceivable idea. .
Two established ways the WS2 powder can be used are:
1) Mixing the WS2 powder with wet lubricants (such as oil, grease & other synthetic lubricants):
The powder can be mixed 1wt% to 15wt% (as required) with grease or oil. This will enhance lubricity of the mixture and also improves High Temperature and Extreme Pressure properties of mixture. During the use, WS2 in the mixture will get coated on mating/moving parts, which in turn reduces friction and improves lubricity and load bearing ability for much longer cycles. Buy Tungsten Disulfide powder2) Coating the WS2 powder on a substrate requiring (dry) lubricity:
The powder can be coated by spraying (at 120 psi) the substrate with dry (& cool) pneumatic air. It does not require any binders and spraying can be done at normal room temperature. Coated film will be 0.5 micron thick. In an alternative application method, the powder can also be mixed with Isopropyl alcohol and this paste could be buffed to the substrate. The coating applications are already established in many areas such as Automotive parts, Racing Car Engine and other parts, Aerospace parts, Bearings (Linear, Ball, Roller etc), Shafts, Marine parts, Cutting Tools, Blades, Slitters, Knives, Mold release, Precision Gears, Valve components, Pistons, Chains, Machinery components and many other areas.
