WS2 Powder · WS2 Dry Lube · Tungsten Disulfide Solid Lubricant

Tungsten disulfide powder, or WS2 powder, is a dry solid lubricant for industrial and laboratory usage. The powder is usually indexed under WS2 lube or WS2 dry lube and can be applied as a thin dry coating or evaluated as an addition in suitable lubricant and material systems.

Lowerfriction provides 0.6 micron tungsten disulfide powder online. Alternative sub-micron, nano and bulk requirements can be reviewed against needed particle size, substrate, operating conditions, and order quantity.

Product availability: The 0.6 micron WS2 powder (MK-WS2-06) is available online. Other sub-micron, nano and bulk supply alternatives are available subject to product and document confirmation.

WS2 dry lube applications

Application	How WS2 powder is used	Selection note
Dry-film lubrication	Can be applied by spraying, buffing or tumbling.	Final performance is affected by surface preparation and film control.
Oil or grease additive testing	Dispersed in a suitable lubricant system.	Check dispersion, filtration and carrier compatibility. The documents supplied do not provide a universal rate of addition.
Vacuum and controlled-environment lubrication	Used where traditional liquid lubricants are not applicable.	Verify substrate, loading, temperature and vacuum conditions.
High-load sliding surfaces	To be applied as a thin layer on suitable parts.	Before introducing the application into production, test it.
Resin, plastic or coating systems	Added to a matching blend to enhance lubricity.	Verify particle size, dispersion, processing conditions and material compatibility.

Choosing a WS2 powder

If you want a sub-micron material for dry-film coating or lubricant-additive assessment, use the 0.6 micron WS2 powder shown. For nano, alternative sub-micron or bulk needs please give the desired particle size, substrate, carrier medium, operating temperature, load, environment and order quantity in order to ensure availability.
