Dry Moly Lubricant - Molybdenum Disulfide (MoS2) Powder

MoS2 Lubricant · Moly Powder · Molybdenum Disulfide Powder

Molybdenum disulfide powder, commonly known as MoS2 powder, moly powder or dry moly lubricant, is a gray, dry/solid lubricant with chemical formula MoS2 and a hexagonal, lamellar crystal structure. Its layered structure allows the production of low friction coatings on suitable surfaces.

Lowerfriction is a molybdenum disulfide powder supplier for industrial lubrication and laboratory research. The powder is used for dry lubrication and as an additive raw material in suitable grease and oil systems, coatings and polymers, as well as for cold metal forming and vacuum applications.

Performance Note: Lubrication performance is a function of particle size, surface preparation, carrier medium, humidity, load, temperature and operating environment. This attribute should be validated technically before publishing or used in production since the brochure and SDS provide conflicting values for melting or decomposition.

Industrial Applications of MoS2 Lubricant Powder

Application	How MoS2 Powder Is Used	Selection Note
Dry and solid lubrication	Applied dry or used to generate a solid lubricating layer on appropriate surfaces.	Confirm the surface preparation, humidity, load and operating temperature.
Grease and oil additives	Added to suitable grease and oil systems to improve lubricity and load bearing capacity.	Check dispersion, carrier compatibility and performance of final formulation.
Cold metal forming and extreme pressure	Used when a dry lubricant coating and excellent load-bearing capabilities are needed.	Do process trials for substrate, pressure and application technique.
High vacuum and inert atmospheres	Recommended when traditional liquid lubricants may move, evaporate or are not suited.	Check pressure, atmosphere, temperature and compatibility of components.
Paints, coatings and polymers	Additive for suitable coatings, paints, polymers and other solid systems to decrease friction.	Select particle size based on film thickness, surface polish, and dispersion process.
Laboratory and research use	Used in research on lubricant behavior, coatings and chosen material applications.	Check grade, particle size, documentation and handling controls before use.

Choosing an MoS2 Powder Grade

Particle size influences the dispersion, the coating thickness, the surface quality and the processing behavior. The brochure lists a finest size of 90 nm, with 1.5, 4.5 and 12.5 micron grades being progressively coarser alternatives. The final choice should include the carrier medium, substrate, application process, film thickness, operational environment, temperature, load and target amount.
