MOLYKOTE® Z Powder – MoS₂ Solid Lubricant for Extreme Applications

Dry Solid Lubrication for Demanding Applications

MOLYKOTE® Z Powder is supplied as a free-flowing, charcoal-gray to black powder based on molybdenum disulfide. With a typical MoS₂ purity of 98%, it can form a solid lubricating layer on suitable metal surfaces without relying on a conventional liquid oil film.

This makes it particularly interesting for applications where grease contamination, oil evaporation or limited lubricant access can be a concern.

Suitable for Heavy Loads and Low-Speed Movement

One of the key advantages of MoS₂ solid lubrication is its suitability for high-load and low-speed contact conditions. MOLYKOTE Z Powder can be used as a dry-burnished lubricant on metallic contact surfaces and as a running-in aid for press-fit assemblies.

Typical application areas include:

• Press-fit components and interference assemblies
• Sliding metal contacts
• Bushings, bearings and sleeves
• Self-lubricating plastic components
• Sintered-metal parts
• Metalworking compounds
• Brake lining formulations
• Heavy-load, low-speed mechanisms

Wide Temperature Capability

Temperature performance is another reason to consider a solid lubricant powder for severe industrial environments. The current technical data lists a service temperature range of approximately −185°C to 400°C, with use in vacuum conditions reported up to approximately 1,100°C.

This broad operating range makes MOLYKOTE Z Powder relevant to specialized equipment exposed to temperature extremes, vacuum conditions or environments where conventional lubricant films may become less effective.

More Than a Dry Lubricating Film

MOLYKOTE Z Powder can also be incorporated into other materials and formulations rather than being used only as a surface-applied powder. Potential uses include self-lubricating plastics, sintered-metal components and metalworking formulations.

For manufacturers developing friction-reducing materials or components, MoS₂ powder can therefore serve as a functional solid-lubricant additive as well as a dry-film lubrication material.

Product Information

Technical values are typical data and should be checked against the latest manufacturer documentation for specific applications.

Conclusion

For industrial components operating under heavy loads, low speeds, high temperatures or difficult lubrication conditions, MOLYKOTE Z Powder provides a practical MoS₂-based solid lubrication solution. Its dry-film capability and broad application range make it worth considering for metal assemblies, self-lubricating materials, press-fit components and other specialized industrial applications.
