MOLYKOTE Z Powder Molybdenum Disulfide Dry Lubricant

Product Overview

MOLYKOTE Z Powder is a high-purity, free-flowing dry solid lubricant based on molybdenum disulfide (MoS₂). Its fine, dark-gray to charcoal-black particles are designed for applications where a dry lubricating material is preferred over conventional oil or grease.

Molybdenum disulfide helps reduce friction between contacting surfaces and can help prevent direct metal-to-metal contact under suitable operating conditions. MOLYKOTE Z Powder can be applied as a dry-burnished film to compatible metal surfaces or incorporated as a solid lubricant additive into selected engineering materials and industrial compounds.

It is particularly relevant to assembly and run-in applications involving press-fitted components, bushings, sleeves and machinery operating under heavy loads at low speeds. Correct application and surface preparation are important for achieving the intended lubrication performance.

Key Features and Benefits

• High-Purity MoS₂: Composed of molybdenum disulfide, a widely used solid lubricant.

• Free-Flowing Powder: Suitable for controlled handling, surface application and selected compounding processes.

• Fine Particle Size: The supplied product information specifies an approximate particle size of 3–4 µm.

• Dry-Film Lubrication: Can be rubbed or brushed onto compatible metallic contact surfaces to form a dry lubricating layer.

• Anti-Galling Protection: Helps reduce friction, scuffing and the risk of seizure during suitable assembly and run-in operations.

• Heavy-Load, Low-Speed Applications: Useful as an assembly aid where boundary lubrication is required.

• Solid Lubricant Additive: Can be evaluated for use in selected self-lubricating plastics, sintered metal components, elastomers, brake linings and metalworking compounds.

• Broad Temperature Capability: The stated limits vary with the atmosphere and operating conditions; confirm the applicable range before use.

Typical Applications

Dry-Burnished Lubricant Films

MOLYKOTE Z Powder can be rubbed or brushed onto suitable metallic contact surfaces to provide dry lubrication. Potential applications include plain bearings, bushings, sleeves and other sliding interfaces where direct metal-to-metal contact should be minimized.

Press-Fitting and Mechanical Assembly

The powder can be evaluated as an assembly aid for press-fitted parts, tight mechanical connections and other operations where friction, galling or seizure may occur during installation.

Heavy-Load, Low-Speed Run-In

Molybdenum disulfide is commonly used in boundary-lubrication applications. MOLYKOTE Z Powder may be suitable for selected machinery startup and run-in procedures involving heavy loads and low sliding speeds, provided the application method and equipment requirements are appropriate.

Self-Lubricating Plastics and Engineering Materials

Can be considered as a solid lubricant additive in selected polymer formulations and self-lubricating plastic compounds. Confirm compatibility with the base polymer, dispersion requirements and the compound manufacturer's processing specifications.

Sintered Metal Components and Elastomers

May be evaluated as an additive for compatible sintered metal parts and elastomer formulations. Suitability depends on the material system, manufacturing process and required mechanical properties.

Brake Linings and Metalworking Compounds

Can be considered for specific industrial formulations involving brake linings or metalworking compounds. Verify the formulation requirements and applicable performance standards before use.

Application and Handling

• Prepare and clean the substrate according to the requirements of the intended application.

• Apply the powder using a suitable controlled method, such as rubbing or brushing, where a dry-burnished film is required.

• For use as an additive, follow the material manufacturer's formulation, mixing and processing instructions.

• Prevent contamination of sensitive equipment and nearby surfaces during powder handling.

• Avoid generating or inhaling airborne dust. Use appropriate ventilation and personal protective equipment in accordance with the current SDS.

• Do not assume that a loose powder coating provides the same retention or protection as a bonded dry-film coating.

• Consult the current technical data sheet (TDS) and safety data sheet (SDS) for detailed handling, application and storage guidance.

Important Technical Considerations

Temperature and Atmosphere

The supplied information lists a temperature range of -185°C to +400°C under normal conditions and up to +1,100°C in a vacuum. These values require confirmation against the manufacturer's current technical documentation. High-temperature performance depends on the atmosphere, exposure duration, contact conditions and the intended lubrication function.

Application Method

Dry-burnished powder, bonded dry-film coatings and powder blended into a material are different application systems. Confirm that the intended method is supported for the exact product and component.

Material Compatibility

When used as an additive, verify compatibility with the selected plastic, elastomer, sintered metal or compound formulation. The addition of a solid lubricant may affect the finished material's mechanical, electrical or processing properties.

Why Choose MOLYKOTE Z Powder?

MOLYKOTE Z Powder offers a dry molybdenum disulfide lubrication option for selected metal contacts, assembly operations and industrial material formulations. Its fine particle size and solid-lubricant properties make it useful to evaluate where conventional grease or oil is unsuitable, or where a dry lubricant additive is required.

Before selecting the product, confirm the application method, substrate, load, speed, atmosphere and temperature against the current manufacturer documentation.

Important: Verify the exact product designation, particle-size specification, temperature limits and application recommendations using the latest official manufacturer TDS and SDS before publishing technical claims.
