MOLYKOTE G-N Metal Assembly Spray is designed for applications where high loads, friction, wear, galling, or fretting can occur. Typical applications include:

• Assembly and run-in of new or rebuilt equipment
• Plain bearings, bushings, and sleeves
• Splines
• Gears and gear mechanisms
• Cams and ways
• Movable screws
• Threaded spindles and lead screws
• Threaded connections and fasteners
• Press-fitting operations
• Slides, guides, and tracks
• High-load and boundary lubrication applications
• Airframe maintenance
• Aircraft engine applications

Product Benefits

• Extreme-pressure lubrication: Helps protect metal surfaces under high-load and boundary lubrication conditions.
• Low friction: Provides a low coefficient of friction immediately after application without burnishing.
• Anti-galling protection: Helps reduce galling, seizing, and excessive friction between metal surfaces.
• Fretting protection: Helps protect against fretting wear and corrosion.
• Running-in performance: Helps reduce frictional forces and surface damage during the running-in of new or rebuilt components.
• Aerosol application: Provides a convenient way to apply a thin, uniform lubricant coating.
• Reduced assembly friction: Can help reduce the force required for assembly and disassembly of threaded connections and interference fits.
• Aircraft applications: DuPont identifies the product as suitable for airframe and aircraft engine applications.

How to Apply MOLYKOTE G-N Metal Assembly Spray

MOLYKOTE G-N Spray should be applied in a sweeping motion to produce a thin, uniform coating. Avoid excessive application. DuPont recommends clean, dry surfaces for best results, although the product can also be applied to oily surfaces.

No burnishing is required when using the spray. The lubricant's solvent evaporates after application, with DuPont's technical data indicating that the solvent evaporates within approximately 30 minutes.

Allow sufficient time for the solvent to evaporate before placing the component into service, based on the specific application and applicable maintenance procedures.

Aircraft and Aerospace Applications

MOLYKOTE G-N Metal Assembly Spray is particularly relevant to aerospace maintenance because DuPont specifically identifies the product as suitable for airframe and aircraft engine applications.

The lubricant can be used where protection against friction and high-load conditions is required, including assembly, running-in, threaded connections, splines, plain bearings, and other metal components. Its aerosol format is useful when a thin coating needs to be applied without the burnishing associated with some solid lubricant pastes.

For aircraft maintenance, always verify lubricant selection against the applicable aircraft, engine, component, or maintenance-manual requirements before use. Do not substitute a lubricant for a specified product unless the applicable maintenance documentation permits the substitution.

Galling, Seizing, and Fretting Protection

High loads and relative movement between metal surfaces can produce galling, seizing, fretting wear, and excessive friction. MOLYKOTE G-N Metal Assembly Spray is formulated to provide solid-lubricant protection under boundary and high-load conditions.

The molybdenum disulfide-containing formulation provides a low-friction lubricating film that helps reduce surface damage and frictional forces during assembly and running-in. It can also help reduce the force required to disassemble threaded fasteners and other metal connections.

MOLYKOTE G-N Spray vs. MOLYKOTE G-N Paste

MOLYKOTE G-N Metal Assembly Spray and MOLYKOTE G-N Metal Assembly Paste are based on the same general solid-lubricant technology, but they are supplied in different formats.

MOLYKOTE G-N Spray is an aerosol formulation designed to provide a thin, uniform coating without burnishing. It is particularly useful where aerosol application is preferred or where access makes manual application of a paste less convenient.

MOLYKOTE G-N Paste is supplied as a conventional assembly paste and is appropriate where direct application of a heavier paste film is preferred.

Frequently Asked Questions

What is MOLYKOTE G-N Metal Assembly Spray used for?

MOLYKOTE G-N Metal Assembly Spray is used for extreme-pressure lubrication during assembly, running-in, press fitting, threaded connections, and maintenance. It is also used to help protect against galling, seizing, fretting wear, corrosion, and excessive friction.

Does MOLYKOTE G-N Spray contain molybdenum disulfide?

Yes. MOLYKOTE G-N Metal Assembly Spray contains molybdenum disulfide (MoS₂) as a solid lubricant.

Is MOLYKOTE G-N Spray suitable for aircraft?

Yes. DuPont specifically identifies MOLYKOTE G-N Metal Assembly Spray as suitable for airframe and aircraft engine applications. Always verify the applicable aircraft or component maintenance requirements before use.

What is the temperature range of MOLYKOTE G-N Spray?

DuPont's technical data lists an approximate service range of 0°F to 750°F (-18°C to 399°C) for the solid lubricant and 0°F to 250°F (-18°C to 121°C) for the base oil. Application-specific limitations should be evaluated using the current manufacturer documentation.

Does MOLYKOTE G-N Spray need to be burnished?

No. Unlike some solid lubricant pastes, MOLYKOTE G-N Metal Assembly Spray is designed to provide a low-friction coating immediately after application without burnishing.

How should MOLYKOTE G-N Spray be applied?
