Product Description
MOLYKOTE® 3400A Anti-Friction Coating LF is a gray, heat-cured dry-film lubricant for metal-to-metal sliding contacts with slow to moderately fast movement and medium to heavy loads. The solvent-borne organic-binder coating uses molybdenum disulfide as the solid lubricant and is normally applied as a thin, even 10–15 µm film before a typical 30-minute cure at 200°C. It provides a low-friction, adherent coating with documented load-carrying, corrosion, temperature, and fluid-resistance test data. Applications include brake pins, springs and bearing surfaces, body hinges and linkages, locks and switches, ventilation and servo mechanisms, under-hood linkages, sleeve bearings, cams, threaded connections, and fasteners.
Key features
- Heat-cured dry-film lubrication: Organic-binder, solvent-borne anti-friction coating with molybdenum disulfide solid lubricant for loaded metal-to-metal sliding contacts.
- Controlled film and cure: Recommended average coating thickness of 10–15 µm with typical curing for 30 minutes at 200°C.
- Rotating and oscillating endurance: ASTM D2714 results exceed 48,000 revolutions to μ = 0.1 and 50,000 oscillations to μ = 0.08 on phosphated surfaces under the stated loads and speeds.
- Falex load performance: ASTM D2625 results exceed 16,000 N pressure resistance and 500 minutes average endurance life on phosphated surfaces.
- Corrosion and fluid resistance: More than 500 hours without red rust for spray/dip application on phosphated surfaces, with no adhesion loss in SAE AS 5272 Type II fluid-resistance testing.
Applications / Suitable for
- Brake pins, springs, and bearing surfaces
- Body hinges, linkages, locks, switches, and ventilation controls
- Under-hood linkages exposed to dust, moisture, fuels, oils, and other contaminants
- Hinge pins, sleeve bearings, cams, servo mechanisms, and instrument bearings
- Threaded connections and fasteners

Additional Information
MOLYKOTE® 3400A Anti-Friction Coating LF
A gray, solvent-borne anti-friction coating for metal-to-metal sliding contacts with slow to moderately fast movement and medium to heavy loads. Its organic-binder system uses molybdenum disulfide solid lubricant and cures into a thin dry film with documented load, endurance, corrosion, temperature, adhesion, and fluid-resistance test results.
MOLYKOTE® 3400A LF is supplied as a gray, solvent-borne liquid coating that forms a heat-cured dry lubricant film.
As-supplied coating properties
Typical values are not specification limits. Product identity and technology reflect the current supplier product page; density and color are supported by the product technical data.
Prepare a clean surface, apply a thin film, and heat cure
Coating performance depends on complete degreasing, thorough mixing, even application, and a controlled cure. Select spraying, dipping, painting, or centrifuging according to part geometry and production method.
Application sequence
Store at or below 20°C (68°F) in the original unopened container. Usable life is 24 months from the date of production under these conditions. Review the current safety data sheet and container label before handling, and follow the site controls required for solvent-containing coatings.

Typical laboratory results are not guaranteed specifications. Values apply to the stated tests and phosphated specimens where identified; they must not be converted into universal component life, equipment load, or corrosion-free service claims.
Metal-on-metal applications
The coating is used on sliding metal contacts where part geometry, movement, load, environment, film thickness, cure, and surface preparation can be controlled. Validate the coating on the actual substrate, pretreatment, dimensions, and duty cycle.
