Product Description
MOLYKOTE® D-708 Anti-Friction Coating is a black, heat-curing dry-film lubricant for low- to medium-load metal-to-metal and metal-to-plastic interfaces. The PTFE-filled organic binder and solvent system can be spray- or dip-applied after cleaning and degreasing, at a recommended 5–15 µm film thickness, then cured for 60 minutes at 180°C or 20 minutes at 200°C. The cured film operates from -60°C to 240°C and provides a glossy black surface. Typical performance includes a 0.11 coefficient of friction in an internal 50-cycle polymer test, 1,220 N ASTM D2625 Falex pressure resistance, and more than 700 hours of salt-spray resistance for an 11 µm coating over zinc phosphate. Documented uses include safety-belt components, transmission parts, and door locks.
Key features
- Controlled thin-film process: Apply by spray or dip coating at a recommended 5–15 µm thickness, with documented cure options of 60 minutes at 180°C or 20 minutes at 200°C.
- Broad cured-film temperature range: Documented operating range of -60°C to 240°C.
- Condition-specific friction data: Typical coefficient of friction of 0.11 in an internal polymer test using 50 cycles, a 250 g load, and a 20 mm stroke.
- Corrosion-test evidence: More than 700 hours in an ISO R 1456 salt-spray test for an 11 µm coating applied over zinc phosphate.
- Glossy black cured finish: Combines lubrication and corrosion-protection functions with a high-quality visible surface finish.
Applications / Suitable for
- Safety-belt components and related automotive mechanisms
- Transmission and actuation parts with low- to medium-load sliding contacts
- Door locks, latches, and closure mechanisms using metal or plastic contact pairs

Additional Information
MOLYKOTE® D-708 Anti-Friction Coating
A solvent-borne anti-friction coating for low- to medium-load metal-to-metal and metal-to-plastic interfaces. The PTFE solid-lubricant and organic-binder system supports spray or dip application of a controlled thin film, followed by heat cure to create a glossy black lubricating and corrosion-protective surface for automotive and mechanical components.
MOLYKOTE® D-708 is supplied as a black solvent-borne liquid that forms a glossy, heat-cured anti-friction film.
As-supplied coating properties
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Physical form | Liquid | — | As supplied |
| Color | Black | — | As supplied |
| Viscosity | 7–10 | s | ASTM D4212; Zahn No. 3 cup |
| Density | 0.95 | g/mL | ASTM D1475 at 25°C |
| Flash point | 0 | °C | ASTM D56 |
Typical values are not specification limits. The flash-point value describes the as-supplied solvent-borne coating and is not a cured-film operating limit.
Prepare, coat, and heat cure a controlled thin film
Coating performance depends on surface cleanliness, pretreatment, uniform film build, and a verified cure. Establish process controls using representative components, equipment, and production conditions before fixing the application specification.
Application sequence and process controls
Shelf life is 6 months in the original sealed container when stored above -18°C (0°F). The as-supplied coating is highly flammable and has a documented closed-cup flash point of approximately 0°C; review the current safety data and use the required ventilation, ignition-control, grounding, bonding, and personal-protection measures.
Cured-film performance and corrosion protection
The cured coating combines friction control, load support, corrosion protection, and a glossy black finish. Interpret each result within its stated film thickness, substrate preparation, test geometry, load, and procedure rather than as a universal assembly limit.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Cured-film appearance | Glossy black | — | Visual characteristic of the applied and cured coating |
| Operating-temperature range | -60 to 240 | °C | Supplier guidance for the cured film |
| Coefficient of friction | 0.11 | — | Internal polymer test; 50 cycles, 250 g, 20 mm stroke |
| Falex pressure resistance | 1,220 | N | ASTM D2625 |
| Salt-spray corrosion protection | >700 | h | ISO R 1456; 11 µm coating over zinc phosphate |
| Theoretical coverage at 10 µm | 60 | ft²/lb | Excludes application-process losses |
Typical laboratory results are not guaranteed specifications. The corrosion result applies to the stated 11 µm coating over zinc phosphate, and the coefficient of friction applies only to the identified internal test conditions.
Automotive and mechanical friction applications
MOLYKOTE® D-708 is intended for low- to medium-load metal-to-metal and metal-to-plastic pairings that can be integrated into a spray- or dip-coating and oven-curing process. Confirm substrate, pretreatment, film thickness, friction target, corrosion requirement, and cure capability on the production assembly.
