Slickote 3-8                        

Solid Film Lubricant

Product Description

Heat cured, bonded Solid Film Lubricant to provide low friction, high load lubrication under a wide temperature range.

Slickote 3-8 contains molybdenum disulfide, graphite, binders and solvents (refer to msds). This material does not contain arsenic, antimony or lead compounds.

Intended Use

To reduce wear and prevent galling, corrosion and seizure of metals.

Where conventional lubricants are difficult to apply or retain, or where other lubricants may be easily contaminated with dirt and dust.

For sliding motion applications such as plain and spherical bearings, flap tracks, hinges, threads and cam surfaces.

Where temperature ranges are from -100 deg F to +500 degF

When mechanisms are operated at infrequent intervals or are lubricated for life.

Where long term corrosion protection is required under static conditions.

Where solvent resistance is required

Where extremely heavy loaded lubrication is required including initial start up of heavy loaded mechanismsdesigned for fluid lubrication.

Application Procedure

Metal Preparation: All surfaces must be thoroughly cleaned, degreased, free of rust, oxides or other surface impurities. 

Recommended pretreatments:

Pretreat iaw blue print requirements.

For best adhesion results, aluminum oxide grit blast (120 to 400 mesh) prior to coating.

Apply Slickote 3-8 within 72 Hrs of pretreatment

Ferrous Alloy: Alum oxide blast, manganese phosphate (omit chromic acid rinse) -BAC 5810

CRES: Alum oxide blast, passivate -BAC 5748, AMS-QQ-P-35

Aluminum: Anodize and seal as specified

Titanium: Alum oxide blast, fluoride phosphate -BAC 5748

Cad/ Zinc Plate: Light zinc phosphate BAC 5810

Refer to Boeing specification, BAC 5811 for complete process details


Mix material well, in mechanical paint shaker.

Concentrate only: Reduce with Slickote 3-8 Reducer, 2 parts reducer to 1 part concentrate by vol.

Use conventional spray gun (unless HVLP required by local air quality authority) or dip method.

Maintain continuos agitation to avoid settling. Spray 6 to 8 inches from part.

Apply coating thickness; 0.2 to 0.5 mil General Rule: 2 passes of spray gun will provide apx 0.1 mil thickness (use: 4 to 10 passes).

Verify thickness prior to cure (Note: thickness will shrink apx 15% after cure).

Cure: 30 min air dry and:

375 degF for 60 minutes (ferrous, CRES, PH stainless, titanium, copper, cad, chrome, plating) or;

300 degF 60 minutes (aluminum, carburized steels, 440 stainless)

Refer to cure tables in BAC 5811

Note: Remove masking tape, solvent clean prior to cure to avoid tape glue residue (brownish stains).

Processing Notes

Comp Air: Oil/ Moisture Free (test iaw BSS 7217- record daily)

Ovens: Certified to +/-15 degF, uniformity survey.

Humidity: Apply only when relative humidity < 70% (record daily, each 4 hours)

Thermal Profile: Cure times start when parts reach cure temperature (not when placed in oven).

Use thermocouple to monitor time to temp (varies with part, oven load etc). General rule: Allow 8 to10 minutes for parts to reach cure temp.

Cure History: Use oven charts, logs to record cure time in/ out. Maintain traceability to work order.

Traceability: Record material batch # and expiration date on the work order or log.

Rework: Verify thickness prior to cure (thickness will shrink apx 15% after cure). When oversize, remove with solvent and reapply.

Once cured, do not apply additional coat to build up thickness or repair defects.

Coating may be reworked one time only (except aluminum- refer to BAC 5811). Best method for strip - walnut shell blast (BAC5748). Alternative, chemical strip (BAC5725)

Lot Testing: Appearance - smooth, uniform, no grit, runs, cracks, blisters, foreign matter or other defects.

Thickness - Eddy current method only (ASTM E376, part or panel). Micrometer is not permitted for final inspection. Requirements: 0.2 to 0.5 mil.

Adhesion tape test (BSS7225 ty1)
