The lubricant covered by this specification is military unique due to the requirement that its performance should not be degraded as a result of exposure to the military unique fluids specified in table I. The lubricant is intended for use on aluminum and aluminum alloys, copper and copper alloys, steel, stainless steel, titanium, and chromium and nickel bearing surfaces (see appendix for application instructions), and is useful under the following conditions:

a. To touch up worn surfaces originally coated with lubricant conforming to MIL-L-8937, MIL-L-46010 or MIL-PRF-46010.

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

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

d. Where temperature may range from −68°C to +204°C (although intermittent exposure to +260°C is acceptable)

e. If mechanisms are operated at infrequent intervals or are lubricated for life.

f. Where long-term corrosion protection is required under static conditions.

g. Where a solvent-resistant coating is required.

h. Where a lubricant requires extremely heavy load ability in the initial start-up of heavy loaded mechanisms designed for fluid lubrication.

This lubricant should not be used under the following conditions:

a. On materials which will be adversely affected by the curing temperatures of 204 ± 15°C.

b. In operations consisting of rotary motion above 100 revolutions per minute (rpm) under heavy loads where the possibility of conventional fluid lubricant contamination exists. The cured lubricant film is highly resistant to conventional fluid lubricants, but the high fluid pressures developed in heavily loaded sleeve type bearings drastically reduces the wear life provided by the solid lubricant film.

c. On bearings containing rolling elements.

d. Where there is potential contact with liquid oxygen.

e. If more than 12 months have elapsed since the date of manufacture.

This lubricant, when under static conditions, can be expected to provide corrosion protection for 5 years in indoor storage and approximately 2 years protection in outdoor storage when lubricant is applied over phosphated steel to a thickness of 0.013 mm. Where maximum corrosion protection on steel is desired, the lubricant should be applied over phosphated steel to a thickness of 0.025 mm. The heavier coating can be expected to provide outdoor corrosion protection for approximately 4 years.
