MIL-PRF-46010H
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is
not mandatory.)
6.1 Intended use. The solid film lubricant covered by this specification is intended for
use on aluminum, aluminum alloys, copper, copper alloys, steel, stainless steel, titanium,
chromium, and nickel bearing surfaces (see appendix for application instructions). It is useful
under the following conditions:
a. To touch up worn surfaces originally coated with lubricant conforming to
MIL-L-46010 or MIL-PRF-46010.
b. For sliding motion applications such as plain and spherical bearings, 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 temperatures 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.
6.1.1 Use limitations. 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 for l hour.
b. In operations consisting of rotary motion above 100 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.
6.1.2 Corrosion protection life. This lubricant, when under static conditions, can be
expected to provide corrosion protection for five years in indoor storage and approximately two
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 four years.
