LC-300 SOLID FILM LUBRICANT
HEAT CURING
SERIES V765 LEAD FREE
MEETS SAE SPEC AS5272C TYPE I (FORMERLY MIL-L-46010 TYPE I)
DESCRIPTION
Sandstrom LC-300 Dry Film Lubricant is a lead free lacquer-like
coating containing molybdenum disulfide and corrosion-inhibiting
pigments. This Heat Curing material prevents corrosion, galling,
seizing, and fretting. It is a low-friction coating which exhibits long
wear life when operated at -320oF to +400oF under loads exceeding
100,000 psi.
LC-300 should be applied in place of Sandstrom 9A where
maximum wear life and corrosion protection from a dry film lubricant
are required on metals which may be adversely affected by
9A's 1 hour @ 400oF bake cycle.
Once Sandstrom LC-300 has been heat cured, it is virtually
unaffected by atmospheric and fretting corrosion, solvents, acids,
oils, and degreasers, and is not resoftened again at elevated
temperatures.
LC-300 may be applied to a wide variety of surfaces by spraying or
dipping. Complete application instructions are on the reverse of
this sheet.
OUTSTANDING FEATURES/BENEFITS
Excellent Corrosion Protection, Chemical Resistance, and Long
Wear Life are its outstanding characteristics.
SANDSTROM LC-300 CONTAINS NO LEAD or GRAPHITE
TYPICAL USES
Sandstrom LC-300 is an excellent solution to the problem of
lubricating parts:
• Where "clean operation" is desired (LC-300 will not collect dirt and
debris as do grease and oils)
• Where parts may be subjected to frequent disassembly
• Where a protective coating and sacrificial break-in lubricant are
needed
• Where fretting and galling is a problem (such as splines, universal
joints, and keyed bearings)
• Where easy release is desired (such as acme nuts and screws
and PVC molds)
• Where metallurgical properties are adversely affected by baking
at temperatures higher than 300oF
• That will be operated in corrosive atmospheres
• That may be stored for long periods
• Which are seldom lubricated once they leave the factory and
where permanent lubrication is desired
• Where operating pressures exceed the load-bearing capacities of
ordinary oils and greases

GENERAL
Sandstrom LC-300 is a paint-like material consisting of lubricative
pigments dispersed in a thermosetting resin system thinned with appropriate
solvents. For maximum service, the APPLICATION INSTRUCTIONS
MUST BE FOLLOWED CLOSELY. The lubricant is flammable and the safety
precautions usually followed when using flammable materials should be
observed.
FILM THICKNESS AND ENGINEERING TOLERANCES
As supplied, Sandstrom LC-300 will yield a film thickness of about .0005
inches per dip coat. Usually engineering tolerances will permit necessary
minimum film buildup of .0002 to .0003 inches without interference. If
excess buildup does occur and a force fit is necessary, burnishing lightly
will assist in mating the parts. The remaining excess will be worn away in
the first few cycles of operation. Whenever possible, the proper tolerances
