  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
should be designed into the part.
COVERAGE
One gallon of this material will cover 625 sq. ft. with a dry film thickness
of .0005 inches. Coverage depends upon methods of application and other
variables such as overspray and type of surface to be coated. Above
coverage rates are based on 100% efficiency.
SURFACE PREPARATION
The following surface preparations are recommended for the individual metals
listed in the Application Appendix of the military specification to develop
maximum adhesion, wear life, and corrosion protection. Please contact
Sandstrom Products Company for substitute surface preparations if recommended
steps cannot be followed.
Application on steel. Preclean the steel surface with aliphatic naphtha or
any other EPA compliant cleaner that sufficiently cleans surfaces to pass
ASTM F22. Sandblast the surfaces with 180-220 grit aluminum oxide. Phosphate
IAW MIL-DTL-16232 (weight should be 11-22 g/m2), type M, class 3 or
type Z, class 3.
Application on stainless steels. Preclean the steel surface with
aliphatic naphtha or any other EPA compliant cleaner that sufficiently
cleans surfaces to pass ASTM F22. Sandblast the surfaces with 120 grit
aluminum oxide. Passivate the surfaces with ASTM A967, types nitric 1,
nitric 2 or nitric 3, as applicable.
Application on aluminum and aluminum alloys. Preclean the
aluminum surface with aliphatic naphtha or any other EPA compliant
cleaner that sufficiently cleans surfaces to pass ASTM F22. Sulfuric acid
anodize IAW MIL-A-8625 and seal the surface.
Application on titanium and titanium alloys. Degrease the surfaces
to be coated with aliphatic naphtha or any other EPA compliant cleaner that
sufficiently cleans surfaces to pass ASTM F22. Sandblast the surface
with 180-220 grit aluminum oxide and alkaline anodize.
Application on copper and copper alloys. Preclean the copper
surface with aliphatic naphtha or any other EPA compliant cleaner that
sufficiently cleans surfaces to pass ASTM F22. Sandblast the surfaces
with 180-220 grit aluminum oxide. Form a black oxide finish on the
surfaces.
importANT! DO NOT TOUCH CLEAN SURFACE WITH
FINGERS - OIL FROM THE HANDS WILL INTERFERE WITH
PROPER COATING ADHESION. Whenever possible, treat both
contact surfaces (i.e., the shaft and the bearing).

NOTICE
Before using this product, read all warnings and safety information
printed on the label, the Material Safety Data Sheet, and
the Technical Information Guide.
STIRRING
importANT! THIS LUBRICANT ConTAINS HEAVY PIGMENTS
WHICH SETTLE RAPIDLY. THEREFORE, IT SHOULD BE
STIRRED THOROUGHLY BEFORE USE AND CONTINUOUSLY
DURING APPLICATION.
THINNING
For spraying - Sandstrom LC-300 may be thinned using D169
Thinner. The suggested starting point is 2 parts LC-300 to 1
part thinner.
For dipping - IF NECESSARY, use a slow drying thinner such
as PM acetate in such proportions as to provide proper runoff
characteristics. The suggested starting point is 4 parts of LC-
300 to 1 part thinner.
APPLICATION
Sandstrom LC-300 should be sprayed or dipped to the desired
film thickness (usually .0003 to .0007 inches). Allow the
surface to dry at least 30 minutes at 77oF + 5oF and at less than
70% relative humidity before baking. Lower temperatures and/
or higher humidity may require longer dry time to prevent
defects.
BAKING
BAKING AT 300oF FOR ONE (1) HOUR in a forced draft oven
WILL YIELD OPTIMUM CORROSION PROTECTION AND
WEAR LIFE.
importANT! The hour begins when the part has reached
300oF NOT when it is placed in the oven. In cases of very thick
metals, an extra hour may be required to bring the part up to
the proper temperature. Thermocouples may be used to
determine the true temperature of the metal.
To test for complete cure, light rubbing with MEK on a rag will
not remove coating to bare metal.
CLEANUP
Use the same solvents for cleaning tools as are recommended
for thinning.
REMOVAL OF SANDSTROM LC-300
In the event it is necessary to remove Sandstrom LC-300,
physical removal is best (such as grit blasting, sanding, or
grinding). Also, selected epoxy cold strippers will remove LC-
300.
*Strict compliance to the instructions given in Surface Preparation,
Thinning, Application, and Baking is very essential for
obtaining optimum results.
WARNINGS: Constant stirring is imperative for best results.
DANGER! Flammable - keep away from heat, sparks, and
open flame. USE WITH ADEQUATE VENTILATION. Avoid prolonged
breathing of vapor or spray mist. If swallowed, DO
NOT INDUCE VOMITING. CALL PHYSICIAN IMMEDIATELY!
Contains Toluene and Phenolic and Epoxy Resins.
