GENERAL DESCRIPTION
Sandstrom 28A Solid Film Lubricant is a lacquer-like
coating containing molybdenum disulfide and corrosion
inhibiting pigments. This Air Drying material prevents
corrosion, galling, seizing and fretting. It is a low-friction
coating which exhibits long wear life when operated at
-320oF to 500oF under loads exceeding 100,000 psi.
Sandstrom 28A should be applied where baking with
the longer wearing, heat cured #099, Sandstrom 9A or
LC-300 is not desirable.
Excellent Corrosion Protection without the use of toxic
heavy metals and the use of non-HAP solvents are its
outstanding characteristics.
Once Sandstrom 28A has been applied to a properly
prepared surface and allowed to cure, it is virtually unaffected
by atmospheric and fretting corrosion, solvents, acids, oils
and degreasers. Sandstrom 28A can be applied to all
metallic and non-metallic surfaces by spray application.
Complete application instructions are on page two of this
Technical Information Guide.

TECHNICAL INFORMATION GUIDE
SANDSTROM 28A CONTAINS
NO GRAPHITE, TOXIC HEAVY METALS,
OR HAP SOLVENTS
RECOMMENDED USAGE
Sandstrom 28A is an excellent in-plant or field solution to
the problem of lubricating parts:
? Where application of a baked-on lubricant is not possible
? Which may 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
? Where "clean operation" is desired
(Sandstrom 28A 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 is
needed
? Where fretting and galling is a problem (such as splines, universal
joints and keyed bearings)
? Where easy release is desired (such as threads of all kinds)
