Sandstrom LC-300 Flat Dark Gray AS5272 Type I & II Spec Heat Cure Solid Film Lubricant
Sandstrom LC-300 is a lead free lacquer-like dry film lubricant coating containing molybdenum disulfide and corrosion-inhibiting pigments. This Heat Curing material prevents corrosion, galling, seizing and fretting. It is a low-friction coating that exhibits long wear life when operated at -320°F to +400°F under loads exceeding 100,000 psi.
LC-300 may be applied by brush, dip, dip spin or spray method. After it is heat cured, LC-300 is virtually unaffected by atmospheric and fretting corrosion, solvents, acids, oils and degreasers and is not re-softened at elevated temperatures.
Dependent on the bake schedule, LC-300 is qualified to both AS5272 Type I and Type II. The wet coating itself is the same, allowing inventory of one product to meet two specifications.
