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 that exhibits long wear life when operated at -320°F to +300°F under loads exceeding 100,000 psi. Once 28A has been applied to a properly prepared surface and allowed to cure, it is virtually unaffected by atmospheric and fretting corrosion, acids, oils and degreasers. Sandstrom 28A can be applied to all metallic and non-metallic surfaces by spray application.
