Dry Film Lubricants, also called solid film lubricants, are high performance coatings made up of very fine particles of molybdenum disulfide lubricating agents blended with binders and other special additives. Once cured, these lubricating agents bond to the part surface as a solid film which reduces galling, seizing and fretting and protects against corrosion. Through the combination of these properties, dry film lubricants greatly improve the wear life of coated parts.

Dry film/solid film lubricants allow for operating pressures above the load-bearing capacity of normal greases and oils. They are also less prone to collecting soil particulates than greases and oils. In some applications, the coating is self-burnishing, leading to improved, rather than decreased, performance over time. Some blends of dry film/solid film lubricants are also temperature and chemical resistant allowing for their use in harsh environments such as jet engines where exposure to aviation fuel and extreme temperatures are the norm.
