Dry Film lubrication

Dry Film Lubricants, are high performance coatings made up of very fine particles of molybdenum disulphide, lubricating agents blended with binders and other additives. Once cured, it bonds to a surface as a solid film which reduces galling, seizing and fretting. Dry film lubricants improve the wear life of coated parts.

Dry film/solid film lubricants can operate at pressures above the load-bearing capacity of normal greases. They also collect less soil particulates. In some applications, the coating is self-burnishing this can lead to improved, performance over time. Some blends of dry film/solid film lubricants are also temperature and chemical resistant allowing for their use in harsh environments.
