Solid film lubricants are paint-like coatings of very fine particles of lubricating pigment blended with a binder and other additives.
The lubricant is applied to a substrate by spray, dip or brush methods and, once cured, creates a solid film which repels water, reduces friction and increases the wear life of the substrate to which it has been applied.
[1] Certain film lubricants also offer additional properties such as corrosion inhibition.
Solid film lubricants are used in the automotive, transportation and aerospace industries.
2 commonly used ones are graphite and molybdenum disulfide.
