Also called Salt Spray Testing, is described in ASTM B117. The test provides a controlled corrosive environment which is used to generate resistance information for metals and coated metals exposed in the test chamber.
Coatings meeting this specification will provide excellent lubricity and corrosion protection. This is one of the more common heat cured Dry Film Lubricant specifications that is used in the field.
A DuPont trade name for Polytetrafluoroethylene. This synthetic resin provides excellent lubricity under light loads.
Dry Film Lubricants
Dry Film Lubricants (DFL), also known as Solid Film Lubricants (SFL), provide lubrication in areas where wet lubricants are not practical. Dry Films are typically made up of formulas containing molybdenum disulfide, graphite, or Teflon™. Some Dry Films also provide excellent corrosion protection.
