This specification establishes the engineering requirements for producing thick coatings of polytetrafluoroethylene (PTFE) resin on parts and the properties of such coatings. Primarily to provide dry lubrication, high heat stability, and corrosion protection on parts which operate at not higher than 527 degrees F (275 degrees C) for limited periods or not higher than 473 degrees F (245 degrees C) for extended periods. This coating is usually smoother than that of AMS 2515. This coating may also be used as a release film for molds.
