Purpose:This specification establishes the engineering requirements for producing thick coating of polytetrafluoroethylene resin on parts and the properties of such coatings. Application: Primarily to provide dry lubrication@ high heat stability@ and corrosion protection on parts which operate at not higher than 275 oC (525 oF) for limited periods or not higher than 245 oC (475 oF) 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
