Metallic substrates with fluorocarbon coverings; and method of manufacture

Abstract From the Canadian patent

Abstract of the Disclosure Surfaces of thermally conductive substrates are covered with thermoplastic polymers, particularly certain fluorocarbon polymers by bonding said polymeric materials directly to surfaces of said substrates. Adhesives etchants, or the, like are not used as bonding elements. The process involves treating the surfaces to make them wettable by water and then cleaning the surfaces, if necessary, followed by heating the substrate to a temperature at which the polymer melts gels, or softens (herein called the softening point) then placing, the polymeric material into contact with the prepared surfaces and applying pressure on the polymeric material to force it into fusing …
