ABSTRACT:
A novel process for bonding a fluoropolymer to a metal surface, the process including flowing the fluoropolymer on the metal surface at a temperature at or above the transition temperature of the fluoropolymer and then holding the fluoropolymer at a temperature incrementally above the melting temperature of the fluoropolymer. The holding period allows the chlorine or fluorine in the chloro-fluoro-polymer subunits of the fluoropolymer to react with the metal and thereby securely bond the fluoropolymer to the metal surface.
