A process for forming a release surface on a substrate includes applying a primer powder on the substrate to form a primer layer, applying an overcoat powder on the primer layer to form an overcoat layer, and baking the substrate after applying both the primer powder and the overcoat powder. The primer powder includes a tetrafluoroethylene/perfluoroolefin copolymer and a non-melt processible binder. The overcoat powder includes a tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer.
