Described herein is multilayer article and methods of making thereof, wherein the multilayer article comprises: (a) metal substrate; (b) a first fluoropolymer layer having a thickness no more than 10 micrometers, wherein the first fluoropolymer layer consists essentially of a fluoropolymer comprising reactive groups, wherein when the fluoropolymer is a melt-processible fluoropolymer it comprises at least 30 reactive groups per 1,000,000 carbon atoms and when the fluoropolymer is a non-melt processible fluoropolymer it comprises more than 5 reactive groups per 1,000,000 carbon atoms; and (c) a second fluoropolymer layer having a thickness of about 10 to 1000 micrometers, wherein the first fluoropolymer layer is in contact with both the metal substrate and the second fluoropolymer layer.
