A primer layer for fluoropolymer non-stick coating is provided, which comprises a fluoropolymer such as PTFE, a polymer binder such as polyamic acid salt, and inorganic film hardener such as silicate compound, wherein the weight ratio of fluoropolymer to binder is 0.5 to 2.0:1 and the amount of film hardener is 5 to 30 wt % based on the weight of the baked composition. This primer layer adheres to a wide variety of smooth surfaces such as stainless steel and glass, and to the fluoropolymer overcoat on the primer layer, and provides durabilty to the coating.
