Abstract

Provided is an aqueous amine-free coating composition including at least one aromatic polymer, wherein the aromatic polymer is in the form of powder having a dless than or equal to 20 μm and in that the aqueous coating composition further includes polar aprotic solvent at a content greater than 0% by weight and less than or equal to 25% by weight. Also provided is an aqueous amine-free non-stick coating composition including such an aqueous composition for a coating, and the respective methods for producing same. Further provided is a method for producing an item on one of the faces of a metal substrate, from at least one layer of the coating composition or one layer of the non-stick coating composition.
