The present invention relates to an aqueous composition for coatings, which is free of amines and comprises at least one aromatic polymer, characterized in that the aromatic polymer exhibits a value of less than or equal to In the form of a powder with a d90 of 20 μm, and the aqueous composition used for the coating further comprises a polar aprotic solvent whose weight content is greater than 0% and less than or equal to 25%. The present invention also relates to an amine-free aqueous composition for anti-stick coatings comprising such an aqueous composition for coatings, and to their respective methods of manufacture. The invention also relates to a method for producing a device on one of the sides of a metal substrate, said device having at least one layer of the composition for the coating or at least one layer of the anti-stick coating according to the invention of the composite. |
