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 &#x3bc;m 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.

Aqueous semi-finished and primary non-stick coating compositions comprising aromatic polymers

Provided are non-stick coating hybrid primer compositions based on polyimide resin and/or polyamide-imide resin. Also provided are processes for preparing such compositions. Finally, non-stick coatings incorporating such compositions and a process for manufacturing articles comprising such non-stick coatings are provided.

Non-stick coating primer compositions and processes for the preparation thereof

Provided is an aqueous amine-free coating composition including at least one heterocyclic polymer, wherein the heterocyclic polymer is in the form of powder having a dless than or equal to 20 &#x3bc;m. 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 coating composition or one layer of non-stick coating composition according to the invention.

Aqueous semi-finished and primary non-stick coating compositions comprising heterocyclic polymers

Provided is a primer composition for a non-stick coating which includes a polyamide-amic acid having an acid value of 50 to 200 mg KOH/g, a Lewis base, water and at least 5 wt % of a polar aprotic solvent relative to the total weight of said composition. According to the invention, the weight ratio of PAI/polar aprotic solvent in said composition is at least 1.5. Also provided is a method for preparing such a composition, and a method for manufacturing an item comprising a metal substrate to which such a composition is applied.

Primer compositions for non-stick coatings and method for manufacturing same

Provided is a metal-oxide nanofiller including at least two graft chains, at least one of the chains being hydrophilic and the other being a hydrophobic chain compatible with fluorinated polymers. The hydrophobic chain is an oligomer, the weight-average molar mass Mw of which is between 300 and 20,000 g/mol. Also provided is a non-stick coating comprising such a filler, as well as to a culinary article provided with such a coating.
