abstract |
The present invention is characterized in that the aromatic polymer is in the form of a powder having a d90 of 20 μm or less, and the aqueous coating composition further comprises a polar aprotic solvent in a content of more than 0 wt% and not more than 25 wt%. And an aqueous amine-free coating composition comprising at least one aromatic polymer. The invention also relates to an aqueous, amine-free, non-stick coating composition comprising such an aqueous composition for coating, and a respective method for making it. The invention further relates to a method for producing an item on one side of a metal substrate from at least one coating composition or one non-stick coating composition according to the invention. |
