Abstract
A method for applying a release coating to a metal support includes the following steps: i. depositing on the metal support one or more continuous layers of a tie sublayer comprising one or more polymers selected from the group consisting of polyaryletherketones (PAEK), polyethyleneimines (PEI), polyimides (PI), polyamide imides (PAI) and polybenzymidazoles (PBI) in an amount of 20% to 95% by weight of the total weight of said sublayer, characterized in that it comprises only a single sintering step at T° C.>400° C., and that of the total, after the deposition of the various layers.

A method for applying a non-stick coating to a metal support comprising the following steps:
- i. Depositing on the metal support one or more continuous layers of a tie sublayer comprising one or more polymers selected from the group consisting of polyaryletherketones (PAEK), polyethyleneimines (PEI), polyimides (PI), polyamide imides (PAI) and polybenzymidazole (PBI) in an amount of 20 to 95% by weight of the total weight of said sublayer,
- wherein said method comprises, in overall, only a single sintering step at T° C.>400° C., after the deposition of the various layers.
A method for manufacturing a culinary article comprising the following steps:
- i. a step of providing a metal support, comprising two opposite faces,
- ii. a step of shaping said support to give it the shape of a cap, which comprises a bottom and a side wall rising from the bottom, and thus define a concave internal face adapted to receive food and a convex external face, said step ii) being carried out either before step iii) of producing the tie sublayer, or after step iv) of producing the non-stick coating,
- iii. Depositing, on the internal face or on the bottom of the support, one or more continuous layers of the tie sublayer as defined in claim 1,
- iv. Optionally depositing one or more layers of a non-stick coating based on fluorocarbon resins, on said tie sublayer deposited in step (iii),
- wherein the method comprises in overall only a single sintering step (v) at T° C.>400° C., after the deposition of the various layers.
