Definitions
- the present invention generally relates to articles having a non-stick coating having improved adhesion properties to the carrier.
- the present invention also relates to a method of manufacturing such a culinary article.
- the field in question is primarily that of culinary articles such as stoves or saucepans, but the present invention may also relate to any other type of surface provided with a non-stick coating such as the soleplate of an iron.
- a relatively thick coating typically having a total thickness of between 10 and 50 ⁇
- fluorocarbon resin is used as a release coating on the inside of a culinary article.

- the release coating has a thickness equal to or greater than 400 nm, and preferably between 2 and 50 ⁇ .
- the fact that the interface layer is chemically activated makes it possible to anchor a thick non-stick coating on the support. If the interface layer were not chemically activated, for example simply roughened and cleaned by plasma treatment as taught by international applications WO 03/035154 and WO 2008/146025, it would not be possible to deposit resin layers. fluorocarbon also thick.
- the fluorocarbon resin may be chosen from polytetrafluoroethylene (PTFE), the copolymer of tetrafluoroethylene and perfluoropropylvinylether (PFA), and the copolymer of tetrafluoroethylene and hexafluoropropylene (FEP), the copolymers comprising at least 50 mol% of tetrafluoroethylene , and their mixtures.

- the interface layer of the support is a thin layer formed by plasma polymerization (plasma treatment with precursor), preferably a layer obtained from metal alkoxide, and better from alkoxysilane, siloxane or silazane.
- the interface layer of the support is obtained by chemical grafting by plasma treatment (without precursor) under atmospheric pressure or under a partial vacuum between 0.133 Pa (10 -3 mmHg) and atmospheric pressure, and then plasma polymerization ( precursor treatment), which is preferably a layer obtained from metal alkoxide, and preferably from alkoxysilane, siloxane or silazane.
- plasma treatment without precursor
- plasma polymerization precursor treatment
- the binder for adhering the non-stick coating according to the invention may advantageously be chosen from polyamide imides (PAI), polyether imides (PEI), polyamides (PI) and polyetherketones (PEK), polyetheretherketones (PEEK), polyethersulfones (PES) and polyphenylene sulfides (PPS).

- Such a treatment also makes it possible to modify the surface states and to reach, in particular, surface tensions of the order of 72 ⁇ m / m on aluminum supports, which improves the wettability of the substrate.
- this treatment creates an oxidation layer that is favorable to adhesion. It is then possible, thanks to this pretreatment of the layer formed by plasma polymerization, to use a non-stick coating essentially free of bonding binder (for example comprising only one or more topcoats).
- the present invention also relates to a method of manufacturing an article according to the invention, comprising the following steps:
- ⁇ preparing at least one composition based on at least one fluorocarbon resin in particulate form, said fluorocarbon resin being alone or in admixture with a thermostable bonding binder and resistant to at least 200 ° C;
- said method being characterized in that it further comprises, before the formation of the non-stick coating on one of the faces of the support, a step of chemical activation by plasma treatment of this face, so as to create an interface layer chemically activated on this face.
- the composition based on fluorocarbon resin (s) is applied in a layer having a total dry thickness of at least 400 nm, and preferably between 2 and 50 ⁇ .
- the application of such a layer can be done conventionally (spraying, screen printing, pistolsammlung, roll, tempered, curtain).
- the support, the fluorocarbon resin and the thermostable bonding binder are as defined above.
- the method according to the invention comprises, prior to the formation of the non-stick coating, a step of producing a hard base on said face of the support.
- the interface layer is a layer formed by plasma polymerization (with precursor).
- a precursor in liquid or gaseous form is added at the outlet of the plasma torch, so that the molecules are decomposed into high energy fragments whose pieces react with each other on the substrate and which form a more or less strongly crosslinked layer.
- the substrate which is at least partially metallic
- the substrate receives a deposit of a coating of a thickness between a few nanometers up to a few hundred nanometers which has been formed by the atmospheric reactive plasma. Ultra-thin layers of coatings are thus deposited by plasma.
- the interface layer is a layer formed by a plasma polymerization treatment (according to the second embodiment of the process of the invention), which follows a plasma treatment under atmospheric pressure or under a partial vacuum between ⁇ 3 mm Hg and atmospheric pressure (without precursor).
- a plasma treatment consists in exposing a surface to a plasma which consists of either inert gases (noble gases) or molecules containing atoms which are not capable of forming chains (for example N 2 , O 2 , NH 3) .
- Plasma produces high energy particles such as electrons, high energy radiation, but also excited ions and particles, which always leads to a surface modification: bonds break and active sites on the material are created. .
- active sites can react with each other and thus cause additional crosslinking in the surface area. They remain partly in the surface of high crosslinking and thus form an activated surface capable of spontaneous reactions p. ex. with atmospheric oxygen. Gases that are not noble gases such as N 2 , O 2 or NH 3 can additionally be introduced on the surface of the atoms they comprise. Characteristics such as the adhesive power, the adhesion of the varnish, the wettability and the surface energy are thus significantly improved (compared to a simple polymerization). Activation and cleaning are two phenomena that usually occur at the same time.

- n being an integer corresponding to the maximum valence of the metals M lr M 2 or M 3
