  • the present invention relates generally to articles comprising a non-stick coating having improved properties of adhesion to the support.
  • the present invention also relates to a method of manufacturing such a cookware.

  • a relatively thick coating typically having a total thickness comprised between 10 and 50 ⁇ m
  • fluorocarbon resin for example PTFE
  • Such coatings are known not only for their non-stick properties, but also for their resistance to chemical or thermal attack.
  • such coatings have limited adhesion to metal supports, especially aluminum, stainless steel or cast iron supports.
  • a bonding primer comprising a bonding binder such as PAI
  • chemical surface treatments for example of the chemical pickling type
  • mechanical for example by brushing or sandblasting
  • the patent EP1391249 describes a culinary article coated with a network of metallic oxide in which a hydrophobic substance is uniformly distributed.
  • the substrate on which the metal oxide coating is applied can be activated beforehand by a plasma treatment.

  • the Applicant has developed a plasma surface treatment which allows the formation of a chemically activated interface layer between the support and the non-stick coating (generally obtained by spraying or by screen printing, roller, etc.), this interface layer allowing the anchoring of such a thickness of non-stick coating, which thus allows the latter to ensure a long-term non-stick function without the risk of delamination.
  • the subject of the present invention is an article comprising a support having an at least partially metallic contact surface and which is covered by a non-stick coating comprising at least one thermostable binder.
  • the contact surface comprises an interface layer chemically activated by plasma and formed by plasma polymerization
  • the thermostable binder of the non-stick coating is a fluorocarbon resin or a mixture of fluorocarbon resins, alone or as a mixture. with a thermostable bonding binder and resistant to at least 200 ° C, the fluorocarbon resin and, if necessary, the thermostable bonding binder forming a sintered network.
  • the non-stick coating has a thickness of 400 nm or more, and preferably between 2 and 50 ⁇ m.
  • the fact that the interface layer is chemically activated allows the anchoring on the support of a thick non-stick coating. If the interface layer was not chemically activated, for example simply roughened and cleaned by a plasma treatment as taught by international applications WO 03/035154 and WO 2008/146025 , it would not be possible to deposit such thick layers of fluorocarbon resin.
  • the fluorocarbon resin can 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% by mole of tetrafluoro , and mixtures thereof.
