Culinary Article Comprising a Fluorocarbon-Resin Based Non-Stick Coating Having Improved Properties of Adhesion to the Support, and Method for the Production Thereof

摘要

The present invention relates to a cooking article a substrate having a contact surface at least partially made of metal and coated with a non-stick coating comprising at least one layer including at least one fluorocarbon resin alone or mixed with a thermostable coupling binder that is heat-resistant up to at least 200° C., the fluorocarbon resin and, if necessary, the thermostable coupling binder forming a sintered network. According to the invention, the contact surface comprises an interface layer consisting of a polymer layer formed by plasma polymerization from a precursor selected from among unsaturated carboxylic acids, the salts or esters thereof, saturated carboxylic acid vinyl esters, unsaturated dicarboxylic acids, the salts, esters, hemiesters or anhydride esters thereof, and unsaturated epoxides. The present invention also relates to a method for manufacturing such an article.

主权项

1. A culinary article comprising a support exhibiting a contact surface at least partially metallic and which is covered by a nonstick coating comprising at least one layer comprising at least one fluorocarbon resin alone or in admixture with a coupling binder which is heat stable and resistant to a temperature of at least 200° C., the fluorocarbon resin and, if necessary, the heat stable coupling binder forming a sintered network,
wherein said contact surface comprises an interface layer consisting in a polymer layer formed by plasma polymerization from a precursor selected from among unsaturated carboxylic acids, the salts or esters thereof, saturated carboxylic acid vinyl esters, unsaturated dicarboxylic acids, the salts, esters, hemiesters, or anhydrides thereof and unsaturated epoxides.
