Abstract

One subject of the present invention is a utensil (1) comprising a support (2) having a contact surface (21) that is at least partially metallic and that is covered by a non-stick coating (3) based on a fluorocarbon resin. The contact surface (21) comprises an interface layer (210) that is chemically activated by plasma. Another subject of the present invention is a process for manufacturing such a utensil (1).

Description

technical field [0001] The present invention generally relates to articles comprising a non-stick coating having improved carrier adhesion properties. The invention also relates to a method of preparing said cooking utensil. Background technique [0002] The field to which the invention relates is mainly cooking utensils, such as frying pans or saucepans, but the invention can also relate to any other surface with a non-stick coating, such as the soleplate of an iron. [0003] On the inner surfaces of cooking utensils, relatively thick coatings (typically having a total thickness between 10-50 μΌ) made of sintered fluorocarbon resins (eg PTFE) are usually used as non-stick coatings. This coating is known not only for its non-stick properties, but also for its resistance to chemical or thermal stress. However, this coating has limited adhesion to metal supports, especially supports made of aluminium, stainless steel or cast iron. [0004] In order to overcome these problem...
