A method for making pots and pans, equipped with a multi-layer coating of non-stick material including the forming of multiple layers of coating of an inner surface of a wall delimiting a cooking cavity, performed by cyclical repetition of a step of applying suitable substances and subsequent drying and baking in an oven of said layers of substances applied, at least the final layer of said substances being obtained by using a non-stick substance. The method includes, before the step of applying the substance for forming at least the final layer coating the cooking cavity of the pot, a step of adding as an additive edible oil or grease to the liquid substance to be applied for forming said final layer.

Provided are low coefficient of friction fluoropolymer one coat coatings having a relatively low bake temperature. The fluoropolymer coatings contain high temperature resistant polymer binder, low melting tetrafluoroethylene/hexafluoropropylene copolymer having a melting point of below 255 C. by the method of ASTM D 4591, and low molecular weight polytetrafluoroethylene having a heat of crystallization of at least about 50 J/g.

Heat resistant and/or nonstick polymer materials and composites, and cookware including a food support surface comprising an integrated or attached cooking surface formed of the materials and composites. The cookware can includes a melt-processible fluoropolymer surface or insert. The cookware can further include a laminate material with structural rigidity, wherein the laminate material includes a flexible substrate impregnated with the heat resistant polymer material, coated with a nonstick coating, and pressed or molded in a shaped cookware or other nonstick items or component. Various cooking devices can be pressed from the material, as well as oven or vehicle components.

The present application discloses a physically non-stick structure and a cooking utensil applied on a surface of a metal substrate, the physically non-stick structure includes a concave structure and a convex structure on at least a part of an area of the concave structure, at least a part of a surface of the concave structure and/or at least a part of a surface of the convex structure are provided with a physical vapor deposition layer, and a morphology of a surface of the physical vapor deposition layer is similar to a morphology of the surface of the concave structure and/or the surface of the convex structure covered by the physical vapor deposition layer.

A non-stick metal vessel and a non-stick cooking utensil. The non-stick metal vessel includes a body. An inner surface of the body is constructed to exhibit a micro-level roughened texture. The micro-level roughened texture is coated with a PVD multi-metal film. The PVD multi-metal film is configured to be capable of creating a low surface energy micro-nano porous oil-locking structure. This disclosure possesses commendable advantages in terms of health and environmental friendliness. Furthermore, it offers remarkable anti-adhesive properties, exceptional hardness, outstanding wear resistance, and an extended lifespan.

Cookware surfaces of metal, such as aluminum, may include a nonstick coating and embedded hard metal mesh. The mesh protects the nonstick coating between interior regions within the mesh from being cut or abraded by knives and other tools.

Provided is a metal-dioxide nanofiller including at least two graft chains, at least one of the chains being a hydrophilic and the other being a hydrophobic chain compatible with fluorinated polymers. The hydrophobic chain is an oligomer, the weight-average molar mass Mw of which is between 300 and 20, 000 g/mol-1 .Math. Also provided is a non-stick coating comprising such a filler, as well as to a culinary article provided with such a coating.

A baking apparatus has a substantially rectangular baking basket for holding one or more food items supported by a substantially rectangular tray. The tray has a base and a container wall extending upward therefrom and forming an upper lip. The basket has a mesh cradle portion defining a plurality of openings. The mesh cradle portion has a bottom surface and cradle wall extending upwards from the bottom surface and forming, at an upper end, an upper periphery. A solid and continuous support rim is coupled to the upper periphery. Handles extend off the support rim. A series of support members extend from the support rim and hold the basket in a position elevated from the tray. The tray captures discharges from the one or more food items and prevents warping. The tray and basket allow air to circulate substantially freely around the one or more food items.

The present invention relates to a cooking device including a metal holder supporting a ceramic cooking surface, the holder having a hardness no lower than 150 HV. The holder forms a substrate supporting a surface layer made of a transition metal boride or boronitride forming the cooking surface. The present invention further relates to a culinary article including a cooking device of the type above-mentioned, a household cooking appliance including a cooking device of the type above-mentioned, as well as a method for producing a cooking device of the type above-mentioned.

Provided is a metal-oxide nanofiller including at least two graft chains, at least one of the chains being hydrophilic and the other being a hydrophobic chain compatible with fluorinated polymers. The hydrophobic chain is an oligomer, the weight-average molar mass Mw of which is between 300 and 20,000 g/mol.sup.1. Also provided is a non-stick coating comprising such a filler, as well as to a culinary article provided with such a coating.
