Provided is a culinary item, one surface of which is provided with a coating including at least one rare-earth oxide layer. Such a coating has the specific feature of not only having mechanical hardness and abrasion resistance comparable to those of enamels and ceramics, but also excellent intrinsic hydrophobic properties that enable the coating obtained to have a non-stick property that is comparable to that of fluorocarbon coatings and suitable for culinary applications.

Culinary item comprising a rare earth oxide layer

A method of manufacturing an item, notably a culinary item, includes: providing a support in the form of a preform; preparing a sol-gel composition; hydrolyzing the sol-gel precursor, followed by a condensation reaction; applying onto at least one support surface of the preform at least one layer of the sol-gel composition to form a sol-gel coating layer; and thermally treating the sol-gel coating layer to solidify the coating layer. Further, before thermally treating the sol-gel coating, the method includes pre-densifying the coated preform and stamping the preform to produce a final form of the culinary item.

The present invention generally relates to anti-stick coatings for cooking utensils, which exhibit improved properties of hydrophobicity and resistance to high temperature. The present invention also relates to a culinary article comprising a support coated in said coating, and a process for applying on the support such a coating according to the invention.

Non-stick coating with improved hydrophobic properties

Provided is a cooking item, at least one of the surfaces of which has a fluorocarbon coating including rare earth oxide fillers. The use of a composition including a fluorocarbon resin and rare earth oxide fillers makes it possible to obtain coatings, the mechanical properties of which (particularly in terms of hardness and resistance to abrasion) are reinforced without any breakdown in the non-stick properties of said composition. Also provided is a method for manufacturing such a cooking item.

Provided is a method for decorating a kitchen item by means of mechanical treatment in order to produce a decoration. The mechanical treatment involves removing and/or displacing part of a thermostable decorative composition by means of pressure and moving a tool or a compressed air jet over the surface of the decorative layer.

Method for decorating a kitchen item by mechanical treatment

Provided is a primer composition for a non-stick coating which includes a polyamide-amic acid having an acid value of 50 to 200 mg KOH/g, a Lewis base, water and at least 5 wt % of a polar aprotic solvent relative to the total weight of said composition. According to the invention, the weight ratio of PAI/polar aprotic solvent in said composition is at least 1.5. Also provided is a method for preparing such a composition, and a method for manufacturing an item comprising a metal substrate to which such a composition is applied.

Primer compositions for non-stick coatings and method for manufacturing same

Provided is an article, particularly culinary, comprising a cast iron support having two opposite sides. The article comprises a vitreous coating in the form of at least a continuous layer of a sol-gel material comprising a matrix formed from at least a metal polyalkoxylate and at least a reactive or unreactive silicone oil, the layer of sol-gel material being deposited directly on one at least of the sides of said support, and the side provided with a vitreous coating has a surface roughness Ra ranging between 3 and 15 &#x3bc;m with a peak count per centimeter RPc ranging between 50 and 200. A method for manufacturing such an article is also provided.

Provided is a vitreous coating comprising at least one layer embodied in the form of a continuous film of sol-gel material comprising a matrix formed from at least one metal polyalkoxylate and wherein anisotropically-shaped particles are dispersed, said layer comprising at least one area wherein the particles are particles predominantly inclined by an angle (&#x3b1;) of between 20&#xb0; and 90&#xb0; relative to the median plane of the film. The subject matter of the present invention also comprises a method of manufacturing such a coating, and a culinary article one of the surfaces of which is coated with such a coating.

Sol-gel coating comprising anisotropic particles and culinary article provided with such a coating

Provided is a ceramic coating intended to be applied on a metal support and having the form of at least a continuous film having a thickness between 2 and 100 &#x3bc;m, this coating comprising a matrix including at least a metal polyalkoxide and wherein are dispersed particles whereof the diameter ranges between 0.01 and 50 &#x3bc;m, said particles being from a material having a thermal conductivity equal to or higher than 10 W&#xb7;m&#xb7;Kand a bulk density of at the most 3.9 g/cm. Also provided is an article, for example culinary, comprising such a coating and its method of manufacture.

Ceramic coating with scratch resistance and thermal conduction properties

A cooking item including a vitreous coating with improved impact-resistance properties, and a method for manufacturing such an item. The method for manufacturing includes optionally treating a concave internal side of a substrate having the end shape of the cooking item, the concave internal side being arranged on the side of the food to be introduced in said item, and a convex exterior side to be arranged on the heat source side, so as to obtain a treated internal side adapted to cause a hard base layer to adhere to the substrate, The method further includes preparing an adhering hard base layer on said internal side of the substrate, be it treated beforehand or not, and preparing a non-stick coating on the hard base layer.

Cooking item comprising a non stick coating with improved properties of adhesion to the substrate

The present invention relates to a cooking item comprising a vitreous coating with improved impact-resistance properties. The present invention also relates to a method for manufacturing such an item.

Cooking item comprising a non-stick coating with improved properties of adhesion to the substrate

A cooking item comprising a vitreous coating with improved impact-resistance properties. The present invention also relates to a method for manufacturing such an item.

This invention relates to an article () including a substrate () including two opposite faces (), and a sol-gel coating () covering at least one of the faces () of said substrate (), in which said sol-gel coating () is in the form of a continuous film of a material including a matrix formed by at least one metal polyalkoxylate and at least 5% by weight with respect to the total weight of the coating () of at least one metal oxide dispersed in said matrix.
