A dual-layer coating for application in a steam-generating device is disclosed. A impermeable first layer thermally insulates the heated surface, while a second, porous layer enlarges the contact area, leading to an efficient conversion of liquid into vapor.

Coating for a steam-generating device

A method of preparing a light-absorbing layer applied to a lamp vessel of an electric lamp. At least a part of the lamp vessel is provided with a light-absorbing coating which has stabilized pigments incorporated in a sol-gel matrix. In order to stabilize the pigments, an aminosilane is added.

Method of preparing a light-absorbing coating

Disclosed is a layer for use in a domestic appliance, based on a sol-gel precursor. This layer can be obtained by screen-printing and comprises an organosilane compound. The layer is obtained from a concentrated pre-polymerized sol-gel precursor. The layer can be used as an insulating layer or as a conductive layer in a heating element. Furthermore, the layer can be used for decorative purposes.

Layer for use in a domestic appliance

A heating element includes an electrically insulating layer and an electrically conductive layer. At least the electrically conductive layer is based on a hybrid sol-gel precursor including an organosilane compound.

Sol-gel based heating element

A sol-gel coating composition comprising fluoropolymer particles is disclosed. The fluoropolymer particles are distributed homogeneously in the coating, leading to scratch-resistant anti-stick and low-friction coatings that are suitable, for example, for electrical and non-electrical domestic appliances.

Fluoropolymer-containing sol-gel coating

Disclosed is medical equipment, the surface of which being at least partially provided with a coating which is provided by means of a sol-gel process. By applying such coating staining of the medical equipment by iodine-containing agents is prevented. The sol-gel coating can be cured at a curing temperature of 80&#xb0; C. or lower. The medical equipment can, for example, comprise a tabletop of a diagnostic system.

Medical equipment provided with a coating

A sol-gel material with metal particles which can be used as a conductive adhesive for systems that have a high operating temperature is disclosed. The material is especially suitable for appliances equipped with a flat heating element, such as steam irons.

Thermally resistant adhesive

The invention pertains to a composition comprising silver metal particles and an additive, characterized in that the additive is a silane derivative comprising at least one methyl group and at least one alkoxy group. Preferably, the silane derivate is methyl trimethoxysilane, methyl triethoxysilane, or a mixture thereof. The compositions can be used to make thermal resistant conductive silver-containing layers, for instance for use in AMLCD.

Colloidal solution comprising silver metal particles and a silane derivative

An electric lamp includes a light-transmitting lamp vessel which accommodates a light source. At least a part of the lamp vessel is provided with a light-absorbing coating which has stabilized pigments that are incorporated in a sol-gel matrix. Aminosilane is included in order to stabilize the pigments.
