Abstract: A method for producing metal patterns, which includes depositing a temporary protection on a substrate surface corresponding to the negative of the patterns to be produced; depositing at least one metal on the areas corresponding to the patterns to be produced; and eliminating the temporary protection at least partly during and/or after, or at least partly during and/or after the deposition step. The method can produce decorative objects or functional objects such as printed circuits, integrated circuits, RFID chips, and electronic reader-readable encoding pictograms. A set of consumables used to implement the method is also disclosed.

Abstract: A method of metallizing the surface of a substrate electrolessly, by spraying one or more oxidation-reduction solutions thereonto. The steps of this method include: a) physical or chemical treatment to reduce the surface tension of the substrate before metallization; b) electroless metallization of the surface of the substrate treated in step a), by spraying one or more oxidation-reduction solutions in the form of one or more aerosols thereonto; and c) formation of a top coat on the metallized surface. Compact devices for implementing this method and the products obtained are also disclosed.
Abstract: The invention relates to a non-electrolytic method for metallizing a substrate by projecting an aerosol containing a solution of an oxidant metallic cation and of a reducing agent; said method comprising a step of -a- wetting the substrate; starting to project a metallisation according to a succession of projecting phases alternating with relaxing phases: (i) by adjusting the duration Dp of the projection phases and the duration Dr of the relaxing phases from a metallisation constant k intrinsic for each metal; and (ii) by adjusting the projection flow-rate. The metallisation projection is carried out dynamically by displacing projection means relative to the substrate in order to carry out a periodical scanning, wherein Dp correspond to the duration during which the surface unit in question is submitted to the continuous projection of the aerosol and Dr corresponds to the duration during which the part is not submitted to projection.
Abstract: The present invention relates to a corrosion-resistant “all-metal” mirror, including: a glass substrate; a silver coating with a thickness eAg deposited on at least one surface of the substrate by a non-electrolytic metallization that comprises spraying, onto the substrate surface, at least one aerosol containing silver in cation form (oxidizer) and at least one reducing agent capable of converting the silver cation into metal; at least one protective layer (C) containing at least one metal other than silver and deposited on the silver coating. The protective layer has a thickness em such that 0.3 eAg?eM?5 eAg, and is obtained by a non-electrolytic metallization of the silver coating being carried out by spraying, onto the silver coating, at least one aerosol containing at least one metal, other than silver, in cation form (oxidizer), and at least one reducing agent capable of converting the metal cation into metal.
Abstract: A surface treatment process which enables a substrate (polymer) to be given specific physical properties, especially surface nanoporosity, for example with a view to electroless metallizing it, and which completely replaces surface treatment by sulfo-chromic pickling. The surface treatment includes a hybrid UV/corona treatment of the substrate surface followed by non-electrolytic metallization. A device for implementing these processes is also disclosed.
