摘要
One subject of the present invention is a method of metalizing the surface of a substrate electrolessly, by spraying one more oxidation-reduction solutions thereonto, which method is industriallizable, automatable, clean, multi-substrate and optimized in terms of adhesion and decorative appearance. To achieve this, the method involves the following steps: 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 metalized surface. Other subjects of the invention are the compact devices for implementing this method and the products obtained, namely in particular: hollow glass flasks, especially for cosmetic use; automotive parts; parts for home electronics or for aeronautics; and electronic parts such as conducting tracks, radio frequency label antennas or coatings for electromagnetic screening.
