Patent number: 6333077Abstract: A process for lacquer coating substrates with a colored and/or effect base lacquer and a clear lacquer topcoat, in which a colored and/or effect base lacquer layer of a base lacquer coating composition is applied onto a substrate and is provided in a wet-on-wet process with a clear lacquer coating. Before being jointly stoved or jointly cured with the base lacquer layer, the uncured clear lacquer layer is exposed to high-energy radiation. In the clear lacquer coating composition, the resin solids content contains 50 to 98 wt. % of a system A) thermally curable by addition and/or condensation reactions, which system contains substantially no free-radically polymerisable double bonds and substantially no groups capable of reacting in another way with free-radically polymerisable double bonds of a system B). The resin solids content further contains 2 to 50 wt.Type: GrantFiled: November 22, 1999Date of Patent: December 25, 2001Assignee: Herberts GmbH & Co. KGInventors: Karin Maag, Karl-Friedrich Dössel

Patent number: 5981696Abstract: The invention concerns a process for preparing coating powder compositions in which one or a plurality of base resins and one or a plurality of hardeners, each of which is in solid form, is dissolved with a low-molecular compound above its critical pressure and critical temperature. This low-molecular compound is inert with respect to the base resins and hardeners and is in gaseous form under normal operating conditions with respect to pressure and temperature. The pressure of the resultant solution is then reduced, for example, by spraying. The resultant coating powder composition can be sprayed directly onto a substrate to be coated. Coating powders can also be recycled according to the process of the invention.Type: GrantFiled: February 10, 1997Date of Patent: November 9, 1999Assignee: Herberts GmbHInventors: Dietrich Saatweber, Karin Maag, Wolfgang Diener, Peter Klostermann, Thomas Berger

Patent number: 5932282Abstract: A process for producing a repair coating This invention relates to a process for producing a multi-layer repair coating by the application of a transparent clear lacquer coat, which is unpigmented or which contains colourless pigment, to a predried or hardened colour- and/or effect-imparting base pigment coat, or by the application of a pigmented covering lacquer coat to an optionally precoated substrate. Binder vehicles which are hardenable exclusively by radical polymerisation are used for the production of the transparent clear lacquer coat or of the pigmented covering lacquer coat, and hardening is effected by means of pulsed, high-energy UV radiation.Type: GrantFiled: August 29, 1997Date of Patent: August 3, 1999Assignee: Herberts Gesellschaft mit beschrankter HaftungInventors: Wolfgang Diener, Peter Klostermann, Frank-Jurgen Krumpolt, Christine Kurz, Karin Maag, Hans-Ulrich Simmrock, Werner Lenhard
