Patent number: 9757929Abstract: A transfer laminate (35), comprising a carrier film having an adhering decorative element having a solid, pigmented, partially cured decorative layer, is laminated on the decoration side onto a substrate (40) having a temperature between 50 and 70° C. on the decoration side, on which substrate a coating that can be painted over has been applied in the course of a traditional process. The paint layer of the coating that was applied last is still moist and tacky after the intermediate drying thereof. The transfer laminate (35) is laminated onto the still moist and tacky paint layer on the substrate (40), and at least the region of the transfer laminate (35) containing the decorative element is pressed onto the substrate coating over the entire area at a pressure of 0.2 to 5.0 bar for 40 to 240 seconds. Then the carrier film is quickly cooled to a temperature less than 20° C. and then removed from the substrate coating, wherein the decorative element remains on the substrate coating.Type: GrantFiled: January 9, 2014Date of Patent: September 12, 2017Assignee: Karl Wörwag Lack-und Farbenfabrik GmbH & Co.

Patent number: 8828180Abstract: A method of applying a surface-coating material to a substrate includes providing a flexible laminate with a carrier and at least one layer of surface-coating material applied to the carrier and comprising a surface-coating material containing a double-bond-containing, OH-functional component A, a double-bond-containing, NCO-functional component B, and, optionally, a double-bond-containing component C which is different from A and B; applying a layer of adhesive to the substrate, contacting the carrier side of the laminate with a surface of the substrate such that the layer of surface-coating material is at least partially cured before or when it contacts the surface of the substrate, and removing the carrier from the layer of surface-coating material.Type: GrantFiled: February 11, 2013Date of Patent: September 9, 2014Assignee: Karl Wörwag Lack-und Farbenfabrik GmbH & Co. KGInventors: Terry Djunaldi, Helge Warta

Patent number: 5997941Abstract: A process for repairing relatively small paint faults in powder coating layers, in which, in the region of the faulty point, a cutout is introduced into the powder coating layer with precisely defined dimensions with respect to its area and also with respect to its depth. A filler made of powder coating and/or a pre-product of the powder coating is introduced into the cutout. The filler is dimensioned to correspond to the volume of the cutout, in particular corresponding to the dimensions of the cutout, and is coherent. The filler introduced is joined, in particular bonded, to the powder coating layer arranged outside the cutout.Type: GrantFiled: November 13, 1997Date of Patent: December 7, 1999Assignees: DaimlerChrysler AG, Eisenmann Maschinenbau KG, Micro Compact Car AG, Karl Woerwag Lack--und Farbenfabrik GmbH & Co.
