Polymerfolie overtrukket med lak og fremgangsmåde til påføring af den overtrukne polymerfolie på formlegemer

摘要

A polymer foil coating lacquer consists of, wt.%, (A) 18-45 binder compsn. comprising 10-70 polyurethane resin, 5-40 melamine resin, 10-60 further binder component and 0-6 thickener, (B) 0.10-10 Al and/or mica effect platelets, (C) 0-15 coloured pigment, (D) organic solvent and (E) 50-76.9 water. The pref. thickener is an acrylic resin or PVA and is present to 0.1-3 wt.%. Preferred deformation test (DIN-ISO 1,520) comprises deformation to a depth of 10 mm followed by relief results in a permanent deformation of 4.5-8 mm free from cracks. Pref. the foil is applied to the car part by: (a) an adhesive, (b) vacuum deep drawing or (c) covering a mould with the foil and injecting a curable moulding compsn.
