    • An automotive quality paint coat is laminated to the exterior surface of a molded plastic car body member or panel. In one embodiment, the paint coat includes an exterior clear coat above a color coat. During processing, the clear coat and color coat are each coated on a temporary flexible casting sheet and dried. A high gloss surface is transferred to the clear coat from the casting sheet. The paint coat is then transferred from the casting sheet to a thin, semi-flexible thermoformable plastic backing sheet by dry paint transfer-laminating techniques. The resulting laminate is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article. The paint coat has sufficient elongation to retain exterior automotive appearance and durability properties during thermoforming without deglossing. The backing sheet absorbs defects in the substrate material so the paint coat retains its appearance and durability properties during the injection-cladding step. The finished article comprises a high gloss, defect-free paint coat on the exterior of a molded plastic car body member or panel. Solution-form polyvinylidene fluoride/acrylic paint systems have remarkably high combined gloss and distinctiveness-of-image levels, together with durability properties required for exterior automotive use.
    • 将汽车优质涂料层合到模制塑料车身部件或面板的外表面上。 在一个实施方案中,涂料包括在彩色涂层上方的外部透明涂层。 在加工过程中,将透明涂层和彩色涂层各自涂覆在临时柔性铸片上并干燥。 高光泽表面从铸片转移到透明涂层。 然后通过干漆转印层压技术将涂料从铸片转移到薄的半柔性可热成形的塑料背衬片材上。 将所得的层压体热成型为汽车车身件或面板的复杂三维形状。 然后通过注射包层技术将预成型的层压板粘合到下面的塑料基材上,以形成成品。 涂层具有足够的延伸率,以保持外部汽车外观和热成型时的耐久性,而不会发生变形。 背衬片吸收衬底材料中的缺陷,使得涂层在注射包层步骤期间保持其外观和耐久性能。 成品包括在模制的塑料车身构件或面板的外部上的高光泽,无缺陷的油漆涂层。 溶液型聚偏二氟乙烯/丙烯酸漆系统具有非常高的组合光泽度和独特的图像水平,以及外部汽车使用所需的耐久性。

    • An automotive quality paint coat (44) is laminated to the exterior surface of a molded plastic car body member or panel (118). In one embodiment, the paint coat (44) includes an exterior clear coat (45) above a color coat (46). During processing, the clear coat (45) and color coat (46) are each coated on a temporary flexible casting sheet (42) and dried. A high gloss surface is transferred to the clear coat (45) from the casting sheet (42). The paint coat (44) is then transferred from the casting sheet (42) to a thin, semi-flexible thermoformable plastic backing sheet (72) by dry paint transfer-laminating techniques. The resulting laminate (70) is thermoformed into a complex three-dimensional shape of the car body member or panel. The preformed laminate (116) is then bonded to an underlying plastic substrate material, by injection-cladding techniques, for example, to form the finished article. The paint coat (44) has sufficient elongation to retain exterior automotive appearance and durability properties during thermoforming without deglossing. The backing sheet (72) absorbs defects in the substrate material so the paint coat retains its appearance and durability properties during the injection-cladding step.
