    摘要： The present invention is related to a method for applying a coating (4) on a substrate (1), comprising the steps of: - scanning a laser beam (2) along a line on the surface of said substrate, - supplying a coating forming material from a supply system (3), said system moving along the same line as the laser beam but coming up behind the laser beam, so that the coating forming material is deposited on a spot which has previously been heated by the laser beam to a temperature above the melting temperature of the coating forming material, wherein substantially no physical contact occurs between the laser beam and the coating forming material. Preferably, the method further comprises a second step of scanning the surface a second time with said laser beam, without adding coating forming material during the second step.

    摘要： The present invention provides powder coating finishes comprising inter-mixed basecoat and color layers of coating powders, wherein the basecoat layer has a first color and one or more color layers has one or more accent color different from the first color. In the finishes, each of the first color and the one or more accent color is visible in the said finish to provide three-dimensional appearing antique look, swirl look and marbleized patterns. One or more of the coating powders used to form the finish may comprise a texture forming coating powder. Further, weatherable powder coating finishes comprise one or more protective powder coating layer between the substrate and basecoat color layer. In addition, the present invention provides methods for producing patterned powder coating finishes comprising applying to the substrate one or more basecoat coating powder layer having a first color, applying dry-on-dry one or more accent color coating powder layer over the basecoat powder layer, forming patterns in the resulting layers of coating powder, such as with one or more flat bristle brushes, and curing to form powder coating finishes.

    摘要翻译： 本发明提供粉末涂料涂层，其包括混合底涂层和涂层粉末的彩色层，其中底涂层具有第一颜色，并且一个或多个颜色层具有不同于第一颜色的一种或多种颜色。 在完成中，第一种颜色和一种或多种口音颜色中的每一种在所述饰面中是可见的，以提供三维出现的古董外观，漩涡外观和大理石纹理。 用于形成整理剂的一种或多种涂料粉末可以包含织构形成涂层粉末。 此外，耐候性粉末涂料涂层在基材和底漆着色层之间包含一个或多个保护性粉末涂层。 另外，本发明提供了制造图案化的粉末涂料表面处理的方法，其包括将一个或多个具有第一颜色的底涂层粉末层施加到基底上，将干燥的干燥的一个或多个重彩涂层粉末层涂覆在底涂层粉末层上 在所得到的涂层粉末层中形成图案，例如用一个或多个平头刷毛，并固化以形成粉末涂层表面。
