Abstract
La presente invención se refiere a mejoras a proceso mejorado para aplicar un recubrimiento compuesto a un sustrato, dicho proceso comprende aplicar al sustrato una composición formadora de película coloreada para formar una capa de base, y aplicar a dicha capa de base una composición formadora de película transparente para formar una capa superior transparente sobre la capa base; por el calentamiento de el recubrimiento compuesto a una temperatura suficiente para proporcionar un fraguado efectivo; la mejora que comprende el que la capa transparente y/o de base contenga una composición termofraguable a base de solvente de sólidos altos que comprenda: a) un poliepoxido-funcional de peso molecular bajo, b) un agente de fraguado consistiendo esencialmente de una anhídrido, c) un catalizador de fraguado: dicha composición está caracterizada porque es fraguable en la ausencia de un agente de fraguado de melamina.The present invention relates to improvements to an improved process for applying a composite coating to a substrate, said process comprising applying to the substrate a colored film-forming composition to form a base coat, and applying to said base layer a film-forming composition clear to form a transparent top coat over the base coat; by heating the composite coating to a temperature sufficient to provide effective setting; the improvement that the transparent and / or base layer contains a thermosetting composition based on high solids solvent comprising: a) a low molecular weight functional polyepoxide, b) a setting agent consisting essentially of an anhydride , c) a setting catalyst: said composition is characterized in that it is settable in the absence of a melamine setting agent.
