摘要： A coating system for application to a substrate having a sol-gel film layer applied thereon includes a residual high acid value coating coat applied on top of the sol-gel film without an intervening adhesion layer. The residual high acid value coating composition may be a solvent borne composition that when cured, has a high level of residual free acid groups, equivalent to an acid number of greater than about 65 mgKOH/g. The residual high acid value coating may include a residual high acid value resin namely, a resin that cures having residual free acid groups, equivalent to an acid number of greater than about 65 mgKOH/g. The residual high acid value resin may be the reaction product of a polyol and a suitable crosslinker, such as a polyanhydride or polyisocyanate crosslinker or blend thereof. The residual high acid value coating composition may include opacifying pigments and condensation catalysts.

摘要： A coating system for application to a substrate having a sol-gel film layer applied thereon includes a decorative color coat applied directly on top of the sol-gel film without an intervening adhesion layer. The decorative color coat may be a solvent borne composition including a resin which is the reaction product of a crosslinked polyepoxy resin and a polyamine crosslinker, and one or more opacifying pigments. Decorative designs may be formed by selectively applying more than one layer of decorative color coats having different colors. A transparent clearcoat may be applied to the decorative film.
摘要翻译：用于施涂到其上涂覆有溶胶 - 凝胶膜层的基材上的涂料体系包括直接施加在溶胶 - 凝胶膜上的装饰性彩色涂层，没有插入粘合层。装饰性着色涂层可以是溶剂型组合物，包括作为交联聚环氧树脂和多胺交联剂的反应产物的树脂和一种或多种不透明颜料。装饰性设计可以通过选择性地应用具有不同颜色的多于一层的装饰性颜色涂层来形成。透明透明涂层可以施加到装饰膜上。
