    • 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.
    • 涂布在其上涂布有溶胶 - 凝胶膜层的基材的涂布体系包括涂覆在溶胶 - 凝胶膜上方的残留的高酸值涂层,而没有中间粘合层。 残留的高酸值涂料组合物可以是溶剂型组合物,其在固化时具有高水平的残余游离酸基团,相当于大于约65mgKOH / g的酸值。 残留的高酸值涂层可以包括残留的高酸值树脂,即固化具有残留游离酸基团的树脂,相当于大于约65mgKOH / g的酸值。 残余的高酸值树脂可以是多元醇和合适的交联剂如聚酐或多异氰酸酯交联剂或其混合物的反应产物。 残留的高酸值涂料组合物可以包括不透明颜料和缩合催化剂。
