    Abstract: Coating compositions for cementitious substrates may be made from a multistage latex polymer; silane; and a water-soluble acid, acid anhydride or acid salt capable of etching or otherwise reacting with the surface of the substrate to provide coating adhesion. The silane my be present as a silane coupling agent distinct from the multistage latex polymer, or may be present as silane functionality on the multistage latex polymer. The coating compositions adhere well to cementitious substrates and have a self-etching capability to provide coating adhesion, especially near edges and corners.

    Abstract translation: 水泥基材的涂料组合物可以由多级胶乳聚合物制成; 硅烷; 以及能够蚀刻或以其它方式与基材表面反应以提供涂层附着力的水溶性酸,酸酐或酸盐。 硅烷作为不同于多级胶乳聚合物的硅烷偶联剂存在,或者可以作为硅烷官能团存在于多级胶乳聚合物上。 涂料组合物很好地粘附到水泥质基材上,并且具有自蚀刻能力,以提供涂层附着力,特别是在边缘和角落附近。
