    Abstract: The present invention provides a coating composition, a method of coating a substrate, and a coated substrate, (e.g., a coated cement fiberboard article). In preferred embodiments the coating composition includes one or more latex polymers and an aliphatic epoxy resin system, The coating composition can include one or more coating compositions that may be applied in one or more layers. A coated article comprising a cement fiberboard substrate and a coating system applied to the substrate is also provided, The article includes a first coating system applied to the substrate, wherein the first coating system includes an aliphatic epoxy resin system having an aqueous dispersion of polymer particles, optionally a silicate additive, and optionally one or more olefinic compounds and initiator for same, The first coating system preferably includes one or more coating compositions that may be applied in one or more layers, In a preferred embodiment, the first coating system is applied to all the surfaces of the substrate (e.g., the front side, back side and edges of a board). The coated substrate may then be coated with other optional coatings, e.g., decorative or protective topcoats,

    Abstract: A coated article is provided that includes a cement composite substrate; and a coating system applied to the substrate. The coating system includes an epoxy-functional coating composition applied to the substrate, and a water-based coating composition, distinct from the epoxy-functional coating composition, applied to the epoxy-based coating, between the compositions. A method is also provided that includes the steps of: providing a cement composite substrate; applying an epoxy-functional coating composition to the substrate; and applying a water-based coating composition, distinct from the epoxy-functional coating composition, to the epoxy-based coating. The water-based coating composition used in this method preferably comprises a polymer having one or more functional groups that can react with the epoxy-based coating to promote adhesion between the compositions.

    Abstract: Un artículo revestido que incluye un sustrato de compuesto; y un sistema de revestimiento al sustrato. El sistema de revestimiento incluye un composición de revestimiento que funciona con pegamento aplicada al sustrato, y una composición de revestimiento con base en agua, distinta de la composición de revestimiento funcional con pegamento, aplicada al revestimiento con base en pegamento, entre las composiciones. También se proporciona un método que incluye los pasos de: proporcionar un sustrato de compuesto de cemento; aplicar una composición de revestimiento funcional con pegamento al sustrato; y aplicar una composición de revestimiento con base en agua, distinta de la composición de revestimiento funcional con pegamento, al revestimiento con base en pegamento. La composición con base en agua utilizada en este método preferiblemente comprende un polímero que tiene uno o más grupos funcionales que pueden reaccionar con un revestimiento con base en pegamento para promover la adhesión entre las composiciones.
