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.

Abstract: This invention relates to coating compositions that include water; a latex polymer and a silane coupling agent. The latex polymer preferably comprises acetoacetoxy functionality, or is a multistage latex, or is an acetoacetoxy functional multistage latex. The silane coupling agent is preferably a functionalized silane coupling agent (more preferably an epoxy-functional silane coupling agent). The compositions may be used to coat a variety of substrates, including wood, cement and fiber cement. Articles having the coating applied thereto are also provided.

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.
