Abstract:
The present invention relates to a coated article, comprising: a cement composite substrate; and a coating system applied to the substrate, wherein the coating system comprises an aqueous blend comprising: (i) an epoxy resin; and (ii) a latex polymer, distinct from the epoxy resin; wherein the epoxy resin comprises at least one oxirane group; and the coating system comprises at least one epoxide-reactive functional compound that contains one or more epoxy-reactive functional groups that react with the oxirane group; and relates to a process for producing this article.
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:
The present invention provides a water-based coating and/or coating system that can be used to form sag resistant wet layers or coatings on a wide range of substrates. The coating system is particularly effective for protecting metal-containing substrates, such as intermodal cargo containers, against corrosion. As an overview, the present invention provides water-based compositions suitable to form primer coats on substrates. Desirably, the primer incorporates a high level of one or more CAS agents for excellent sag resistance while drying in a broad range of relative humidity environments. Alternatively, modifications can be made to control temperature and humidity during spray application and drying as a way to increase sag resistance of the coating.
