  • Patent number: 10767080
    Abstract: Disclosed is a coating composition suitable for coating onto a wall or other substrate to yield a dry-erase coating, The composition may be prepared by reacting an excess amount of an aminosilane with a carbonate, an epoxy alcohol, or both in aqueous media to yield a silylurethane, and/or a silylamino polyol. In some approaches, the compositions and/or methods may further include an epoxysilane, and allowing the epoxysilane to react with the aminosilane to yield an aminodisilane. This reaction will result in a coating composition that comprises one of a silylurethane, a silylamino polyol, or both, and the aminodisilane. The aqueous mixture of the silylurethane, the silylamino polyol, or both, and the aminodisilane together constitute a coating composition that, upon curing, forms a dry-erase coating.

  • Patent number: 10752803
    Abstract: A coating composition can be made by providing an aminoalkoxysilane and, in the substantial absence of water, reacting at least a portion of the aminoalkoxysilane with at least one epoxide-containing compound including an aliphatic group to yield at least one alkoxysilylamine, and then reacting the alkoxysilylamine with at least one isocyanate reagent containing at least two isocyanate groups to yield a monomer having plural alkoxysilane groups and, in many embodiments, at least two branched aliphatic groups having at least six carbon atoms. A coating composition thus formed exhibits high durability and good flexibility. Also disclosed is a method of applying a coating composition to a substrate and allowing the coating composition to cure, and the cured coating resulting from such application.

  • Patent number: 10745566
    Abstract: A coating composition comprises at least one solvent, at least one resin, and at least one filler, wherein the filler is silica-deficient, sodium-potassium alumina silicate. The silica-deficient filler may be a sodium-potassium alumina silicate that contains less than 0.1 percent by weight crystalline silica and is 5 percent by weight or less of the coating composition or 1 percent by weight or less of the coating composition. In the later instance, the coating composition contains less than 0.001 percent crystalline silica. The resin may comprise styrene, styrenic copolymers, or mixtures including styrene. The composition provides a temporary gloss coating that may be removed physically, as by peeling for example. A method for coating a substrate with a coating that maybe removed by physical means is also provided. The method comprises applying the disclosed coating composition.

  • Publication number: 20200215570
    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.
