Beschreibung
Zusammenfassung:	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 in aqueous media to yield a silylurethane, introducing 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 the silylurethane and the aminodisilane. The aqueous mixture of the silylurethane and the aminodisilane together constitute a coating composition that, upon curing, forms a dry-erase coating.
