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.
