ENVIRONMENTAL ETCH RESISTANT, ONE-COMPONENT, COATING COMPOSITION, METHOD OF COATING THEREWITH, AND COATING OBTAINED THEREFROM ABSTRACT OF THE DISCLOSURE A one component composition suitable for coating a substrate, including at least one crosslinker having a functionality thereon that is reactive with a functionality on at least one film forming polymer. The crosslinker includes at least one member selected from the group consisting of: blocked isocyanurates of isophorone diisocyanate; derivatives of blocked isocyanurates of isophorone diisocyanate; blocked biurets of isophorone diisocyanate; derivatives of blocked biurets of isophorone diisocyanate. The composition preferably includes a blend of this crosslinker with a second crosslinker, wherein the second crosslinker is at least one member selected from the group consisting of: blocked isocyanurates of hexamethylene diisocyanate; derivatives of blocked isocyanurates of hexamethylene diisocyanate: blocked biurets of hexamethylene diisocyanate; and derivatives of blocked biurets of hexamethylene diisocyanate. The invention also pertains to a process for coating a substrate using the composition, as well as to a cured coating formed by the process of the present invention. 27
