摘要 |
<p>A two component composition suitable for coating a substrate comprises at least one crosslinker having a functionality thereon which is reactive with a functionality on at least one film forming polymer present in a separate component of the composition. The crosslinker comprises at least one member selected from the group consisting of: (1) an isocyanurate of isophorone diisocyanate; (2) a derivative of an isocyanurate of isophorone diisocyanate; (3) a biuret of isophorone diisocyanate; and (4) a derivative of a biuret of isophorone diisocyanate. The composition preferably comprises a blend of the crosslinker with a second crosslinker, wherein the second crosslinker is at least one member selected from the group consisting of: (1) an isocyanurate of hexamethylene diisocyanate; (2) a derivative of an isocyanurate of hexamethylene diisocyanate; (3) a biuret of hexamethylene diisocyanate; and (4) a derivative of a biuret 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.</p> |
