Abstract
A urethane coating is formed by a reaction of a hydroxy-functional resin and a blocked isocyanate crosslinker. A method of catalyzing this reaction includes forming a polymeric ligand from the resin and/or the crosslinker. The method also includes incorporating a metal catalyst with the polymeric ligand to complex the metal catalyst with the polymeric ligand. The method further includes reacting resin and the crosslinker to form the urethane coating.
