Disclosed is a method for applying a film of a coating composition in liquid form onto a substrate which applied film cures rapidly at room temperature without heat curing. The coating composition comprises an aromatic hydroxyl-functional compound and a multi-isocyanate cross-linking agent, optionally dispersed in a fugitive organic solvent therefor. The method comprises the steps of: (a) forming an atomizing gas flow which comprises an intimate mixture of a carrier gas bearing a catalytic amount of a vaporous tertiary amine; (b) atomizing said liquid coating composition with said vaporous catalytic amine-bearing atomizing carrier gas flow; and (c) directing said atomizate of step (b) onto said substrate to form said applied film. t |
