ABSTRACT:
A method for applying a coating composition to a substrate is disclosed. A rapid curing process is used to apply the coating composition. The method comprises the steps of forming a coating composition by combining, i) a base paint comprising nonvolatile constituents and a coalescing solvent, and ii) a carrier solvent, b) heating the substrate at a sufficient temperature to promote flashing of the carrier solvent; and c) applying the coating composition to the heated substrate, wherein the carrier solvent is flashed, resulting in a paint film relatively free of carrier solvent, whereby the paint film forms a cured coating on the substrate. The carrier solvent preferably is acetone.
