ABSTRACT:
A process for drying a liquid electrodeposited coating composition applied to a metal substrate is provided. Infrared radiation and warm air are applied simultaneously to the electrodeposited coating composition for a period of at least about 1 minute, the velocity of the air at the surface of the electrodeposited coating composition being less than about 4 meters per second. The temperature of the metal substrate is increased at a rate ranging from about 0.25.degree. C. per second to about 2.degree. C. per second to achieve a peak metal temperature of the substrate ranging from about 35.degree. C. to about 140.degree. C. Infrared radiation and hot air are applied simultaneously to the electrodeposited coating composition for a period of at least about 2 minutes, during which the temperature of the metal substrate is increased at a rate ranging from about 0.2.degree. C. per second to about 1.5.degree. C. per second to achieve a peak metal temperature ranging from about 160.degree. C. to about 215.degree. C., such that a dried electrodeposited coating is formed upon the surface of the metal substrate.
