<p>A process for producing a dry coating layer over a substrate is provided. The process can comprise irradiating a radiation curable wet coating layer applied over the substrate with a high power mobile radiation device at a predetermined linear velocity along the surface of the substrate and at a predetermined curing distance. The mobile radiation device can produce radiation having peak radiation wavelength in a range of from 250 nm to 450 nm and can have a peak irradiation power in a range of from 0.5 W/cm2 to 10 W/cm2. The wet coating layer can be cured within a few seconds to a few minutes. The cured dry coating layer is free from curing defects. The process and the system disclosed herein can be used for vehicle coating refinish and repairs, especially for collision and cosmetic repairs of automobiles.</p> |
