ABSTRACT:
An apparatus and method for evaporating a coating solvent from a coating on a substrate and for minimizing the formation of mottle. The coating is heated with a first drying gas at no higher than a first heat transfer rate. The first heat transfer rate is created by a first heat transfer coefficient and a first temperature difference between the first coating temperature and the first drying gas temperature. The first heat transfer rate causes maximum evaporation of the coating solvent yet insignificant formation of mottle when the coating is at the first coating thickness and the first coating viscosity.
