Abstract:
A method of providing a smooth paint coat of an organic polymeric paint composition on a surface of a moving substrate, comprising establishing a quantity of the paint composition, in a high solids form at a temperature such that it is spreadable, in a nip defined by the substrate surface and a smoothing roll to enable paint from the established quantity to pass through the nip as a paint layer on the substrate surface, wherein the smoothing roll has a surface roughness coefficient (Ra) of no more than 1.5, and wherein the maximum surface speed of the smoothing roll expressed as a percentage of the substrate speed bears a linear relationship to the substrate speed, such that the surface speed of the smoothing roll is no more than 1.2 percent of the substrate speed at an exemplary low substrate speed of 15 meters per minute and no more than 12 percent of the substrate speed at an exemplary substrate speed of 150 meters per minute.
