Abstract
A metering rod type coating applicator is provided with a metering rod having its peripheral surfaced texture to a texture in a range of Ra 0.06 to Ra 1.6 to improve the application of coating to a moving surface and permit uniform coating application using higher solids content coatings and/or lower coat weights. Preferably, the rod will be rotated at a speed significantly higher than that conventionally used and preferably with a peripheral velocity in the range of about 15 to 20 m/min.
