Method of applying a coating powder to a substrate

摘要

An atomized fluid, such as a mist of water, is applied to a preheated substrate, such as wood, a wood product, paper, or ceramic just prior to or contemporaneously with electrostatically applying a coating powder to the substrate. The atomized fluid is absorbed or adsorbed by the substrate so as to enhance the charge-carrying capacity of the substrate to an extent necessary to promote efficient electrostatic application of the coating powder to the substrate.
