摘要
An apparatus and method for the spray application of solvent-thinned coating compositions whereby optimum coverage of a substrate with a liquid film is consistently achieved without incurring sagging, run-off or surface irregularities, such as orange peeling, in spite of wide fluctuations in the temperature and/or humidity of the surrounding atmospheric environment. In accordance with the invention, a shroud is provided which is disposed in encompassing relationship around the spray nozzle to which air is supplied at a controlled temperature and/or humidity which envelopes and becomes entrained in the spray forming a controlled localized atmosphere and achieving a controlled vaporization of solvent from the liquid droplets during the course of their travel from the nozzle to the surface of the substrate being coated.
