Abstract
A spray coating process for application of water-dilutable paint systems which includes spraying a water-dilutable paint through a main nozzle which atomizes the paint and simultaneously therewith spraying at least one additional material from at least one lateral ancillary nozzle into and/or around the paint stream from the main nozzle. The additional material can be water to control the water content of the paint film, or it can be an additive such as a leveling aid for the paint. The spraying of the additional material into and around the paint stream while it is being projected to the surface to be painted causes the material to locate primarily at the surface of the atomized paint droplets.
