Abstract
Method and apparatus for forming a coating material, and for depositing the material onto the surface of an article or a substrate. The apparatus includes a tank within which the coating composition is formed together with a residual amount of gas. The tank and the internal support members are electrically segregated from a perforated container with reactant material held on the internal support to avoid the formation of gas bubbles on the surfaces of the tank and support which are immersed into the coating composition.
