PROCESS FOR PREPARING AN ELECTROCOATING COMPOSITION COMPRISING A SOLID PIGMENT DISPERSION

摘要

The present invention is directed to a process for producing an aqueous cathodic electrocoating composition comprising A) mixing i) a powder comprising a dispersion of a pigment in a solid resin ii) a principal resin iii) a crosslinker and optionally iv) an additive selected from the group consisting of organic solvents, catalysts, wetting agents, conditioning agents, thickeners, rheology control agents, antioxidants, surfactants, leveling agents and mixtures thereof B) salting with an acid and C) dispersing in deionized water.
