Abstract:
The invention relates to a method for producing a pigment paste and an electrocoat containing the paste, the past being made by mixing solid pigment particles with a grind resin in the presence of water and/or an organic liquid, wherein the grind resin includes a dispersion of core-shell particles in an epoxide prepolymer which is liquid at 20° C. and the core-shell particles have a silicone core and a polymer shell.
