A novel aqueous powder coating dispersion (powder slurry) is preparable by n (1) emulsifying at least one binder in the liquid state in a toothed-ring dispersing apparatus in an aqueous medium, n (2) causing the resulting emulsion to cool, so that a suspension is formed, and n (3) filtering the suspension, n wherein the toothed-ring dispersing apparatus comprises at least one cylindrical arrangement of at least two comminutor rings (stator and rotor) which are seated on holders, are in mutual embrace, and are rotatable in opposite directions relative to one another, the working gap produced by the relative movement between stator and rotor having walls which extend nonparallelwise with respect to one another. |
