Abstract: Surface-modified conductive pigment obtainable by partial coating of a conductive pigment with an organic modifying agent. The modifying agent is an organometallic compound of the elements silicon, tin, titanium, zirconium or aluminum. The pigment is prepared by dispersing a conductive pigment, subsequently adding the modifying agent, if appropriate as a mixture with a solvent, to the pigment dispersion, and in particular in an amount such that the powder electrical conductance of the partly coated conductive pigment is in the range between 80% of the starting value and 10−7 S, removing the solvent present, if appropriate, with further agitation and heating of the pigment to 100° C. and finally drying the partly coated pigment.

Abstract: A process for producing powder coating materials comprising lustre pigment comprises starting materials consisting of customary powder coating components and one or more lustre pigments. The starting materials are first introduced into the filling chamber of a first vessel which has a mixing element and is provided, if desired, with a thermostat. Subsequently, a supercritical fluid is admitted to the filling chamber, and finally the starting materials are mixed in the presence of the supercritical fluid. The mixture of the customary powder coating components, one or more lustre pigments and the supercritical fluid is transferred by a distributor into a second vessel. The distributor has a plurality of nozzles with an aperture diameter of from 0.025 cm to 2.5 cm. During transfer, the second vessel is maintained at an internal pressure of from 0 bar to 350 bar and at a temperature of from −85° C. to 200° C.
