ABSTRACT:
Aluminum pigments are produced by wet milling in the presence of water, employing a coupling agent to allow miscibility of water in the milling slurry, in order to compensate for inefficient aeration of commercial ball mills. Hydrogen peroxide may be employed to the same purpose without a coupling agent. This process assures the production of high quality leafing aluminum pigments.
