Abstract

In the electrostatic spraying on metal substrates of mixtures of different inorganic powders which differ in density, particle size and electrical resistance, the improvement which comprises first forming uniform agglomerates as the different powders, and then spraying the uniform agglomerates. This prevents color variation due to separation of different powders.
