ABSTRACT:
Significant improvements in the coating characteristics of electrostatic fluidized beds are obtained by limiting the weight of the fines in the coating powder to certain maximum levels, e.g., no more than 10% by weight of minus 38 micrometer particles. The improvements include faster build rates, higher deposition weights, and deeper penetration into holes, slots or other cavities of the substrate.
