Abstract
Organic or inorganic particulate solid substances are coated with a polymeric material by dispersing the particulate solids, the surfaces of which have been treated so as to be compatible with the polymer coating, in a solution containing the polymer dissolved in a water-immiscible solvent, slowly introducing into the dispersion an aqueous solution of a hydrophilic protective colloid, thus producing an emulsifying liquid medium, and removing therefrom the solvent, to finally obtain polymer coated solid particles. The polymer-coated powder thus obtained is useful for application to various substrates by fluidized bed coating, electrostatic spraying, or electrophoretic deposition, followed by sintering to form films.
