Estimating the term…
A uniform, thick film is formed by applying a powdered metal, alloy, sulfide of metal or glass each particle of which is coated with plastics 1-15% by weight, preferably the particle surfaces having been treated with an aliphatic acid or a silane-type surface-treating agent and the plastics including an organic peroxide, to a substrate by electrostatic powder spraying, fluidized bed coating, electrophoretic deposition, or by electrostatic fluidization, and fixing the layer thus provided on the substrate with heating to such extent that the plastic ingredient is fused or volatilized, to finally produce the desired film. The materials having such films fixed thereon have a wide application for interior building and glass-lining and as material of bearings.
A process of forming a uniform film at least 200.mu. thick on a substrate which comprises surface-treating an inorganic substance having a particle size range from 0.1 to 500 microns with a surface-treating agent to render its surface compatible with plastics, said surface-treating agent being selected from the group consisting of stearic acid, palmitic acid, gamma-methacryloxypropyltrimethoxy silane, gamma-glycidoxypropyltrimethoxy silane, and beta-ethyltrimethoxy silane, coating each surface-treated particles with plastic in an amount equal to 1 to 15% by weight of the particle, drying the coated particles, applying said dried coated particles to the substrate, and heating and fixing the layer thus provided on the substrate surface at a temperature between the melting point and the volatilizing point of the plastic.
