In the case of dispersion coating of polytrifluorochloroethylene, the film is formed by the fusion of coated particle during baking. The change of shape of the fused particle in baking was observed microscopically, and the mechanism of film-formation was disscused.
Adhesiveness of the film was also measured. it was, on an average, nearly equal to those of epoxy-resin coating and polyethylene flame sprayed coating, depending considerably upon the kind and pretreatment of the base metal.
Aluminum and steel pretreated by grid blasting seemed to be the best base metals to obtain strongly adhesive coatings. In the case of copper alloys, the adhesiveness was generally very low, but by plating chromium or nickle on the base, it was increased nearly as large as in the case of soft iron base.
