Abstract

PURPOSE: To form the superior captioned film of desired electrical characteristics through simple pretreatment and instantaneous high-temperature heating by forming a viscous viscous resin film on the surface to be adhered and coating fluoroplastic powder on said film while this film is assuming liquid form.
CONSTITUTION: When staining material deposits on the outside wall 2a of the insulation case 2 of an electrical apparatus used in a polluting environment, e.g., a vacuum breaker 1, flashover occurs between metals 3 owing to the decrease in the insulation of the outside wall 2a. This necessitates forming material of good water repellency on the outside wall 2a. Thereupon, first the outside wall 2a is degreased with aceton θ, and after the perfect evaporation of acetone, the liquid-form composition of alicyclic epoxy resin is coated on the outside wall. While this is assuming liquid form, fluoroplastic powder is sprayed to the entire part of the outside wall. Such breaker 1 is put in an oven and is heated to gel the liquid-form composition. After this, the fluoroplastic is instantaneously melted by a suitably temperature- controlled burner while its flame is being moved, whereby it is crystallized and set in the same manner as the resin film.
