場合耐久性が良くない。Conventional methods for forming fluororesin coatings include using fine powder of fluororesin with additives such as colloidal silica.
Using a composition dispersed in water containing a surfactant, the composition is applied, dried to temporarily adhere to the object, and then heated to 320°C to 420'C to thermally melt the fluororesin. to form a film through interparticle fusion using A method is known in which a coating composition dispersed in an organic solvent solution or an aqueous dispersion is used to form a fluororesin coating by utilizing the film-forming action of organic plastics. However, the film obtained from the former is heat-softening, and the film obtained from the latter has low hardness and poor durability when used for iron bases, cooking utensils, etc.

び被塗装物との密着性が低下する。The ratio of low melting point glass and fluororesin in the composition is 10 for the former.
5 to 120 parts by weight of the latter is suitable. If the proportion of fluororesin is small, the mold releasability, which is a characteristic of fluororesin, will be low, and if the proportion of fluororesin is too large, the hardness and adhesion to the object to be coated will decrease.
