Thin coating film comprising fluorine-containing polymer and method of forming same

   
   

To provide the method of forming the thin coating film of fluorine-containing polymer having heat resistance and non-sticking property by adhering directly to a substrate without lowering characteristics such as reflection and light transmission which the substrate has. The thin coating film is a film which comprises a continuous layer of fluorine-containing polymer formed by adhering directly to the substrate and has a thickness of less than 3 .mu.m, wherein the fluorine-containing polymer in the coating film has a hydrophilic functional group and a crystalline melting point of not less than 200.degree. C.

Para fornecer o método de dar forma à película revestindo fina do polímero fluorine-containing que tem a resistência de calor e quefura a propriedade aderindo diretamente a uma carcaça sem abaixar características tais como a reflexão e a transmissão clara que a carcaça tem. A película revestindo fina é uma película que compreenda uma camada contínua do polímero fluorine-containing dada forma aderindo diretamente à carcaça e tenha uma espessura menos do mu.m de 3, wherein o polímero fluorine-containing na película revestindo tem um grupo funcional hydrophilic e um ponto de derretimento cristalino de não mais menos do que 200.degree. C.
