Amorphous fluorine-containing resin composition and a manufacturing method of thin films

Abstract

[Object of this Invention] To provide the amorphous fluorine-containing resin composition that has superior film-forming ability, and has a small impact on the global environment due to its very small global warming potential, and can fully satisfy the requirement from the perspective of the environmental protection of the earth; and to provide the article that contains the coating that is formed from the thin films that are made from this amorphous fluorine-containing resin. composition.
