Title:
COATING COMPOSITION AND PRODUCTION METHOD FOR SAME, AND FORMATION METHOD FOR COATING FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2011/129032
Kind Code:
A1
Abstract:
Disclosed is a coating composition which can form a coating film through the application thereof, and which can be produced at relatively low temperatures. The disclosed coating composition contains a fluorine-containing copolymer which contains repeating units derived from ethylene and tetrafluoroethylene. Also disclosed is a production method for the coating composition, and a method for forming a fluorine-containing copolymer coating film which uses the composition and which can be formed at a relatively low temperature. The coating composition contains microparticles of a fluorine-containing copolymer (ETFE) having repeating units derived from ethylene and repeating units derived from tetrafluoroethylene, and a solvent wherein the ETFE can be dissolved at a temperature not greater than the melting point of the ETFE. The composition is characterised in that the ETFE microparticles are microparticles which have been precipitated from the solution formed by dissolving the ETFE in the abovementioned solvent, and are dispersed in said solvent.
