Title:
FLUORINE-CONTAINING ELASTIC COPOLYMER COMPOSITION, PAINT, AND PAINTED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2019/073934
Kind Code:
A1
Abstract:
Provided is a fluorine-containing elastic copolymer composition that has excellent dissolvability of a fluorine-containing elastic copolymer into a solvent and whereby the solvent is easily removed and the solvent is readily obtainable. The fluorine-containing elastic copolymer composition includes: a fluorine-containing elastic copolymer having a unit based on tetrafluorethylene and a unit based on CF2=CFORf1 (Rf1 being a C1–10 perfluroalkyl group); and a fluorine-containing solvent having a perfluorohydrocarbon group. The highest number of carbon atoms for the perfluorohydrocarbon group in the fluorine-containing solvent is 3–7; the boiling point for the fluorine-containing solvent is 50–160ºC; and the fluorine atom content in the fluorine-containing solvent is 69%–80% by mass (calculated as fluorine atom content (% by mass) = (19 × (number of fluorine atoms in fluorine-containing solvent)/(molecular weight of fluorine-containing solvent)) × 100.)
