Title:
FLUORORESIN-CONTAINING SOLUTION, PROCESS FOR PRODUCING FLUORORESIN-CONTAINING SOLUTION, COATING COMPOSITION, AND COATED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2017/122701
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a fluororesin-containing solution which has excellent storage stability and can form coating films excellent in terms of glossiness immediately after film formation. Furthermore, the present invention addresses the problem of providing a process for producing the fluororesin-containing solution, a coating composition, and a coated article.
The fluororesin-containing solution of the present invention comprises: a fluororesin comprising a fluoropolymer that comprises units based on chlorotrifluoroethylene; an aminated compound; and an organic solvent. The fluororesin-containing solution has a chlorine ion concentration, as determined by the following chlorine ion concentration measurement method, of 50 mass ppm or less. Chlorine ion concentration measurement method: the fluororesin-containing solution is mixed with xylene to prepare a sample solution; the obtained sample solution is mixed with water; the resultant mixture is subjected to phase separation into a xylene phase and an aqueous phase, and the aqueous phase is recovered; and the chlorine ion concentration in the recovered water is determined by ion chromatography.
