Document Type and Number:
Japanese Patent JP7445146
Kind Code:
B2
Abstract:
Provided is a liquid coating composition which is suitable as a primer of a fluororesin layer and can achieve high adhesiveness. This liquid coating composition comprises an amide group-containing polymer compound (A) which has an amide group or will have an amide group, polyphenylene sulfide (B), and a perfluoro-based fluororesin (C), and is characterized in that: the amide group-containing polymer compound (A) is an amide group-containing polymer (a1) having an amide group and an aromatic ring and/or an amide group-containing polymer precursor (a2) which is changed into the amide group-containing polymer (a1) in a firing step when a film is formed from the liquid coating composition; the content of the polyphenylene sulfide (B) is 1-50 mass% with respect to the total amount of the amide group-containing polymer compound (A) and the polyphenylene sulfide (B); the perfluoro-based fluororesin (C) contains 85.0-99.5 mol% of tetrafluoroethylene and has a melt flow rate (MFR) in the range of 5-30 (g/10 min); and the content of the perfluoro-based fluororesin (C) is 50.0-95.0 mass% with respect to the total amount of the amide group-containing polymer compound (A), the polyphenylene sulfide (B), and the perfluoro-based fluororesin (C).
