NON-AQUEOUS DISPERSION LIQUID, AND METHOD FOR PRODUCING LAMINATE

Document Type and Number:

WIPO Patent Application WO/2021/075504

Kind Code:

A1

Abstract:

[Problem] To provide: a non-aqueous dispersion liquid which has good dispersion stability, and from which a molded product having excellent processability can be formed; and a method for producing a laminate using such a non-aqueous dispersion liquid. [Solution] A non-aqueous dispersion liquid according to the present invention includes: a first powder which is a polymer having a unit based on tetrafluoroethylene and a unit based on perfluoro(alkyl vinyl ether); a second powder which is polytetrafluoroethylene having a number average molecular weight of 10,000-200,000 as calculated by a predetermined formula; a nonionic surfactant; and a non-aqueous solvent. In addition, the percentage of the polytetrafluoroethylene with respect to the sum of the polymer and the polytetrafluoroethylene is preferably at most 50 mass%.
