Meltable fluororesin primer

Abstract

A meltable fluororesin primer including a tetrafluoroethylene/hexafluoropropylene copolymer (FEP) particles, a heat-resistant resin, a nonionic surfactant, an acetylenic diol-based surfactant and water, wherein: the FEP particles have an average particle size of 10 to 60 μm; the heat-resistant resin is selected from polyamideimide resins, polyethersulfone resins and polyimide resins; the solid content mass ratio between the FEP particles and the heat-resistant resin is 50:50 to 95:5; the nonionic surfactant is a polyoxyethylene alkyl ether surfactant; and the meltable fluororesin primer contains 10 to 60% by mass of water based on the meltable fluororesin primer. Also disclosed is a primer film formed from the meltable fluororesin primer, a laminate including a film containing a meltable perfluoropolymer provided on the primer film, and a coated article including the laminate.
