Document Type and Number:
WIPO Patent Application WO/2020/241121
Kind Code:
A1
Abstract:
The present invention provides a primer for ETFE coating materials, which provides a primer film that enables the achievement of excellent adhesion between an object to be coated and an ETFE coating film. A primer for ETFE coating materials, which contains ethylene/tetrafluoroethylene copolymer (ETFE) particles, a heat-resistant resin and a nonionic surfactant, wherein: the ETFE particles have an average particle diameter of from 5.0 μm to 50 μm; the heat-resistant resin is composed of at least one resin that is selected from the group consisting of polyamide imide resins, polyether sulfone resins and polyimide resins; the solid content mass ratio of the ETFE particles to the heat-resistant resin is from 60:40 to 90:10; and the nonionic surfactant is a polyoxyethylene alkyl ether surfactant.
