A primer for an ETFE coating material containing: ethylene/tetrafluoroethylene copolymer (ETFE) particles; a heat-resistant resin; and a nonionic surfactant. The ETFE particles have an average particle size of 5.0 to 50 &#x3bc;m. The heat-resistant resin includes at least one selected from polyamide-imide resin, polyethersulfone resin, and polyimide resin. The ETFE particles and the heat-resistant resin have a solid content ratio by mass of 60:40 to 90:10. The nonionic surfactant includes a polyoxyethylene alkyl ether surfactant. Also disclosed is a primer film obtained from the primer for an ETFE coating material as well as a coated article.

Primer for ethylene/tetrafluoroethylene copolymer coating materials

A powder coating material including a main material resin containing an epoxy resin; a phosphorus flame retarder; and at least one inorganic particulate substance selected from metal hydroxides and hydrous metal compounds. The inorganic particulate substance has an average particle size of 0.01 to 9 &#x3bc;m. The inorganic particulate substance is present in an amount of 80 to 200 parts by mass relative to 100 parts by mass of the main material resin.
