PROBLEM TO BE SOLVED: To provide an epoxy resin powder coating whose after-cured coating film has both good heat resistance and also good adhesion after humidification, while retaining basic properties of an epoxy resin powder coating. SOLUTION: The epoxy resin powder coating is characterized by containing (A) an epoxy resin, (B) a curing agent, (C) an inorganic filler and (D) a silane coupling agent. Preferably, the curing agent (B) is an acid anhydride-based curing agent and the silane coupling agent (D) is an aminosilane coupling agent. COPYRIGHT: (C)2008,JPO&INPIT
