A thermosetting powder coating composition comprising a fluorocopolymer having cross-linkable functional groups and a hardener, characterized in that the fluorocopolymer contains perfluoroolefin units, has a fluorine content of 10 wt.% or higher, and is substantially insoluble in tetrahydrofuran. The coating composition has the following advantages. Even when the composition mingles with other resin powder coatings, it causes no coating defects in the coating films formed from those powder coatings. The composition can hence be used in the same coating line as other powder coating compositions. Furthermore, the composition can give a coated object excellent in coating film properties. |
