    摘要: To provide the thermosetting powder coating composition which comprises a fluorine-containing copolymer having crosslinkable functional group and a curing agent, in which the fluorine-containing copolymer has a fluoroolefin unit, has a fluorine content of not less than 10% by weight and is not dissolved in tetrahydrofuran substantially. A coating line can be shared with other powder coating composition because even when the composition mixes to other powder coating composition, it causes no coating defects, and yet a coated article having a coating film excellent in physical properties can be provided.
