To provide a powder coating composition which comprises 100 parts by weight of fluorine-containing resin and 1 to 40 parts by weight of tetrafunctional or trifunctional silicate compound or a condensation product thereof, has a function of removing electrostatic charge and gives a coating film having a high hardness and stain-proof property.

Fluorine-containing resin powder coating composition

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.

Thermosetting powder coating composition

To provide a thermosetting powder coating composition which comprises a powder of a composite resin comprising a vinylidene fluoride polymer having crosslinkable functional group and a methyl methacrylate polymer and having a melt flow rate of 1 to 1,000 g/10 min when measured at 130&deg; C. at a load of 2.1 kg. The coating composition has advantages that the preparation thereof is easy because pulverization can be carried out at room temperature as well as at low temperatures, the composite resin has excellent compatibility with various curing agents and the composition gives a coating film having excellent properties.
