Abstract
It is an object of the present invention to provide a powder coating which is excellent in processibility to attain the desired coat surface smoothness and can give coats excellent in chemical resistance and free from cracking due to chemicals or temperature shocks. The present invention provides a powder coating containing a tetrafluoroethylene-based copolymer wherein the tetrafluoroethylene-based copolymer is a copolymer of 5 to 25% by mass of hexafluoropropylene, 0.01 to 5% by mass of perfluoro (vinyl ether), and tetrafluoroethylene and has a melt flow rate of 1 to 30 g/10 minutes.
