▎ 摘  要

NOVELTY - Powder coating composition comprises first hot-melt fluoro resin particles having an average particle diameter of 2-100 μ m in which a filler is dispersed in the particles, second hot-melt fluoro resin particles having an average particle diameter of 10-200 μ m, and charge controlling agent particles. USE - The powder coating composition is used in manufacturing coating film for cookware, such as frying pans, rice cookers, heat-resistant release trays in factory lines (such as a bread-baking process and the like), office equipment-related products, such as fixing rollers/belts/inkjet nozzles, and industrial equipment-related products at chemical plants, such as piping. ADVANTAGE - The composition has increased fluoro resin and properties of fluoro resin, such as releasability, slipping properties, chemical resistance, weather resistance, tack-free properties, water and oil repellency, and conductivity. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a coating film, which is manufactured from the powder coating composition, and the film has a thickness of 100 μ m or more.
