Title: POWDER COATING COMPOSITION, PROCESS FOR PRODUCING POWDER COATING COMPOSITION, AND COATED ARTICLE
Abstract:
The present invention addresses the problem of providing: a powder coating composition capable of forming coating films excellent in terms of surface smoothness, thickness evenness, and processability; a process for producing the powder coating composition; and a coated article obtained using the powder coating composition. The powder coating composition of the present invention comprises poly(vinylidene fluoride), which is a homopolymer of vinylidene fluoride, a nonfluorinated resin containing no units based on a monomer having a crosslinkable functional group, and at least one pigment selected from among glitter pigments, rust-preventive pigments, color pigments, and loading pigments, the content of the pigment being 10-100 parts by mass per 100 parts by mass of the sum of the poly(vinylidene fluoride) and the nonfluorinated resin. The powder coating composition has a specific surface area of 0.1-0.8 m2/g and an angle of repose of 50 degrees or less.
