Abstract:
A thermosetting powder coating material includes powder particles that include a core which contains a thermosetting resin and a thermosetting agent having a blocked isocyanate group and a resin coating portion which contains a thermosetting resin having a glass transition temperature of equal to or higher than 45° C. and coats a surface of the core, and satisfy the followings (1) to (4): (1) a volume particle diameter distribution index GSDv of the powder particles is equal to or less than 1.50; (2) an average circularity of the powder particles is equal to or greater than 0.96; (3) a melting temperature of the powder particles measured according to a ½ method by using a flow tester is from 90° C. to 115° C.; and (4) an exothermic peak is within a range of from 80° C. to 150° C. in a differential scanning calorimetry measurement of the powder particles.
