Document Type and Number:
Japanese Patent JP2913377
Kind Code:
B2
Abstract:
A powder coating is provided, comprising a particulate material having a particle diameter satisfying the following requirements: (a) the volume 50 % diameter be from 7 to 15 mu m; (b) the proportion by volume of the particles having a particle diameter of not less than 20 mu m and those having a particle diameter of not less than 30 mu m in the particulate material be not more than 10 % and 0 %, respectively; and (c) the proportion by population of the particles having a particle diameter of not more than 5 mu m in the particulate material be not more than 50 %, the particulate material having an external additive attached to the surface thereof, the percent coverage by the external additive determined by the following equation described in the specification being from 30 to 100 %. The powder coating can provide a film having a reduced thickness with an improved leveling and hence make it possible to improve the working efficiency and re-use the fractions of the powder coating recycled from the coating process, realizing the reduction of the total cost.
