Abstract
A powder coating composition according to the present invention is used in the coating of a molded product having wrinkles, cavities and the like in its surface. The powder coating composition contains a single film forming resin or a plurality of film forming resins having a melt viscosity of 60 Pa·s/165° C. or less and selected from the group consisting of an epoxy resin, a polyester resin and an acrylic resin, and at least two fillers having different particle size in a range of 3 to 100 &mgr;m. Thus, the powder coating composition is applied directly onto a to-be-coated-surface without need for a pretreatment such as the sanding of the surface and the filling of the surface by a patty. Therefore, a molding failure of the surface can be hidden satisfactorily to form a coated surface excellent in design. Moreover, an organic solvent or the like is not used, and hence, the air pollution is prevented, and the danger of a fire is reduced remarkably.
