摘要

A powder coating composition is provided to ensure non-glossiness, beautiful appearance, excellent corrosion resistance and water resistance and to be near-infrared curable. A powder coating composition comprises base resin 100.0 parts by weight; triglycidylisocyanurate 1~15 parts by weight as a hardener; a hardener 1~10 parts by weight having an acid functional group; and filler 10~40 parts by weight. The base resin comprises polyester resin 10~30 weight% including a terephthalic acid; polyester resin 30~60 weight% including an isophtalic acid; acrylic resin 1~20 weight% having a glycidyl functional group; and a mixture 5~30 weight% of polyester resin(1) containing a carboxyl group having viscosity of 2,500~4,500 cps and polyester resin(2) a carboxyl group having viscosity of 5,500~8,000 cps.
