PURPOSE: A powder-coated composition is provided to improve heat resistance and corrosion resistance, to minimize the loss of flexural resistance and adhesion to resins, thereby providing high glass transition temperature and excellent flexural resistance. CONSTITUTION: A powder-coated composition comprises 10-80 weight% of an epoxy resin selected from a bisphenol A epoxy resin, novolak modified epoxy resin, isocyanate-modified epoxy resin, and cresol novolak epoxy resin; 1-50 weight% of a polyol derivative; 0.1-30 weight% of a curing agent; 0.01-1.0 weight% of a curing aid; 1-50 weight% of an inorganic filler; and 1-50weight% of a color pigment. The polyol derivative is represented by chemical formula 1. In chemical formula 1, each of R1 and R2 is a saturated or unsaturated hydrocarbon group. The saturated or unsaturated hydrocarbon group can be coupled with a substituent or form a ring. |
