    摘要: A powder coating composition includes one or more crystalline substances the lowest melting point of which is Mp and one or more non-crystalline substances the lowest glass transition point of which is Tg and is lower than Mp, wherein the crystalline and non-crystalline substances are selected from epoxy resins and curing agents and bonded to each other. The bonding is effected by maintaining a powdery mixture containing the crystalline and non-crystalline substances at a temperature higher than Tg but lower than Mp and the softening point of any of the the non-crystalline substances, optionally under a pressure, and cooling and pulverizing the resulting mixture.
