Epoxy resin powder coating composition

摘要

An epoxy resin powder coating composition is described, comprising an epoxy resin and at least a hardener and a filler compounded thereto, wherein the filler is a mixture of from 30 to 180 parts by weight of a needle-like glass powder having an average length of at least 40 mu m and an aspect ratio of at least 4:1 and at least 30 parts by weight of a granular inorganic filler having an average particle diameter of 1.0 mu m or less, both being based on 100 parts by weight of the epoxy resin. This powder coating composition can provide a coating exhibiting excellent impact resistance not only at room temperature but also at lower temperatures, and further having good flexibility. A steel member with the coating of the present powder coating composition has a high practical value.
