Disclosed is a heat-curable powder coating composition whose crosslinked films exhibit an enhanced hydrophobicity without detracting mechanical properties. The composition comprises a binder and a compound having a polyhedral oligomeric silicon-oxygen cluster unit of the formula: [(R a X b SiO1.5)m(R c X d SiO)n(R e X f Si2O2.5)o(R g X h Si2O2)p] wherein a, b, c = 0-1; d = 1-2; e, f, g = 0-3; h = 1-4; m + n + o + p >= 4; a + b = 1; c + d = 2; e + f = 3; g + h = 4; R is hydrocarbon group or the like; and X is alkoxy group or the like.
