摘要：
A powder coating composition comprising a homopolymer or copolymer of polyvinylidene fluoride having a melt flow index of 10 to 300 grams per ten minutes, determined in accordance with ASTM D 1238, Condition J and 5 to 50 weight percent of a glass having a grain size of 1 to 300 .mu.m; an improvement in a method of coating a metal or inorganic oxidic surface wherein a powder coating composition containing polyvinylidene fluoride is applied to such surface and fused thereon, the improvement residing in employing as the powder coating composition one containing 5 to 50 weight percent glass, based upon the weight of the polyvinylidene fluoride polymer; a coated object having a metallic or inorganic oxidic surface which is coated with a polyvinylidene fluoride homopolymer or copolymer which coating contains 5 to 50 weight percent, based upon the weight of the polyvinylidene fluoride, of glass particles, especially glass particles of a grain size of 1 to 300 .mu.m.
