Abstract
A powder coating composition particularly useful in coating unprimed substrates which comprises a particulate form of a carboxylated polyolefin. The carboxylated polyolefin is prepared by reacting a polyolefin with an unsaturated dicarboxylic acid component. The carboxylated polyolefin has a saponification number of about 2 to about 12. The carboxylated polyolefin also has either a melt flow of from about 15 to about 175 g./10 minutes at 230.degree.C. or a melt index of 5 to 75 at 190.degree.C. The particulate form has a particle size of less than 20 mesh.
