ABSTRACT:
A wire coating powder is prepared by first formulating a solventless, aromatic polyester-amide-imide which is the reaction product of an aromatic diamine, an aromatic compound consisting of trimellitic anhydride, acid, or acid halide, and about 35 to about 100 mole % in excess of the stoichiometric amount needed to react with said aromatic compound of polyol.
A coating powder is prepared by hot melt mixing, cooling, and grinding a mixture of the polyester-amide-imide with straight polyester and a reactive solid or liquid aromatic monomer or prepolymer.
