ABSTRACT:
Polymeric powder coating compositions featuring improved physical properties including improved impact strength, improved adhesivity and other properties is provided by a polymeric powder coating composition which comprises: (a) polymeric powder coating resin, (b) at least one low molecular weight ethylene copolymer having a degree of saponification of at least 25%, (c) a further constituent selected from the group consisting of catalyzing agents, flow control agents, coloring agents, fillers, processing aids, wherein the weight ratio of (b) to (a) is preferably in the range of 0.01%-20% to 99.99%-80%. The powder coating composition may be applied to articles using conventional techniques. Processes for producing the polymeric powder coating compostiions, and articles comprising the same are also disclosed.
