Abstract

A thermosetting polymer material capable of being used in powder coatings. The thermosetting polymer material includes at least one hydroxyl functional aliphatic polycarbonates that is formulated and crosslinked with isocyanates to yield a thermoset organic coating material. These materials provide improved weatherability as compared to prior art powder coating materials while also being less expensive than prior art materials utilizing fluorinated polymers.
