Abstract

The present disclosure describes cyclic carbonate-amine resin coating compositions including an amino functional silicon resin component, where the cyclic carbonate-amine resin coating displays improved oxidation resistance and durability. The coating compositions are isocyanate free and may be cured a low temperatures to provide a durable coating. In specific embodiments, the described coating compositions may be used as a mono-coat on a surface of an article, without any undercoating or primer layers.
