Coating powders, methods of manufacture thereof, and articles formed therefrom

摘要

Coating powders comprising a solid, particulate film-forming composition and encapsulated catalysts provide stable one-part compositions. The film-forming composition can be a low-temperature cure coating powder such as a carboxylic acid functional polymer/epoxy curative coating powder or a polyester resin/epoxy curative coating powder. The encapsulated catalyst can be a catalyst suitable for the coating powder used such as a substituted imidazole.
