Abstract
The invention is a method for improving the flow of particulate lacquer powders when the lacquer powders are coated on a substrate and the substrate heated to fuse the lacquer particles to provide a finished lacquer surface on the substrate. The flow control agent is an oxazine, oxazoline, oligoxazine or oligoxazoline and salts of the compounds with protonic acids. The flow control agents when included in power lacquer formulations improve the flow of the lacquer when the powder lacquer coated substrate is heated to fuse the coating.
