process for preparing an acrylic powder coating resin system, process for preparing powder coating composition, and coating on a metallic substrate

摘要

The present invention is a process for preparing an acrylic powder coating resin system. It includes the polymerization of at least one acrylic monomer in a non-aqueous solvent in the presence of a hydrophobic submicron particle and an initiator, as well as coating compositions. powders prepared from the acrylic powder coating resin system.
