Summary:PROBLEM TO BE SOLVED: To provide a process of forming an epoxy-imidazole catalyst that can impart an excellent shelf life and improved coating performance, such as hot water resistance, cathodic disbonding resistance, adhesion and low-temperature curability, when used as a curing catalyst in powder coating compositions.SOLUTION: A process of forming a solid epoxy-imidazole catalyst not containing residual solvent includes contacting an imidazole, an amine, and one or more epoxy resins in the absence of solvent.
