Cure characterization of epoxy and polyester clear powder coatings
Melting, flow, gel point and cure completions are the principal stages in film formation of powder coatings and are determining both the paint aesthetic and protective properties [9]. In powder paint technology, time-consuming and empirical work is often necessary to find the optimum temperature program for the curing process.
