Cure characterization of epoxy and polyester clear powder coatings using Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Thermal Analysis (DMTA)

The thermal behaviour of an epoxy/polyester hybrid and a polyester clear powder coatings was evaluated by means of Differential Scanning Calorimetry (DSC). The effect of curing temperature on the coating glass transition temperature (Tg) was also studied using a Dynamic Thermo-Mechanical Analyser (DMTA). The DSC method allows the explanation of powder coating systems. The procedures established enable to clearly identify the periods of melting, …
