Abstract:

Highlights•Thermal stability of durable and superdurable powder coatings was investigated.•Activation energies were determined by applying Kissinger equation on TGA data.•Activation energy is about 25 kJ mol−1 higher for the superdurable sample.•Comparable results were obtained from colorimetric experiments on aged samples.
