Diffusion-controlled staining and degradation of organic coatings

摘要

Staining as well as chemical degradation of organic coatings is frequently induced by diffusion of aqueous and/or nonaequeous transport media into the coating. This process is followed by softening of the polymer film and a further transport of critical molecules into the polymer. In the poster complementary techniques like EIS, colourimetry, swelling and microhardness measurements are employed to analyse these transport processes in thermoset coatings.
