Abstract
A variety of methodology which are supposed to accelerate and/or simulate the effects of time and environment, weathering, on organic coatings degradation are under development since long time. Taking into account that no test can duplicate all of the variables associated with a coatings environment, two modern accelerated tests were carried out and their investigation capabilities were compared: the Norwegian Norsok M 501 and the thermal cycling in electrolyte immersion. The first test highlighted the adhesion performances of coatings and the importance of the zinc-rich primers on the scratch protection. The thermal cycling test has lead to a very rapid loss of film properties. Electrochemical impedance measurements associated to this test have shown the relative importance of electrical resistance and capacitance in predicting corrosion protective performance in presence of very thick coatings.
