Electrochemical impedance spectroscopy (EIS) - a high potential method?

 
The testing of anti-corrosive coatings is a highly time and ressources consuming procedure. While in the past the testing time for system screenings was already significantly reduced from years to months respectively weeks changing from natural weathering to different forms of accelerated testing, like salt spray testing and humidity testing, the electrochemical impedance spectroscopy is said to have a high potential to reduce a single test to hours. This would enable technologists and scientists to really set-up high-throughput screening in the fields of anti-corrosive coatings. The current talk will present results of different paint systems varying binders, substrates, anti-corrosive pigments etc. and comparing salt spray test results with the test results of much faster electrochemical impedance spectroscopy from the standpoint of an anti-corrosive pigment manufacturer.
