The paper with the title “Monitor the stability of an epoxy acrylic based lacquer during storage” authored by Ms. E. Spiropoulou, Dr. D. Voulgaris and Mr. M. Mariglis from the Surface Science and Coatings Department of ELKEME S.A was presented as oral presentation in the Thermosets 2015 Conference, 16-18 September 2015, Berlin, Germany. This paper focuses on monitoring the impact of storage conditions on the stability of a lacquer by using reliable techniques. The examined lacquer developed strong yellowness, visually observed, during storage. A color comparator device and absorbance measurements by using a photo-meter were employed to characterize the liquid lacquer during time. A Differential Scanning Calorimeter (DSC) was used to determine the glass transition temperature of the cured lacquer on aluminium. The data collected revealed that these techniques are suitable for aging studies of lacquers.
