A study was conducted to analyze the root cause of the intercoat delamination failure of epoxy and epoxy and epoxy and urethane coating systems. The analyses were carried out using pH indicator paper and Fourier transform infrared (FTIR) spectroscopy to improve the performance of epoxy paints for marine and offshore structures. The presence of amine blush in the coating systems was confirmed by comparing the color of the saturated pH paper to the standard color chart provided in the container. FTIR measured the frequencies in which the sample absorbed the radiation to allow identification of its chemical characteristics. It was observed that the pH indicator paper test and ATR FTIR spectroscopy were used to analyze the main causes of coating failures in the case of the adhesion failure between epoxy and epoxy or urethane coatings.
