Polymer coatings on steel substrates were analyzed by reflectance/absorbance infrared spectroscopy. Initial studies were performed ex‐situ on samples which had been cured at a variety of temperatures on two different substrates. Further studies were done in‐situ under both air and nitrogen atmospheres. The two substrates studied were untreated cold‐rolled steel and cold‐rolled steel with a conversion coating of zinc phosphate. Changes in the spectra of the phosphate conversion layer correlated well with anti‐corrosion properties. Mechanisms of degradation and cure could be determined from the in‐situ studies (1).
