Abstract

The interface between paint and chromate-coated steel sheet in the paint-coated steel sheet system were investigated using ATR IR spectroscopy technique to elucidate interactions between the paint and steel sheet. The paint composed of a mixture of alkyd resin and melamine resin, and the steel sheet modified with chromic acid were used as specimens for the experiments. In order to observe IR spectra at the paint/ chromate-coated steel sheet interface, the paint layer coated on the chromate-coated steel sheets was sandpapered to make thin layer of less than 1 μm thickness, which was smaller than the penetration length of Evanescent wave. The paint at the paint/ chromate-coated steel sheet interface showed different IR spectrum from the bulk of the paint layer. C=O absorption (1722 cm<SUP>-1</SUP>) in the alkyd resin showed weak intensity, and a new absorption at 1600 cm<SUP>-1</SUP> appeared. Such changes in the IR spectrum indicate that C=O groups in alkyd resin could interact with the steel sheet to contribute to adhesion of the paint/chromate-coated steel sheet adhesive joints.
