Abstract
High molecular weight polyaniline may provide corrosion protection to cold rolled steel exposed to the severe corrosion environment. However, it was shown in the past that coatings of polyaniline exhibited rather poor adhesion to steel substrates. We have shown that epoxy cured amino terminated aniline trimers offered excellent corrosion protection and showed a better anticorrosion performance than the conventional polyaniline coatings. Such a better performance might be attributed to the possibility that the oligomers could have better 'adhesion' to (or more intimate contact and interactions with) the surface of metal substrate. In this paper, we present the results of a comparative study of variations in molar ratio of epoxy to amino terminated compounds such as the aniline trimer and 1,4-phenylenediamine cured at two different temperatures and their effects on adhesion properties over cold rolled steel (CRS) panels after 1000 hours of salt spray.
