The interfacial chemistry of a highly pigmented chlorinated rubber paint applied over aluminium, cold‐rolled and stainless steel, copper and zinc metallic substrates and poly(vinyl chloride) (PVC) polymer sheet have been studied using x‐ray photoelectron spectroscopy (XPS). The results obtained by XPS were compared with those of bond strength measurements. The XPS analyses reveal significant differences in the failure mode. The chlorinated rubber paint on the PVC polymer sheet displays the highest bond strength value and on the zinc the lowest. Chemical changes, suggesting dehydrochlorination of chlorinated rubber paint in the paint/metal interfacial region, were only observed on the metallic substrates. With the aluminium, stainless steel, copper and zinc substrates, the curing of the chlorinated rubber paint causes the formation of a highly hydrocarbon‐enriched interfacial paint surface. In contrast, the chlorinated rubber paint/PVC polymer sheet system shows no change in the interfacial surface composition. © 1998 John Wiley & Sons, Ltd.
