Abstract
—The interfacial reactions of galvanized steel with a poly(vinyl chloride) adhesive formulated with epoxy resin and dicyandiamide have been studied using X-ray photoelectron spectroscopy (XPS). The dicyandiamide was observed to segregate partially to the adhesive/substrate interface. A small amount of amine hydrochloride, evidently formed by reaction of dicyandiamide and HCI formed by dehydrochlorination of the poly(vinyl chloride), was observed near the adhesive/ galvanized steel interface. Dehydrochlorination of poly(vinyl chloride) appears to be enhanced in the adhesive/substrate interfacial region relative to the bulk, but less degradation was observed than for unmodified poly(vinyl chloride) formulations. In parallel studies on cold-rolled steel, neither thermal degradation nor amine hydrochloride formation was observed.Keywords
