The corrosion of zinc metal by vapours from cured styrene-based polyester resins has been studied. The production of corrosive vapours has been found to be greatly influenced by the curing system. Peroxides of different types have been examined, some in the presence of accelerators. Resins cured by y-radiation, and by azodi-isobutyronitrile, showed very low corrosion rates. Zinc formate was present in the corrosion products. It is suggested that the corrosion is due, at least in part, to the production of formic acid through oxidation of styrene monomer by the peroxidic catalysts, and the slow release of this acid by the cured resin.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
