The object of this study was to investigate conditions which would effect long term packaging of ethylene glycol antifreeze. Factors investigated were pH, dilution, different inhibitor systems and different metals. Aluminum and tin-coated steel panels were partially immersed in ethylene glycol solutions contained in test jars at room temperatures for a period of ten years. Inhibitors used in this study included borax, borax-glycol condensate, mercaptobenzothiazole, and the sodium salt of mercaptobenzothiazole. pH values ranging from 6 to 10.6 were used. Test solutions contained 0, 3 and 66-23 water. No system was adequate for 10 years storage. All systems exhibited corrosion in the liquid phase andor the vapor phase.
