Development of an Antifreeze Extender and Water Inhibitor for Automotive Cooling Systems.

摘要

The object of this study was to develop an inhibitor combination that when added to used antifreeze with depleted inhibitors (intended for disposal) would extend the use of the antifreeze for at least one year. It was further intended that this inhibitor combination would replace the presently used Federal Specification 0-I-490, 'Inhibitor, Corrosion, Liquid Cooling System' in water-cooled automotive cooling systems. Results of this study show that the inhibitor designated as Blend 18 is effective in both applications. (Author)
