Monoacid/Diacid Combination as Corrosion Inhibitors in Antifreeze Formulations 900804

The traditional methods of protecting aluminum surfaces in automotive cooling systems are under scrutiny because of problems caused by high levels of certain inhibitors, particularly silicate, and the lack of protection against crevice corrosion. This paper discusses new monoacid/diacid inhibitor technology which improves protection of aluminum, increasingly used in automotive engines, and it also extends the useful life of the automotive engine coolant.
