Substitution of Tolyltriazole for Mercaptobenzothiazole in Military Coolant Inhibitor Formulations

Abstract

The object of this study was to determine the feasibility of substituting tolyltriazole (TT) for mercaptobenzothiazole (MBT) in the corrosion inhibitor package used in military coolants. ASTM Glassware Corrosion Tests (D 1384) and Simulated Service Tests (D 2570) were conducted on various blends of antifreeze inhibitors with different percentages of sodium tolyltriazole (NaTT). The NaTT caused foaming in the tests, but a silicone type antifoam agent was found which controlled the foaming. Results of these tests were correlated with similar tests containing the amount of MBT recommended in coolant specifications (0.4% of the sodium salt). 0.15% was found to be the optimum percentage of NaTT.
