Engine Coolant Testing Fourth Volume ASTM STP 1335

Long Term Serviceability of Elastomers     in Modern Engine Coolants Hertz, D.L. Jr., Farinella, A.C., and Bussem, H. Seals Eastern, Inc. 1999.  ABSTRACT      The aging of elastomers in engine coolants after extended periods of service can be both a physical process (stress / strain relaxation) and/or a chemical change. Engine coolants are essentially aqueous and non-aqueous electrolytes coupled with inorganic inhibitor systems, as well as new organic systems. The long-term effects of this environment are reviewed. Chemical and functional tests are utilized to model these aging processes. This review will offer a better understanding of the long-term suitability of typical candidate elastomers.
