Abstract : Numerous commercial polyurethane elastomers were evaluated using Differential scanning Calorimetry (DSC) after a variety of aging conditions including exposure to fuel and water for up to 42 days. The results indicated changes in the material as a result of aging conditions. These material or morphology changes were monitored by studying the thermal transitions detected by DSC. A general trend in thermal behavior of the conventional tank coatings was observed.
