Master curves and lifetime prediction for the epoxy system badge n = 0/m-XDA by thermogravimetric analysis

Master plots were used to corroborate Rn‐type mechanisms calculated in a previous study, using the method proposed by Criado et al. (Thermochim Acta 1989, 147, 377). Analysis of experimental data seems to belong to the family of decelerated curves (Rn) in the range of conversion studied. The lifetime of the system diglycidil ether of bisphenol A (BADGE n = 0)/m‐xylylenediamine (m‐XDA) for different decelerated mechanisms was calculated using thermogravimetric analysis. From the experimental data it was found that the optimum temperature range of use for this material is 60–100°C for all Rn‐type mechanisms, at which corresponding lifetimes range between 190 years and 1 year. © 2001 John Wiley & Sons, Inc.
