A study of the changes in a LARC–TPI adhesive during a three-stage thermal curing process has been conducted. The multistage curing conditions followed commonly used industrial curing specifications. Using thermogravimetric analysis plus gas chromatography plus mass spectrometry, the gasses involved in the curing were identified. Water analysis was performed by two separate techniques and supplementary information gathered using Fourier transform infrared spectroscopy. These analytical studies permitted determination of the degree of cure at each stage and to determine whether any degradation is taking place under curing condition.
