Evaluation
The above plot shows a DSC curve from a single heating of a melamine formaldehyde resin (MF).
The glass transition at approx. 61°C (midpoint) is overlapped by a large endothermal enthalpy relaxation peak (peak temperature 69°C) and is immediately followed by an exothermal curing with a peak temperature of approx. 136°C and a reaction
enthalpy of 48 J/g.
A temperature-modulated DSC (TM-DSC) measurement (not presented here) would be able to separate the reversing glass transition from the non-reversing endothermal relaxation and the exothermal reaction peaks.
