Scope
This document describes a method of using differential scanning calorimetry (DSC) to measure the heat of reaction generated during the cross-linking of epoxy resins and calculating the cross-linking degree based on this result. This document is suitable for epoxy resin systems with moderate or slow cross-linking reaction rates. This document is not suitable for systems with fast cross-linking reaction rates at room temperature.
