This document specifies a method whereby the heat of reaction generated during epoxy resin crosslinking is measured by differential scanning calorimetry (DSC). The degree of crosslinking is determined based on this result.<\/p>\n
This method is applicable to epoxy resin systems with a moderate or slow crosslinking-reaction speed. It might not be applicable to systems with a fast crosslinking-reaction speed at ambient temperature.<\/p>\n
