Glass Fiber Filled Epoxy — Curing

Analysis and optimization of the curing process of epoxy resins can be easily carried out using differential scanning calorimetry. Presented here is a measurement on a glass fiber filled epoxy measured in the DSC 200 F3 Maia®. The two-step exothermal cross-linking reaction slightly above the glass transition (at 101.5°C) is clearly visible during the first heating of the sample. After a controlled cooling at 5 K/min, the sample was heated a second time. Only a weak glass transition is visible at a higher temperature (142.4°C) compared to the first heating cycle. 

DSC 3500 Sirius

The DSC 3500 Sirius combines compactness, robustness and ease-of-use with high detection sensitivity, thus offering optimal conditions for quality assurance and failure analysis in areas such as foods, cosmetics, polymers, technical textiles, and organic and inorganic materials.
