“…For high-purity epoxy resins, which are typically needed for the electronic industry to avoid chemical or galvanic corrosion, the ion content is often around 50 ppm or less, whereas for ionic liquid cured epoxies it can reach values three orders of magnitudes higher, up to 100 000 ppm. [12] Although DEA has been used successfully for a variety of different materials including cement, [13] wood panels [14] or dental resins [15] and a multitude of manufacturing techniques such as pultrusion [16] and autoclave processing, [17] no complete study with ionic liquids as hardener, that is, from modeling up to an industrial composite manufacturing process, has been published until now to the best knowledge of the authors. Due to the ionic nature of the imidazolium salts, difficulties regarding its high conductivity in combination with DEA as characterization method are expected, which could affect cure prediction modeling and in situ monitoring.…”
