ROMAO, Benedita M. V.; DINIZ, Milton F.; PARDINI, Luiz C.  e  DUTRA, Rita C. L.. FT-IR MIR and FT-NIR applied to the study of reaction of epoxy systems. Polímeros [online]. 2004, vol.14, n.3, pp.142-149. ISSN 1678-5169.  http://dx.doi.org/10.1590/S0104-14282004000300008.

The cure reaction of epoxy resin (EP) and curing agents based on polymercaptans (SH), amine-phenol and modified amine was studied in the MIR and NIR spectral regions. It was observed that the FT-NIR shows better the spectrometric changes of the reactions studied, which makes it possible to detect the curing agent in lower contents in epoxide systems.
