The hardening reaction of a two-can water epoxy polyamide system was investigated on the basis of the variation of the viscoelastic moduli G' and G". Unpigmented (clear varnish) and TiO2 pigmented formulations, at two different TiO2 concentrations, were taken into account. Time and frequency sweep procedures were carried out using the stress-controlled rheometer Haake RS 150. The behavior of G' and G" vs time was fitted to a four-parameter asymptotic model through the whole course of the hardening process. Frequency sweep data, obtained at increasing times during the whole hardening process, were plotted to the generalized Cole and Cole behavior model and the corresponding mechanical spectra were drawn. An interpretation for some aspects of the cross-linking progress is discussed and possible future developments are briefly outlined.
