| Abstract | ||
| In this study viscosity (η) of diglycidyl ether of bisphenol A / triethylenetetramine (DGEBA/TETA) system were measured through curing using a Brookfield viscometer at four different temperatures (30, 45, 60 and 80) °C. The measurements were carried out for two hardener/resin ratios (13 and 20) phr. The gel time was calculated for each hardener/resin ratio formulation; from the viscosity experimental data. The results showed that the gel time decrease with increasing curing temperature for each hardener/resin ratio formulation. Viscosity profiles were described by a model based on the Boltzmann function. The fitted results agreed well with the experimental values. | ||
