Rheological characterization of a gelcasting system based on epoxy resin

The in situ polymerization of an aqueous system comprising epoxy resin and polyamine has been developed to consolidate ceramic suspensions in our previous study. In the present work, the polymerization of the aqueous solution was investigated by an oscillatory method in terms of storage modulus G′. The influences of the epoxy resin on alumina suspensions were evaluated by means of zeta potential and viscosity. The consolidation behaviors of suspensions with different solids were also studied.
