In this paper the rheological properties of various epoxy-amine compositions based on the ED-20 epoxy resin were studied. The effectiveness of curing accelerators from among tertiary and quaternary amines has been evaluated. The rheokinetics of the curing processes were studied by the method of rotational viscometry. The times to reach the gel point of the studied systems are determined.

The results of studying the process of curing epoxy resin ED-20 with various amine hardeners by differential scanning calorimetry are presented. The effectiveness of several tertiary amine curing accelerators has been evaluated. The completeness of curing of the epoxy resin and the stoichiometry of the compositions were evaluated by IR spectroscopy.
