All the reactive diluents have a low viscosity and mixed with both the epoxy resin EDR-20 and hardened-polyethylenepolyamine in any proportions. Application of active diluents can solve a number of technological problems: an opportunity to increase the volume of the final product and increase the initial temperature without risk of overheating and boiling system, and to increase the filler content in the composite, which in turn can increase the electrical conductivity. Viscosity reduction due to the use of active diluents allows more fully remove from the system any air bubbles trapped during mixing, respectively; it gives the possibility of obtaining polymers with better optical characteristics.
