ERISYS® GE-20

ERISYS® GE-20

ERISYS GE-20 is a low viscosity, aliphatic diepoxide. It is intended for use as a reactive diluent for high viscosity epoxy resins. It is compatible at all concentrations with those resins and resin/diluent blends can be cured using any epoxy resin curing agent. As a result of its chemical structure GE-20 is not as efficient in viscosity reduction as the aliphatic monofunctional reactive diluents ERISYS GE-5, GE-6, GE-7, and GE-8. However, the performance properties of epoxy formulations diluted with GE-20 are modified to a lesser degree than those of systems containing the aliphatic monofunctional diluents. Depending on concentration, properties such as gel time, strength, and modulus of a GE-20 diluted formulation remain relatively unchanged compared to an undiluted resin. The difunctionality of GE-20 helps to produce formulations with improved chemical and heat resistance compared to formulations containing monofunctional diluents.
