ERISYS^® GE-22

ERISYS GE-22, epoxidized cyclohexanedimethanol, is a low viscosity, cycloaliphatic diepoxide. It is intended for use as a reactive diluent for high viscosity epoxy resins. GE-22 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-22 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-22 are modified to a lesser degree than those systems containing the aliphatic monofunctional diluents. Depending on concentration, properties such as gel time, strength, and modulus of a GE-22 diluted formulation remain relatively unchanged compared to an undiluted mix (see table and graphs below). The difunctionality of GE-22 helps to produce formulations with improved chemical and heat resistance compared to formulations containing monofunctional diluents.

The cycloaliphatic nature of GE-22 suggest its use in formulations requiring outdoor weathering resistance. Formulations containing ERISYS GE-22 exhibit outstanding creep resistance making them ideal for high performance grouts and structural applications. GE-22 improves a formulation’s wettability. This diluent does not effect the pot life of precatalyzed epoxy resin/acid anhydride formulations.
