ERISYS® GE-11

ERISYS® GE-11

ERISYS GE-11, epoxidized para-tertiary butyl phenol, is an aromatic mono-epoxide. GE-11 is intended for use as a reactive diluent for high viscosity epoxy resins and it is compatible at all concentrations with those resins. Resin/diluent blends can be cured using any curing agent for epoxy resins. GE-11, due to its aromatic structure, is not as efficient in viscosity reduction as aliphatic diluents ERISYS GE-5, GE-6, GE-7, or GE-8. However, performance properties of epoxy formulations diluted with GE-11 are modified less than those of systems containing the aliphatic monofunctional diluents. Depending on concentration, properties such as gel time, room temperature strength, and modulus of a GE-11 diluted formulation remain relatively unchanged compare to an undiluted resin. However, a decline in elevated temperature performance, as indicated by decreasing Tg with increasing GE-11 concentration occurs. Cured formulations containing GE-11 exhibit excellent moisture resistance. ERISYS GE-11’s low vapor pressure, low odor and exceptionally low residual epichlorohydrin level make it ideally suited for environmentally difficult applications. Another feature of GE-11 is its ability to reduce the tendency of certain epoxy resins to crystallize, thereby producing formulations with improved homogeneity.
