ERISYS RDGE, epoxidized resorcinol, is a very low viscosity aromatic diepoxide. When properly formulated, ERISYS® RDGE can be used as the sole resin in an epoxy formulation. Its primary use, however, is as a reactive modifier. All epoxy resin curing agents are compatible with ERISYS RDGE and RDGE/epoxy resin blends. As a result of this products high reactivity, formulators have increased latitude in curing agent selection.

Epoxy formulations modified with ERISYS RDGE exhibit viscosity reduction, significantly faster cures, and high cross-link densities. Higher cross-link density produces higher strengths, improved toughness, better heat resistance, and better chemical resistance than formulations modified with other reactive diluents.

Due to the purity of ERISYS RDGE, crystallization of this resin can occur. The crystallized resin can be liquified without damage to the resin by opening the drum bung and heating to a temperature of 50°C to 60°C. Re-liquified resin should be mixed before sampling or partial use of the drum. This product can be stored at 50°C to prevent re-crystallization, however, it is not recommended to store at 50°C for more than two weeks.
