ERISYS GE-21
ERISYS GE-21
ERISYS GE-21, epoxidized Butanediol, is a low viscosity, aliphatic, diepoxide. It is intended for use as a reactive diluent for high viscosity epoxy resins. ERISYS® GE- 21 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, this product is not as efficient in viscosity reduction as the aliphatic mono-functional reactive diluents ERISYS GE-5, GE-6, GE-7, and GE-8. However, the performance properties of epoxy formulations diluted with this product are modified to a lesser degree than those of systems containing the aliphatic monofunctional diluents. Depending on the concentration, properties such as gel time, strength, and modulus of an ERISYS GE-21 diluted formulation remain relatively unchanged compared to an undiluted resin. The di-functionality of ERISYS GE-21 helps to produce formulations with improved chemical and heat resistance compared to formulations containing monofunctional diluents.
This product does not affect the pot life of precatalyzed epoxy resin/acid anhydride formulations. Formulations containing this product exhibit excellent wettability making them ideal candidates for composite and impregnation applications. ERISYS GE-21 has low moisture, hydrolyzable chloride, and residual epichlorohydrin contents. Its exceptionally low color makes this product the diluent of choice in color critical applications.
ERISYS GE Series glycidyl ether monomers and modifiers are low molecular weight epoxy-functional products based on alcohols, glycols, and phenols. The product line covers a broad range of TSCA-approved monomers from mono-epoxy functional to multi-epoxy functional materials.
