EPI-REZ™ Resin 7720-W-50

Description

EPI-REZ Resin 7720-W-50 is a nonionic, waterborne epoxy dispersion based on a modified EPON™ Resin 1001-type solid epoxy resin. It is supplied in water at 50% solids by weight.  This dispersion can be formulated to provide the performance of traditional solvent-based epoxy coatings at an ultra-low VOC (<50 g/L). EPI-REZ Resin 7720-W-50 may be used in non-HAP waterborne formulations for metal and concrete substrates. EPI-REZ Resin 7720-W-50 exhibits good compatibility with water-reducible amine curing agents. A variety of EPIKURE™ curing agents may be used with EPI-REZ Resin 7720-W-50 (e.g., EPIKURE Curing Agent 6870-W-53, EPIKURE Curing Agent 8530-W-75, EPIKURE Curing Agent 8537-WY-55).
