EPI-REZ™ Resin 7521-WH-57


EPI-REZ™ Resin 7521-WH-57 is a 57% weight solids, non-ionic aqueous dispersion of a modified EPON™ Resin 1001 solid epoxy resin. This low VOC and HAPs-Free1 waterborne epoxy dispersion can be formulated into high performance coatings for metal and concrete substrates. EPI-REZ™ Resin 7521-WH-57 exhibits good compatibility with many water-reducible amine curing agents and is designed for use with either EPIKURE™ Curing Agent 8530-W-75 or EPIKURE™ Curing Agent 6870-W-53.

EPI-REZ Resin 7521-WH-57, when combined with EPIKURE™ 8530-W-75, provides a cost effective, high performance alternative to traditional waterborne epoxy coatings systems. This new system is called the NextGen Epoxy™ Waterborne System.


  • Low VOC for concrete and metal coatings (<100 g/L)
  • Superior corrosion resistance (1000 hours ASTM B117)
  • Excellent adhesion to metal and concrete
  • Fast dry times and good hardness development
  • Long pot life with high gloss profile
  • High solids with low viscosity for easier handling
