EPI-REZ™ Resin 7520-WD-52


EPI-REZ™ Resin 7520-WD-52 is a 52% weight solids, non-ionic aqueous dispersion of a modified EPON™ Resin 1001 solid epoxy resin. This low VOC and HAPs-free1 waterborne epoxy dispersion provides high performance coatings for metal and concrete substrates.  EPI-REZ™ Resin 7520-WD-52 exhibits good compatibility with many water-reducible amine curing agents, and is designed for use with either Research Curing Agent RSC-4431 or EPIKURE™ Curing Agent 6870-W-53. 

EPI-REZ Resin 7520-WD-52, when combined with Research Curing Agent RSC-4431, provides a cost-effective, high performance alternative to traditional solvent-borne coatings systems.  This new system is called the NextGen Epoxy™ Waterborne System. 


  • Ultra-low VOC for concrete (<50 g/L) and metal (<100 g/L) coatings
  • 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
  • Improved product shelf and freeze-thaw stability

1Hazardous air pollutants as defined by the US Environmental Protection Agency .
