EPI-REZ™ Resin 3547-WY-57 is a nonionic dispersion of a high molecular weight epoxy resin in water and 2-propoxyethanol (EGMPE).  It was developed to be similar to EPI-REZ Resin 3540-WY-55 and to be compositionally compliant with many regulations for incidental food contact applications.


  • Moderate viscosity for ease of handling
  • Excellent particle size stability
  • Good discoloration resistance at high temperatures
  • May be formulated for low VOC coatings
  • Can be cured through epoxide and hydroxyl functional groups
