EPI-REZ™ Resin 3514-W-56


EPI-REZ™ Resin 3514-W-56 is a nonionic, waterborne dispersion of a liquid epoxy resin and was developed primarily for glass fiber sizing.  For this application, EPI-REZ 3514-W-56 provides good particle size stability and fiber lubricity while maintaining a balance of fiber wet out and composite mechanical properties.


  • Physically stable, nonionically dispersed, low molecular weight epoxy resin
  • Excellent particle size stability
  • Low viscosity film former
  • Helps to impart lubricity and wetting characteristics for fiber sizing
  • Can be cured through epoxide functional groups
