EPON™ Resin 863


EPON Resin 863 is a low viscosity, undiluted, difunctional epoxy resin produced from bisphenol-F (BPF) and epichlorohydrin and was specially developed to provide good resistance to crystallization.  When cross-linked or hardened with appropriate curing agents, very good mechanical, adhesive, chemical and electrical properties are obtained.


  • Low viscosity
  • Low color
  • Improved crystallization resistance relative to EPON Resin 862 and diluted BPA epoxy resins
  • Can be blended with EPON Resin 828 and other epoxy resins
  • Reacts with a full range of epoxy curatives
  • Good balance of mechanical, adhesive, and electrical properties
  • Good chemical resistance
