EPON™ Resin 830


EPON Resin 830 is a slightly higher molecular weight BPA liquid epoxy as compared to EPON 828. The resin itself is resistant to crystallization and also in blends with HELOXY™Modifiers.   EPON Resin 830 is somewhat higher in viscosity than EPON Resin 828, although the viscosity is still easily handled. It provides greater reactivity when combined with most curing agents.


  • Slightly higher viscosity than standard liquid epoxy
  • Very good resistance to crystallization
  • Higher reactivity at room temperature
  • Low color
  • Good chemical resistance
