EPON™ Resin 1004F


EPON™ Resin 1004F is a solid epoxy resin derived from bisphenol-A and epichlorohydrin. This medium molecular weight epoxy resin has an average of 4.5-5.0 hydroxyl groups per molecule plus the terminal epoxy groups. These epoxy and hydroxyl groups are usually reacted with vegetable oil acids to prepare epoxy resin esters. Epoxy esters derived from EPON Resin 1004F find application as vehicles in appliance primers, automotive primers, and in maintenance coatings. EPON Resin 1004F may be used as a partial replacement for other EPON Resins in amine or polyamide cured epoxy air dry finishes and in phenolic and amino modified epoxy baking systems.


  • EPON Resin 1004F contains a specific amount of esterification catalyst to control esterification reactions with vegetable oil acids.
  • EPON Resin 1004F is supplied in very large lots (greater than 100M pounds) with uniform properties.
  • EPON Resin 1004F provides special solution viscosity and reactivity properties when combined with other EPON Resins in air dry amine or polyamide cured epoxy coatings and in epoxy-phenolic or amino converted baking systems.
