ARALDITE® ECN 9511

ARALDITE® ECN 9511 is a polyepoxide resin synthesized by reacting epichlorohydrin with an ortho-cresol formaldehyde novolac. The molecular weight of the novolac influences the resin’s molecular weight and functionality, which typically ranges from 2.5 to 5.5 reactive groups per molecule. Unlike conventional bisphenol-A based epoxy resins, this polyepoxide contains multiple reactive sites, enabling higher crosslink density and enhanced performance.

Technical Details & Test Data

Mixing and Handling

All hardeners used to cure conventional epoxy resins can be used to cure the ECN resins. Generally, ARALDITE® ECN 9511 exhibit a shorter gel time and cure faster than conventional epoxy resins under the same conditions.

It may be advantageous for particular applications to prepare solutions of these resins. This is easily accomplished since the resins are soluble in many of the more common solvents. For example:

  • Acetone
  • PMA
  • Toluene-MIBK
  • Xylene-MIBK
  • Toluene
  • Chloroform
  • Ethylene Chloride
