ARALDITE® ECN 1280

ARALDITE® ECN 1280 is a polyepoxide resin produced by reacting epichlorohydrin with an ortho-cresol formaldehyde novolac. The novolac’s molecular weight determines the resin’s molecular weight and functionality, which ranges from 2.5 to 5.5 reactive groups per molecule. Compared to conventional bisphenol-A based epoxy resins, this polyepoxide offers multiple reactive sites, resulting in enhanced crosslinking and improved material properties.

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 1280 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
