ARALDITE® ECN 1273

ARALDITE® ECN 1273 is a polyepoxide resin produced by reacting epichlorohydrin with an ortho-cresol formaldehyde novolac. The molecular weight of the novolac controls the resin’s molecular weight and functionality, which ranges from 2.5 to 5.5 reactive groups per molecule. Unlike conventional bisphenol-A based epoxy resins, this polyepoxide offers multiple reactive sites, enhancing crosslinking density and performance.

Mixing and Handling

All hardeners used to cure conventional epoxy resins can be used to cure the ECN resins. Generally, ARALDITE® ECN 1273 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
