Epoxy Phenol Novolacs (EPNs)

Huntsman’s range of Araldite® epoxy novolac (EPN) resins are designed to provide increased levels of thermal stability and chemical resistance. Our EPN resins are recommended in formulations for high performance applications requiring excellent chemical resistance, solvent resistance and exceptional high temperature resistance, greater than standard Bisphenol A epoxy resins. These resins can be used in blends to upgrade the performance offered by bisphenol A and F-based epoxy resins.
