Epoxy Phenol Novolac (EPN) - Corrosionpedia
An epoxy phenol novolac (EPN) is an epoxy resin where the epoxide functional group is attached to the phenolic oxygen of a phenolic novolac. As such, each phenol oxygen of the novolac resin is attached with a -CH 2 - (C 2 H 3 O) group, where - (C 2 H 3 O) is a three-membered epoxide ring. A single EPN polymer contains many epoxide groups ...
