Abstract
Epoxy resin compositions contain (i) a polyepoxide resin; (ii) a benzofuran diol component, a benzofuran di-epoxide component, or mixture thereof; and (iii) a curing agent, which upon curing, provides a cured resin exhibiting improved chemical and physical characteristics. The epoxy resin composition may also contain a toughening agent to further enhance the cured resin's physical characteristics.
