Cashew nut shell liquid (CNSL) is a natural phenolic compounds that is non-edible biomass. A novel diglycidyl ether (BCNDGE) derived from CNSL was synthesized and used as a building block to formulate an epoxy resin. Epoxy resins were cured from BCNDGE and commercial diglycidyl ether (BPADGE) with acid anhydride hardener. BCNDGE content improved the thermal stability and flexibility of the epoxy compared with commercial BPADGE-based epoxy. Hence, BCNDGE is a promising novel diglycidyl ether candidate with high biomass content to act as an alternative to petroleum-based chemicals for epoxy resins.
