Bisphenol F epoxy resin, also known as bisphenol F diglycidyl ether, referred to as BPF, is prepared by the reaction of phenol and formaldehyde under acid catalysis to produce bisphenol F, and then with epichlorohydrin in the presence of sodium hydroxide polycondensation reaction. This is a new type of epoxy resin developed in order to reduce the viscosity of bisphenol A epoxy resin itself and have the same properties. It is usually a liquid bisphenol F epoxy resin obtained by the reaction of bisphenol F (diphenol methane) and epichlorohydrin under the action of NaOH.
