Occupational exposure to epoxy resins - OSHWiki
Epoxy resins are created by mixing BPA and epichlorohydrin (ECH), which are then reacted so as to create the basic monomer unit of epoxy resin called BADGE or DGEBA. The properties of the cured epoxy resins are determined by a chemical process called curing or hardening. It involves mixing the resin with (poly)amines, aminoamides, phenolic
