Ukuziphendukela kwemvelo kwemboni ye-eptfe kuyindaba ethakazelisayo eye yathuthukiswa ngokuhamba kwesikhathi ukudala imboni enezinhlelo zokusebenza zokuguqula.Umlando we-epoxy uqala ngo-1884, lapho umakhemikhali u-Alfred Einhorn ehlanganisa i-compound entsha evela ku-ethylene ne-formaldehyde. Le nhlanganisela yayibizwa ngokuthi "i-epoxide", eyagcina yaziwa ngokuthi i-epoxy ngokuyihlanganisa ne-polyol noma i-esters. Nakuba lokhu kwakhiwa kwasekuqaleni kwakunezinhlelo eziningi ezisebenzayo, ukusetshenziswa kwayo kwahlala kulinganiselwe ngenxa yezindleko zayo eziphezulu kanye nokuntuleka kwezinto zokusetshenziswa ezitholakalayo. Ngawo-1940 abacwaningi abaningana basebenza ekuthuthukiseni ukwakheka kokuqala kwe-epoxy kuhlanganise no-American Richard Condon owathola indlela yokwenza ukuthi iqine ngokwengeziwe usebenzisa ama-polyols atholakala emikhiqizweni ye-petroleum efana ne-cyclohexane oxide ne-phenol novolak resin. Ngesikhathi esifanayo ososayensi baseBrithani baqala ukuhlola izinto ezelaphayo ezihlukene ezifana nama-amine nama-asidi okwaphumela kumkhiqizo othuthukisiwe owawungase usetshenziselwe izindawo zokulalisa ezifana ne-plywood ewenza uqine kunangaphambili futhi ngaleyo ndlela kuvula indlela yamasu okukhiqiza izinto ezibonakalayo eziyinhlanganisela yesimanje . Phakathi neMpi Yezwe II izicelo zezempi zama-epoxies zanda ngokumangazayo zadala isidingo samabanga angcono nakakhulu wezinto ezibonakalayo eziholela abahlinzeki ukuba bathuthukise izakhiwo eziyingqayizivele ezifana nokumelana nokushisa, ukuguquguquka emazingeni okushisa aphansi, ukumelana namakhemikhali njll., okubavumela ukuba bahlangabezane nezidingo ezithile ezidingekayo ekukhiqizeni izingxenye zezindiza . Ukuthuthukiswa kwalobu buchwepheshe kwaqhubeka kahle ngeminyaka yawo-1950s lapho kwenziwa khona intuthuko kuzo zombili izindlela zokukhiqiza izinsalela zokwenziwa kanye nalezo ezikhiqizwa ngokuhlanganyela phakathi kwezingxube zenjoloba yemvelo kanye nezingxube zenjoloba zokwenziwa ezihlanganiswe nama-filler afana ne-asbestos edala lokho esikwazi manje ngokuthi 'ama-elastomer agcwele' noma amapulasitiki aqinisiwe amarabha (FRP). Ekuqaleni kwawo-1960 izinqubo ezihlukahlukene zazicwengisiswe ngokwanele kangangokuthi izinhlelo zokukhiqiza ngobuningi bezinga lezimboni zingasetshenziswa okuholela ekuthuthukisweni okuqhubekayo ekwengezeni imibala nezinye izithasiselo okudala ukusebenza okuphezulu kwanamuhla kwe-epoxies esetshenziswa kuzo zonke izimboni eziningi kusukela kwezokwakha nobunjiniyela ngokusebenzisa ukwakhiwa kwezimoto kuze kube muva nje izixazululo zokupakisha ze-semiconductor ezisetshenziswa eziyinkimbinkimbi nezinye ezidinga i-powder coramic. ubuchwepheshe obubandakanya izinhlayiya zothuli lwedayimane obuvumela abenzi bamathuluzi okusika bathole ukusebenza kahle kwamazinga aphezulu okungakaze kuzwakale ngaphambi kwamashumi amabili eminyaka ngaphambi kwalesi sikhathi . Lo mugqa wesikhathi ubonisa ukuthi sesihambe ibanga elingakanani kusukela ekusungulweni kokuqala emuva ngo-1884 okuholela ekukhuleni okuyinkimbinkimbi okukhulayo okwenziwa kusebenze ngokuqhubekayo ucwaningo oluqhubekayo okwamanje olucindezela imingcele edlula noma yikuphi okwakulindelwe ekuqaleni ngesikhathi sokuphila kuka-Alfred Einhorn amathuba angakaze aphuphe angenzeka ngaleyo ndlela aqede uhambo oluphawulekayo lokuziphendukela kwemvelo oluxhumanisa intuthuko yesizukulwane sanamuhla esizuzisa kakhulu emhlabeni wonke.
