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.Ngaso leso sikhathi ososayensi baseBrithani baqala ukuhlola izinto ezelaphayo ezihlukene ezifana nama-amine nama-asidi okwaphumela kumkhiqizo othuthukisiwe owawungase usetshenziselwe izindawo zokulalisa ezifana ne-plywood eyenza ibe namandla kunangaphambili futhi ngaleyo ndlela ivula 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 kwaze kwaba ngawo-1950s lapho kwenziwa intuthuko kuzo zombili izindlela zokukhiqiza izinsalela zokwenziwa kanye nalezo ezikhiqizwa ngokuhlanganyela phakathi kwezingxube zenjoloba yemvelo kanye nezingxube zenjoloba zokwenziwa ezihlanganiswe nezigcwali ezifana ne-asbestos ezidala lokho manje esikwaziyo namuhla ngokuthi 'ama-elastomer agcwele' noma amapulasitiki aqinisiwe ama-rubber (FRP).Ngasekuqaleni kwawo-1960 izinqubo ezihlukahlukene zazicwengisiswe ngendlela ephawulekayo kangangokuthi amasistimu okukhiqiza ngobuningi bezinga lezimboni ayengase asetshenziswe okuholela ekuthuthukisweni okwengeziwe ekwengezeni imibala nezinye izithasiselo okudala ukusebenza okuphakeme kwesimanje kwama-epoxies asetshenziswa kuzo zonke izimboni eziningi kusukela kwezokwakha nobunjiniyela ngokusebenzisa ilungelo lokuklama izimoto. kuze kube muva nje izixazululo zokupakisha ze-semiconductor zisebenzisa ukwakheka okuyinkimbinkimbi okudinga amandla anembile ensimbi ye-powder phakathi kokunye kanye nobuchwepheshe bokumboza nge-ceramic obuhlanganisa izinhlayiya zothuli lwedayimane okuvumela abakhi bamathuluzi okusika bathole amazinga aphezulu ukusebenza kahle okungakaze kuzwakale ngaphambi kwamashumi amabili eminyaka ngaphambi kwalesi sikhathi.Lo mugqa wesikhathi ukhombisa ukuthi sesihambe kangakanani kusukela ekusungulweni kokuqala emuva ngo-1884 okuholela ekukhuleni okwandayo okukhulayo okwenziwa kusebenze ngokuqhubekayo ucwaningo oluqhubekayo olucindezela imingcele edlula noma yikuphi okwakulindelwe ekuqaleni ngesikhathi sokuphila kuka-Alfred Einhorn amathuba okuvula angakaze aphuphe angenzeka ngaleyo ndlela aqede uhambo oluphawulekayo lokuziphendukela kwemvelo oluxhumanisa usuku lwamanje. intuthuko ezuzisa kakhulu izizukulwane ezizayo emhlabeni wonke.
