Ukuziphendukela kweshishini le-eptfe libali elinomdla eliye laphuhliswa ixesha elide ukudala imboni kunye nezicelo eziguquguqukayo.Imbali ye-epoxy iqala ngo-1884, xa i-chemist Alfred Einhorn yenza i-compound entsha esuka kwi-ethylene kunye ne-formaldehyde.Le ngqungquthela yayibizwa ngokuba yi "epoxide", eyathi ekugqibeleni yaziwa ngokuba yi-epoxy ngokuyidibanisa ne-polyol okanye i-esters.Ngelixa olu yilo lwantlandlolo lunezicelo ezininzi ezisebenzayo, ukusetyenziswa kwalo kwahlala kulinganiselwe ngenxa yeendleko zalo eziphezulu kunye nokungabikho kwemathiriyeli ekrwada ekhoyo.Ngoo-1940 abaphandi abaliqela basebenza ekuphuculeni ukwakheka kwe-epoxy yokuqala kuquka uRichard Condon waseMelika owafumanisa indlela yokwenza ukuba yomelele ngakumbi esebenzisa iipolyoli ezivela kwiimveliso zepetroleum ezifana necyclohexane oxide kunye nephenol novolak resin.Kwangelo xesha linye izazinzulu zaseBritane zaqalisa ukwenza umfuniselo ngeearhente zokunyanga ezahlukeneyo ezifana neeamines kunye neeasidi ezikhokelela kwimveliso ephuculweyo enokuthi isetyenziselwe ukulamisa imiphezulu efana neplywood iyenza yomelele kunangaphambili kwaye ke ngoko ivula indlela yeendlela zale mihla zokwenziwa kwezinto ezidityanisiweyo.Ngexesha leMfazwe yeHlabathi yesiBini izicelo zomkhosi ze-epoxies zanda kakhulu zidala imfuno yamanqaku angcono ezinto ezikhokelela ababoneleli ukuba baphuhlise iipropathi ezizodwa ezifana nokuxhathisa ubushushu, ukuguquguquka kumaqondo obushushu aphantsi, ukuxhathisa imichiza njl.njl., okubavumela ukuba bahlangabezane neemfuno ezithile ezifunekayo kwimveliso yamacandelo okubhabha.Uphuhliso lwale teknoloji luye lwaqhubeka ukuya kutsho kwiminyaka yoo-1950s apho ukuqhubela phambili kwenziwa kuzo zombini iindlela zokuvelisa iintlaka zokwenziwa kunye nezo zaveliswa ngokudibeneyo phakathi kwemixube yerabha yendalo kunye nemixube yerabha eyenziweyo edityaniswe nezihluzi ezifana neasbestos zenza into esiyaziyo ngoku namhlanje njenge 'elastomers ezizalisweyo' okanye iirubha iiplastiki eziqinisiweyo (FRP).Ekuqaleni kweminyaka yoo-1960 iinkqubo ezahlukeneyo zacokiswa ngokwaneleyo kangangokuba iinkqubo zokuvelisa isambuku semizi-mveliso zinokuphunyezwa zikhokelela kuphuhliso olongezelelekileyo ekongezeni imibala kunye nezinye izongezo ezikhokelela ekusebenzeni okuphezulu kwe-epoxies yale mihla esetyenziswa kumashishini amaninzi ukusukela kulwakhiwo kunye nobunjineli ngokuyila ilungelo loyilo lweemoto. Ukuza kuthi ga kutsha nje izisombululo zokupakishwa kwe-semiconductor ezisetyenzisiweyo kwimixube entsonkothileyo efuna ubuchule obuchanekileyo besinyithi somgubo phakathi kwezinye kunye netekhnoloji yokugquma i-ceramic ebandakanya amasuntswana othuli lwedayimani okuvumela abenzi bezixhobo zokusika bafezekise amanqanaba aphezulu angazange aviwe phambi kwamashumi amabini eminyaka ngaphambi kweli xesha.Lo mgca wexesha ubonisa ukuba sihambe kangakanani ukusukela oko kwaveliswa umva ngo-1884 ukuya kuthi xhaxhe ngokukhula kobunzima obukhula ngokuqhubekayo ngokuqhubekayo nokuguquka kophando olutyhalela phambili imida engaphaya kwalo naluphi na ulindelo lokuqala ngexesha lokuphila kuka-Alfred Einhorn okunokwenzeka okungazange kuphuphe kusenzeka oko kuphelisa uhambo olumangalisayo lwendaleko oludibanisa usuku lwangoku. Ukuqhubela phambili kuya kuba yingenelo kakhulu kwizizukulwana ezizayo ehlabathini lonke .
