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. Ukuphuhliswa kobu bugcisa kuye kwaqhubeka kakuhle ukuya kutsho koo-1950 apho ukuqhubela phambili kwenziwa kuzo zombini iindlela zokuvelisa iintlaka zokwenziwa kunye nezo zaveliswa ngokudibeneyo phakathi kwemixube yerabha yendalo kunye nemixube yerabha yokwenziwa kudityaniswe nezihluzi ezifana neasbestos zenza into esiyaziyo ngoku namhlanje 'njengeelastomers ezigcwalisiweyo' okanye iirabha eziqiniswe iiplastiki (FRP). Ekuqaleni kweminyaka yee-1960 iinkqubo ezahlukeneyo zacocwa ngokwaneleyo kangangokuba iinkqubo zokuvelisa isambuku semizi-mveliso zinokumiselwa zikhokelela kuphuhliso olongezelelekileyo ekongezeni imibala kunye nezinye izongezo ezikhokelela ekusebenzeni okuphezulu kwe-epoxies yale mihla esetyenziswa kumashishini amaninzi ukusukela kulwakhiwo kunye nobunjineli ngoyilo lweemoto ukuya kuthi ga kutsha nje iisemiconductor zokupakisha izisombululo ezisetyenzisiweyo kunye nezixhobo ze-ceramic eziyimfuneko kunye nezinye izinto eziyimfuneko. Itekhnoloji ebandakanya amasuntswana othuli lwedayimani evumela abenzi bezixhobo zokusika bafikelele kumanqanaba aphezulu angazange aviwe ngaphambili kumashumi amabini eminyaka ngaphambi kweli xesha. Lo mgca wexesha ubonisa ukuba sihambe kangakanani ukusukela oko kwaqalwa ngo-1884 ukuya kuthi ga ekukhuleni kobunzima obukhula ngokukhula ngokuqhubekayo ngokukhula kophando olutyhaphaza imida engaphaya kwayo nayiphi na into ebilindelwe ngu-Alfred Einhorn wobomi bakhe bokuvula amathuba angazange aphuphe anokwenzeka, oko ke kupheza uhambo olumangalisayo lwendaleko oludibanisa inkqubela phambili yekamva lehlabathi jikelele.
