Iko kushanduka kweiyo eptfe indasitiri inyaya inonakidza yakagadziridzwa nekufamba kwenguva kugadzira indasitiri ine revolutionary application.Nhoroondo ye epoxy inotanga muna 1884, apo chemist Alfred Einhorn akagadzira mutsva mutsva kubva ethylene uye formaldehyde. Komisheni iyi yainzi "epoxide", iyo yakazozivikanwa se epoxy nekuisanganisa ne polyol kana esters. Kunyange zvazvo kuumbwa kwepakutanga uku kwaiva nekushanda kwakawanda, kushandiswa kwayo kwakaramba kuine zvishoma nekuda kwekudhura kwayo uye kushayikwa kwezvinhu zviripo. Mumakore ekuma1940 vatsvakurudzi vakati wandei vakashanda pakuvandudza maumbirwo ekutanga epoxy kusanganisira American Richard Condon akawana kuti angaite sei kuti igare yakasimba achishandisa mapolols anobva muzvigadzirwa zvepetroleum secyclohexane oxide uye phenol novolak resin. Panguva imwe cheteyo masayendisiti eBritain akatanga kuyedza nemishonga yakasiyana-siyana yakaita semaamine nemaasidhi zvichikonzera chigadzirwa chakavandudzwa chaigona kushandiswa pakuisa marara senge plywood ichiita kuti ive yakasimba kupfuura kare nekudaro kugadzira nzira dzemazuva ano macomposites ekugadzira zvinhu. Munguva yeHondo Yenyika II zvikumbiro zvemauto zveepoxies zvakawedzera zvakanyanya kugadzira kudiwa kwemagiredhi ari nani ezvezvinhu zvinotungamira vatengesi kuti vagadzire zvinhu zvakasarudzika senge kupisa kupisa, kuchinjika pakudziya kwakadzika, makemikari kuramba nezvimwewo, zvichivabvumira kuzadzisa zvinodiwa chaizvo mukugadzirwa kwezvikamu zvendege. Kuvandudzwa kweiyi tekinoroji kwakazoenderera mberi kusvika kuma1950 uko kufambiswa mberi kwakagadzirwa mune ese ari maviri ekugadzira resins nzira dzekugadzira pamwe nedziya dzakagadzirwa pamwe chete pakati pechisikigo rabha & yekugadzira rabha musanganiswa wakasanganiswa nemafirita akaita seasbestos achigadzira izvo zvatiri kuziva nhasi se 'akazadzwa elastomers' kana marabha akasimbiswa mapurasitiki (FRP). Pakazosvika ma1960 maitiro akasiyana akakwenenzverwa zvakaringana zvekuti maindasitiri egiredhi ekugadzira akawanda masisitimu anogona kuitwa achitungamira mberi kune kuwedzera mavara & zvimwe zvekuwedzera zvinopa kusimuka kwemazuva ano epoxies akagadziridzwa epoxies anoshandiswa mumaindasitiri mazhinji kubva pakuvaka & engineering kuburikidza nekugadzira mota kusvika nguva pfupi yadarika semiconductor yekurongedza zvigadziriso zvakashandiswa zvakaomesesa zvigadziriso zvehupfu pamwe nezvimwe zveceramic zvigadziriso zvehupfu. matekinoroji anosanganisira madhaimani eguruva matumbu anobvumira vanogadzira maturusi ekucheka kuti vakwanise kukwirira mazinga asina kunzwika makore makumi maviri chete isati yasvika.
