Mu kubaka irangi ryo hasi rya epoxy resin, dukoresha urwego rwa primer, urwego rwo hagati n'urwego rwo hejuru rwo hejuru.
Urupapuro rw'ibanze ni rwo ruba ruri hasi cyane mu irangi rya epoxy resin, uruhare runini ni ugukina ingaruka za sima ifunze, gukumira umwuka w'amazi, umwuka, peteroli n'ibindi bintu kwinjira, kongera uburyo ubutaka bufatana, kwirinda ko irangi riva hagati mu gihe cy'ibikorwa, ariko kandi no gukumira gusesagura ibikoresho, no kunoza imikorere myiza mu bukungu.
Igiti cyo hagati kiri hejuru y'urwego rwa primer, gishobora kunoza ubushobozi bwo gutwara imizigo, kandi gishobora gufasha kugabanya no kongera ubudahangarwa bw'urusaku n'ubudahangarwa bw'irangi ryo hasi. Byongeye kandi, igiti cyo hagati gishobora kandi kugenzura ubugari n'ubwiza bw'ubutaka bwose, kunoza ubudahangarwa bw'irangi ryo hasi, no kongera ubuzima bw'ubukorano bw'ubutaka.
Igipimo cyo hejuru cy’igitambaro muri rusange ni cyo cyo hejuru, ahanini kigira uruhare mu gushariza no kurinda. Dukurikije ibyo dukeneye bitandukanye, dushobora guhitamo ibikoresho bitandukanye n’ikoranabuhanga nko gusiga irangi rigororotse, ubwoko bwo kwipima, ubwoko bwo kudaserera, umucanga udashira cyane n’umucanga w’amabara kugira ngo tugere ku ngaruka zitandukanye. Byongeye kandi, igipimo cyo hejuru cy’igitambaro gishobora kongera ubukana no kudashira kw’irangi ryo hasi, gukumira imirasire ya UV, ndetse kikagira uruhare runini nko kurwanya no kurwanya ingese.
