191 polyester idahagije ni resin ikunze gukoreshwa ifite imiterere yumubiri nziza hamwe nubutunzi bwimiti ikoreshwa cyane mubwubatsi, ibinyabiziga, marine, ibikoresho bya elegitoroniki, ibikoresho nibindi bikoresho.
191 polyester idahagije ikorwa na polymerisation reaction ya acide idahagije, inzoga na diluent nibindi bikoresho bibisi. Ifite amazi meza na plastike, kandi irashobora gutunganywa muburyo butandukanye bwibicuruzwa binyuze mu kubumba, kubumba inshinge, gutera no mubindi bikorwa. Muri icyo gihe, ifite kandi uburyo bwiza bwo kurwanya ruswa irwanya ubushyuhe no kurwanya ikirere, irashobora gukoreshwa ahantu habi igihe kirekire.
Mu murima wubwubatsi, 191 ya polyester idahagije ikoreshwa cyane mugukora ibicuruzwa bya FRP, nkibigega byamazi, ibigega byo kubika hamwe nu miyoboro. Ibicuruzwa bifite ibiranga uburemere bworoshye, imbaraga nyinshi, kurwanya ruswa, nibindi, kandi birashobora guhaza inyubako zikenewe mubidukikije. Mu rwego rwimodoka nubwato, resin idahagije 191 polyvinyl acetate resin ikoreshwa mugukora umubiri, hull nibindi bice. Ibi bice biremereye, imbaraga-nyinshi, birwanya ruswa, nibindi, kandi birashobora kunoza imikorere nubuzima bwa serivisi bwimodoka nubwato.
Mu rwego rwa elegitoroniki n'ibikoresho, ibikoresho bya polyester 191 bidahagije bikoreshwa mugukora ibishishwa, imbaho nibindi bice. Ibi bice bifite ubuso bwiza bwo hejuru hamwe no kurwanya abrasion, bishobora guteza imbere isura nubuzima bwa serivisi byibicuruzwa.
191 poliester idahagije ni resinike nziza ya syntetique hamwe nurwego runini rwo gusaba. Hamwe niterambere ryiterambere rya siyanse nikoranabuhanga hamwe no kwaguka kwaguka mubikorwa, bizakoreshwa mubice byinshi.
