Twateje imbere acide ya dimer acide diisocyanate (DDI) dukoresheje ibikoresho fatizo bio-ishobora kuvugururwa hamwe nikoranabuhanga rishya mugusubiza uburozi bukabije bwa isocyanate ikoreshwa kumasoko yimbere mugihugu kandi byangiza umubiri.Ibipimo byageze ku rwego rw’igisirikare cy’Amerika (MIL-STD-129).Molekile ya isocyanate irimo 36-karubone dimerized fatty acide, kandi itemba mubushyuhe bwicyumba.Ifite ibyiza byinshi nkuburozi buke, gukoresha byoroshye, gushonga mumashanyarazi menshi, kugenzurwa nigihe cyo gufata amazi hamwe no kumva neza amazi.Nubwoko busanzwe bwatsi-bushobora kuvugururwa butandukanye bwa isocyanate, bushobora gukoreshwa cyane mubikorwa bya gisivili nabasivili nko kurangiza imyenda, elastomers, ibifunga hamwe na kashe, impuzu, wino, nibindi.
