Tapanga dimer acid diisocyanate (DDI) yapoizoni yotsika pogwiritsa ntchito zida zongowonjezeranso zachilengedwe komanso ukadaulo waukadaulo poyankha kawopsedwe kambiri ka ma isocyanate omwe amagwiritsidwa ntchito kwambiri pamsika wapanyumba komanso kuvulaza kwambiri thupi la munthu.Zizindikiro zafika pamlingo wankhondo waku US (MIL-STD-129).Molekyu ya isocyanate ili ndi tcheni lalitali la 36-carbon dimerized fatty acid, ndipo ndi lamadzimadzi kutentha.Ili ndi zabwino zambiri monga kawopsedwe kakang'ono, kugwiritsa ntchito bwino, kusungunuka mu zosungunulira zambiri, nthawi yosinthika komanso kukhudzika kwamadzi pang'ono.Ndi mtundu wobiriwira wa isocyanate wobiriwira wobiriwira, womwe ungagwiritsidwe ntchito kwambiri m'magulu ankhondo ndi anthu wamba monga kumaliza kwa nsalu, ma elastomer, zomatira ndi zosindikizira, zokutira, inki, ndi zina zambiri.
