Diisocyanate (DDI) ndi wapadera aliphatic diisocyanate wokhala ndi 36 carbon atomu dimer fatty acid msana.Kapangidwe kameneka kamapatsa DDI kusinthasintha bwino komanso kumamatira kuposa ma isocyanate ena aliphatic.DDI ili ndi kawopsedwe wochepa, wopanda chikasu, amasungunuka muzosungunulira zambiri za organic, tcheru pamadzi otsika komanso kukhuthala kochepa.DDI ndi mtundu wa machitidwe awiri a Isocyanate, amatha kugwira ntchito ndi ma hydrogen awiri kapena kupitilira apo kuti apange polima.DDI angagwiritsidwe ntchito olimba rocket propellant, nsalu yomaliza, mapepala, zikopa ndi nsalu othamangitsa, nkhuni zosungira mankhwala, potting magetsi ndi kukonzekera katundu wapadera wa polyurethane (urea) elastomers, zomatira ndi sealant, etc.

M'makampani a Nsalu, DDI ikuwonetsa mwayi wogwiritsa ntchito bwino pakuchotsa madzi komanso kufewetsa nsalu.Simamva bwino kwambiri ndi madzi kuposa ma isocyanates onunkhira ndipo imatha kugwiritsidwa ntchito popanga ma emulsions okhazikika amadzimadzi.

Kugwiritsa ntchito 0.125% DDI kumapereka nsalu yofewa yokhazikika;Nsalu zomwe zimagwiritsidwa ntchito ndi zofewa za cationic zimakhala ndi kusinthasintha kofanana pambuyo pa kutsuka 26.Zochotsa madzi pansalu pogwiritsa ntchito 1% DDI zimakhala ndi zotsatira zofanana kapena zabwinoko zothamangitsa madzi ngati mafuta othamangitsa madzi a pyridine (mayeso a AATCC).

DDI ikhoza kupititsa patsogolo mphamvu ya madzi oletsa madzi ndi mafuta opangira nsalu za fluorinated.Akagwiritsidwa ntchito pamodzi, DDI ikhoza kupititsa patsogolo kwambiri nsalu zopanda madzi komanso mafuta.

Kuwunika kwa labotale ndi kumunda kwawonetsa kuti DDI imakana bwino kutsuka ndi kutsuka kowuma kuposa zowonjezera za fluoride kapena nsalu monga antistatic agents.

DDI, yokonzedwa kuchokera ku dimer fatty acids, ndi mtundu wobiriwira, wosasinthika wa isocyanate.Poyerekeza ndi Universal isocyanate TDI, MDI, HDI ndi IPDI, DDI ndi yopanda poizoni komanso yosalimbikitsa.Ndi kutchuka kwa dimeric asidi zopangira mu China ndi anthu akuchulukirachulukira otsika mpweya chitetezo zachilengedwe chuma ndi chitukuko zisathe, kufunika kwa kugwiritsa ntchito bio-zongowonjezwdwa zopangira kukonzekera DDI wakhala pang'onopang'ono anatulukira, amene ali ndi zofunika zothandiza zothandiza kulimbikitsa chitukuko cha mafakitale a polyurethane.
