Diisocyanate (DDI) ke aliphatic diisocyanate e ikhethang e nang le mokokotlo oa 36 carbon atom dimer fatty acid. Sebopeho se fa DDI ho fetoha habonolo le ho khomarela ho feta li-isocyanate tse ling tsa aliphatic. DDI e na le lintho tse nang le chefo e tlase, ha e na mosehla, e qhibiliha ka har'a lihlapolli tse ngata tsa manyolo, ha e na metsi a tlase le viscosity e tlase. DDI ke mofuta oa tšebetso e 'meli ea Isocyanate, e ka sebetsa ka metsoako e 'meli kapa ho feta ea haedrojene e sebetsang ho etsa polymer. DDI e ka sebelisoa ho propellant e tiileng ea rocket, ho qeta lesela, pampiri, letlalo le lesela la lesela, phekolo ea ho boloka lehong, ho pitsa ka motlakase le ho lokisa thepa e khethehileng ea polyurethane (urea) elastomers, sekhomaretsi le sealant, joalo-joalo.

Indastering ea masela, DDI e bonts'a tebello e ntle ea ts'ebeliso ho thepa e thibelang metsi le ho nolofatsa masela. Ha e utloele metsi haholo ho feta li-isocyanate tse nkhang hamonate 'me e ka sebelisoa ho lokisa li-emulsion tse tsitsitseng tsa metsi.

Tšebeliso ea 0.125% DDI e fa lesela le bonolo le tšoarellang; Masela a tšoaroang ka li-softeners tse sa tsitsang tsa cationic a na le maemo a tšoanang ka mor'a ho hlatsoa ha 26. Lesela le lelekang metsi le sebelisang 1%DDI le na le phello e ts'oanang kapa e betere ea ho leleka metsi joalo ka mafura a pyridine water repellent (teko ea AATCC).

DDI e ka ntlafatsa phello ea ho thibela metsi le ho thibela oli bakeng sa masela a fluorinated. Ha e sebelisoa e kopane, DDI e ka ntlafatsa haholo thepa ea masela e thibelang metsi le oli.

Ka bobeli litlhahlobo tsa laboratori le masimo li bonts'itse hore DDI e na le khanyetso e ntle ea ho hlatsuoa le ho omisa ho feta li-fluoride kapa li-additives tsa masela joalo ka li-antistatic agents.

DDI, e lokisitsoeng ho tloha dimer fatty acids, ke mofuta o tloaelehileng oa isocyanate o motala, o ka nchafatsoang ka likokoana-hloko. Ha ho bapisoa le universal isocyanate TDI, MDI, HDI le IPDI, DDI ha e chefo ebile ha e hlasimolle. Ka botumo ba lisebelisoa tse tala tsa dimeric acid Chaena le tlhokomelo e ntseng e eketseha ea batho ho moruo o fokolang oa carbon tikoloho le nts'etsopele e tsitsitseng, bohlokoa ba ho sebelisa lisebelisoa tse tala tse ka nchafatsoang ho lokisoa DDI butle-butle bo hlahile, bo nang le bohlokoa ba bohlokoa bo sebetsang bakeng sa ho khothalletsa nts'etsopele ea indasteri ea polyurethane.
