Peb tau tsim cov tshuaj lom neeg tsis muaj tshuaj lom dimer acid diisocyanate (DDI) los ntawm kev siv bio-renewable raw cov ntaub ntawv thiab cov thev naus laus zis tshiab hauv kev teb rau cov tshuaj lom neeg uas nquag siv isocyanates hauv kev ua lag luam hauv tsev thiab kev puas tsuaj loj rau tib neeg lub cev.Cov ntsuas tau mus txog qib ntawm US tub rog tus qauv (MIL-STD-129).Lub isocyanate molecule muaj 36-carbon dimerized fatty acid ntev saw, thiab yog kua nyob rau hauv chav tsev kub.Nws muaj ntau yam zoo xws li tsis tshua muaj toxicity, yooj yim siv, soluble nyob rau hauv feem ntau cov kuab tshuaj, tswj lub sij hawm tshuaj tiv thaiv thiab tsis tshua muaj dej rhiab heev.Nws yog ib hom ntsuab bio-renewable tshwj xeeb isocyanate ntau yam, uas tuaj yeem siv dav hauv kev ua tub rog thiab pej xeem xws li ntaub xov, elastomers, adhesives thiab sealants, coatings, inks, thiab lwm yam.
