Polyurethane adhesives e masani lava ona faasino i mea faʻapipiʻi o loʻo i ai vaega o le carbamate (-NHCOO-) poʻo vaega isocyanate (-NCO) e fai ma mea autu. Polyurethane solvent-based adhesive e faatatau i le faʻaogaina o le solvent e pei o se faʻasalalauga faʻapipiʻi polyurethane, e masani ona faʻaaogaina solvents o ketones, esters, alkanes, benzene, ma isi. gaioiga, ma e iai uiga faʻapipiʻi sili ona lelei ma le tele o meafaitino, e mafua ai le malosi faʻapipiʻi malosi. E i ai le tele o faʻaoga i mea seevae, ie, fafie, lomitusi, puipuiga o le afi ma isi pisinisi.
Miracll amata ona atiina ae, suʻesuʻe ma gaosia polyurethane solvent-based adhesives talu mai lona faʻavaeina i le 2009, ina ua maeʻa le silia ma le 10 tausaga o atinaʻe, ua faʻatupuina le faʻapipiʻi i totonu.ituaiga polyester, ituaiga polycaprolactone, fa'asologa o alifama isi lapopoa ma laiti toetoe lava 20 togi o oloa. Atina'e oloa ma optimization mo alamanuia eseese ma faatinoga manaomia, e mafai ona latou ausia manaoga tagata faatau mo eseesemea fa'apipi'i, pa'u malosi, faiga solvent, itula tatalama faapena atu ai lava.
