RE ea rona, eo hape e bitsoang TTI, ke tharollo e nang le 27.5% triphenylmethane-4,4ˊ,4〞-triisocyanate le 72.5% ethyl acetate. Ke sekhomaretsi sa bokahohleng bakeng sa sekhomaretsi se thehiloeng ho hydroxyl polyurethane, liraba tsa tlhaho le tsa maiketsetso, tse ntle haholo bakeng sa ho kopanya thepa ea rabara. E boetse e sebelisoa haholo bakeng sa ho kopanya litšepe le rabara. Ho feta moo, RE e ka sebelisoa ho resin, antioxidant, plasticizer, joalo-joalo Lefapheng la sekhomaretsi, RE e sebelisoa e le motsoako oa crosslinking holim'a sekhomaretsi sa neoprene le / kapa p hydroxyl polyurethane adhesive libakeng tsa lieta. Ka kakaretso, bakeng sa ho phekola sekhomaretsi sa likarolo tse 100 ka boima ba 'mele (pbw) ho latela palo e khothaletsoang ea 4-7 pbw RE. Bophelo ba pitsa ea sekhomaretsi se tsoakiloeng ke lihora tse ka bang teng.
Sekhomaretsi sa likarolo tse peli se tlameha ho sebelisoa ka nako e loketseng ka mor'a ho kenya RE. Bolelele ba nako e sebetsang ha bo amane feela le sekhomaretsi sa polymer, empa le likarolo tse ling tse amehang (joalo ka resin, antioxygen, plasticizer, solvent, joalo-joalo. e ba thata haholoanyane ho sebetsa, 'me viscosity ea phahama haufinyane, E fetoha sekhomaretsi sa boleng ba 100, Hydroxyl polyurethane (Polyurethane account bakeng sa hoo e ka bang 20%), RE lethal dose ea 4-7. , RE ea rona e etsa 4-7.
