2,2-Dimethylolbutanoic acid (DMBA) ndi neopentyl carboxylic acid yokhala ndi magulu awiri a hydroxymethyl, kotero ingagwiritsidwe ntchito ngati ma polymer opangidwa ndi madzi ndipo imagwiritsidwa ntchito kwambiri mu polyurethane, polyester ndi epoxy resin system yosungunuka m'madzi.
DMBA ili ndi kusungunuka bwino kuposa DMPA mu zosungunulira zosiyanasiyana, kotero zimatha kupititsa patsogolo kwambiri magwiridwe antchito.
DMBA imaonedwa ngati mbadwo watsopano wa chowonjezera unyolo chobiriwira komanso chosamalira chilengedwe komanso chotulutsa mkati cha polyurethane chochokera m'madzi; Itha kugwiritsidwa ntchito popanga zomatira za polyurethane zamadzi popanda kugwiritsa ntchito zosungunulira zachilengedwe komanso yopanda zotsalira zachilengedwe. Imathetsa mavuto a DMPA monga kutentha kwambiri, kusungunuka pang'onopang'ono, nthawi yayitali yochitira zinthu, kugwiritsa ntchito mphamvu zambiri, kusagwira bwino ntchito kwa zinthu, kufunikira kwa zosungunulira zachilengedwe, kuchuluka kwakukulu kwa zosungunulira ndi zina zotero.
Ingagwiritsidwenso ntchito popanga utomoni wa epoxy ndi zomatira za polyester zochokera m'madzi.
Pakadali pano, ndi chida chabwino kwambiri chosinthira zinthu zambiri (hydrophilic chain extender) cha polyurethane, ma resins ochokera m'madzi, zomatira zochokera m'madzi, utoto wochokera m'madzi ndi zinthu zina zochokera m'madzi; monga monomer ya njira yosinthira, Dimethylolbutanoic acid (DMBA) sifunikira zosungunulira zachilengedwe (m'malo mwake madzi), chifukwa chake njira yopangira ndi yosavuta ndipo imakhala ndi magwiridwe antchito okhazikika komanso abwino kwambiri. Makamaka, DMPA(dimethylolpropionic acid) tsopano yakhala chinthu chodziwika kwambiri m'munda wamadzi chifukwa cha mtengo wake wabwino kwambiri!
