2,2-Dimethylolbutanoic acid (DMBA) ndi neopenyl carboxylic acid yokhala ndi magulu awiri otakataka a hydroxymethyl, kotero imatha kugwiritsidwa ntchito ngati makina opangira polima opangidwa ndi madzi ndipo amagwiritsidwa ntchito kwambiri m'madzi osungunuka a polyurethane, polyester ndi epoxy resin system.
DMBA ili ndi kusungunuka kwabwinoko kuposaDMPAmu zosungunulira zosiyanasiyana, kotero izo zikhoza kwambiri kusintha dzuwa ntchito.
DMBA imatengedwa ngati m'badwo watsopano wa green & chilengedwe-wochezeka unyolo extender ndi emulsifier mkati kwa polyurethane madzi-based; Itha kugwiritsidwa ntchito popanga zomatira zamadzimadzi a polyurethane popanda kugwiritsa ntchito zosungunulira za organic ndikupereka zotsalira za ziro. Imathetsa zolakwa zaDMPAmonga malo osungunuka kwambiri, kusungunuka kwapang'onopang'ono, nthawi yayitali yochitapo kanthu, kugwiritsa ntchito mphamvu zambiri, kusagwira ntchito bwino kwa mankhwala, kufunikira kwa zosungunulira organic, voliyumu yayikulu yotsalira ya zosungunulira ndi zina zotero.
Itha kugwiritsidwanso ntchito popanga madzi opangira epoxy resin ndi zomatira za polyester.
Pakalipano, ndi njira yabwino kwambiri yowonjezera yowonjezera yowonjezera (hydrophilic chain extender) ya polyurethane, utomoni wamadzi, zomatira zamadzi, utoto wamadzi ndi zinthu zina zamadzi; monga monomer pakusintha, Dimethylolbutanoic acid ( DMBA) safuna zosungunulira za organic (madzi m'malo mwake), chifukwa chake kupanga kwake ndikosavuta komanso kumakhala kokhazikika komanso kopambana. Makamaka,DMPA(dimethylolpropionic acid) tsopano yakhala chinthu chodziwika kwambiri m'munda wamadzi chifukwa chakuchita bwino kwambiri!
