ʻO ka 2,2-Dimethylolbutanoic acid (DMBA) he neopentyl carboxylic acid me ʻelua mau hui hydroxymethyl reactive, no laila hiki ke hoʻohana ʻia e like me nā ʻōnaehana polymer wai-synthetic a hoʻohana nui ʻia i ka polyurethane wai-soluble, polyester a me ka ʻōnaehana epoxy resin.
ʻOi aku ka maikaʻi o ka solubility o DMBA ma mua o DMPA i nā mea hoʻoheheʻe like ʻole, no laila hiki ke hoʻomaikaʻi nui i ka pono hana.
Ua manaʻo ʻia ʻo DMBA he hanauna hou o ka mea hoʻolōʻihi kaulahao ʻōmaʻomaʻo a me ke kaiapuni a me ka emulsifier kūloko no ka polyurethane wai; Hiki ke hoʻohana ʻia i ka hana ʻana o nā mea hoʻopili polyurethane wai me ka hoʻohana ʻole ʻana i nā mea hoʻoheheʻe organik a hāʻawi ʻole i nā koena organik. Hoʻoponopono ia i nā hewa o DMPA e like me ke kiʻekiʻe o ka heheʻe ʻana, ka lohi o ka hoʻoheheʻe ʻana, ka manawa pane lōʻihi, ka hoʻohana ʻana i ka ikehu kiʻekiʻe, ka hana huahana maikaʻi ʻole, ka pono o nā mea hoʻoheheʻe organik, ka nui o ke koena o ka mea hoʻoheheʻe a pēlā aku.
Hiki ke hoʻohana ʻia no ka hana ʻana i ka epoxy resin wai a me nā polyester adhesives.
I kēia manawa, ʻo ia ka mea kōkua hoʻololi multipurposes maikaʻi loa (hydrophilic chain extender) o ka polyurethane, nā resins wai, nā mea hoʻopili wai, nā pena wai a me nā huahana wai ʻē aʻe; ma ke ʻano he monomer no ke kaʻina hana hoʻololi, ʻaʻole pono ka Dimethylolbutanoic acid (DMBA) i nā mea hoʻoheheʻe organik (wai ma kahi), no laila ua maʻalahi ke kaʻina hana a loaʻa iā ia ka hana paʻa a maikaʻi loa. ʻOi loa, DMPA(dimethylolpropionic acid) i kēia manawa ua lilo i huahana kaulana loa ma ke kahua wai no ka hana kumukūʻai maikaʻi loa!
