Ko te waikawa 2,2-Dimethylolbutanoic (DMBA) he waikawa neopentyl carboxylic me nga roopu hydroxymethyl reactive e rua, na reira ka taea te whakamahi hei punaha polymer wai-wai-wai me te whakamahi whanui i roto i te wai-wairewa polyurethane, polyester me te punaha epoxy resin.
He pai ake te whakarewatanga o te DMBADMPAi roto i nga whakarewa rereke, na reira ka tino pai ake te pai o te mahi.
Ko te DMBA ka kiia he reanga hou mo te whakawhanui mekameka kaakaariki me te taiao-hoa me te whakaemulsifier o roto mo te polyurethane e pa ana ki te wai; Ka taea te whakamahi i roto i te hanga o te wai aqueous polyurethane adhesives me te kore e whakamahi i nga whakarewa pararopi me te tuku i nga toenga waro kore. Ka whakatau i nga he oDMPApenei i te rewa teitei, te puhoi te whakakore, te roa o te tauhohenga, te nui o te whakapau kaha, te ngoikore o te mahi hua, te hiahia o nga whakarewa pararopi, te nui o te whakarewatanga o te toenga me etahi atu.
Ka taea hoki te whakamahi mo te hanga i te kapia epoxy e pa ana ki te wai me nga taapiri polyester.
I tenei wa, ko te tino pai rawa atu o nga awhina whakarereke (hydrophilic chain extender) o te polyurethane, te wai-wai-wai, te whakapiri wai-wai, te peita wai-wai me etahi atu hua-wai; hei monomer mo te tukanga whakarereke, waikawa Dimethylolbutanoic ( Ko te DMBA) karekau he whakarewa pararopi (he wai hei utu), na reira he ngawari ake te mahi whakangao me te whai mana me te mahi pai ake. Ina koa,DMPA(waikawa dimethylolpropionic) inaianei kua waiho hei hua tino rongonui i roto i te mara wai-wai mo nga mahi utu pai!
