I-2,2-Dimethylolbutanoic acid (DMBA) yi-neopentyl carboxylic acid enamaqela amabini e-reactive hydroxymethyl, ngoko ke ingasetyenziswa njengeenkqubo ze-polymer ezisekelwe emanzini kwaye isetyenziswa kakhulu kwinkqubo ye-polyurethane enyibilikayo emanzini, i-polyester kunye ne-epoxy resin.
I-DMBA inokunyibilika okungcono kune I-DMPA kwiinyibilikisi ezahlukeneyo, ngoko ke inokuphucula kakhulu ukusebenza kakuhle.
I-DMBA ithathwa njengesizukulwana esitsha se-chain extender eluhlaza kunye nokusingqongileyo kunye ne-emulsifier yangaphakathi ye-polyurethane esekwe emanzini; Ingasetyenziswa ekuveliseni izincamathelisi ze-polyurethane zamanzi ngaphandle kokusebenzisa izinyibilikisi ze-organic kwaye ayinazo iintsalela ze-organic. Isombulula iingxaki ze I-DMPA ezifana nendawo yokunyibilika ephezulu, ukunyibilika kancinci, ixesha elide lokuphendula, ukusetyenziswa kwamandla aphezulu, ukusebenza kakubi kwemveliso, isidingo se-organic solvents, ubungakanani obukhulu be-solvent residue njalo njalo.
Ingasetyenziselwa ukwenziwa kwee-epoxy resin kunye nee-polyester adhesives ezisekelwe emanzini.
Okwangoku, yeyona ndlela ingcono kakhulu yokuncedisa eguqulweyo eneenjongo ezininzi (i-hydrophilic chain extender) ye-polyurethane, ii-resin ezisekelwe emanzini, izincamathelisi ezisekelwe emanzini, iipeyinti ezisekelwe emanzini kunye nezinye iimveliso ezisekelwe emanzini; njenge-monomer yenkqubo yokuguqula, i-Dimethylolbutanoic acid (DMBA) ayifuni zinyibilikisi zendalo (endaweni yoko amanzi), ngoko ke inkqubo yemveliso ilula kwaye ine-stabler kunye nokusebenza okungcono. Ingakumbi, I-DMPA(i-dimethylolpropionic acid) ngoku iyeyona mveliso idumileyo kwicandelo elisekelwe emanzini ngenxa yokusebenza kakuhle kweendleko!
