Aside 2,2-Dimethylolbutanoic (DMBA) ni aside karubokisilike ya neopenteyl ifite amatsinda abiri ya hydroxymethyl, bityo ishobora gukoreshwa nk'uburyo bwa polymeri bushingiye ku mazi kandi ikoreshwa cyane muri polyurethane, polyester na epoxy resin ishongera mu mazi.
DMBA ifite ubushobozi bwo gushonga neza kurusha DMPA mu bintu bitandukanye bishongesha, bityo bishobora kongera cyane imikorere myiza.
DMBA ifatwa nk'ubwoko bushya bw'umuyoboro w'icyatsi kibisi kandi urinda ibidukikije hamwe n'umuyoboro w'imbere wa polyurethane ishingiye ku mazi; Ishobora gukoreshwa mu gukora kole za polyurethane zikoresha amazi zidakoresheje imiti ihumanya ikirere kandi nta bisigazwa bya organic bihari. Ikemura ibibazo bya DMPA nko gushonga cyane, gushonga buhoro buhoro, kumara igihe kirekire ubikora, gukoresha ingufu nyinshi, imikorere mibi y'ibicuruzwa, gukenera imiti ikomoka ku bimera, ingano nini y'ibisigazwa by'imiti n'ibindi.
Ishobora kandi gukoreshwa mu gukora epoxy resin na polyester adhesives bishingiye ku mazi.
Muri iki gihe, ni yo assistant nziza yahinduwe (hydrophilic chain extender) igizwe na polyurethane, resins zishingiye ku mazi, kole ishingiye ku mazi, amarangi ashingiye ku mazi n'ibindi bicuruzwa bikomoka ku mazi; nk'ikintu cyo guhindura ibintu, aside Dimethylolbutanoic (DMBA) ntikeneye organic solvents (amazi ahubwo ikeneye), bityo inzira yo kuyikora yoroshye kandi ifite imikorere ihamye kandi myiza. Cyane cyane, DMPA(aside dimethylolpropionic) ubu yabaye ikintu gikunzwe cyane mu bijyanye n'amazi kubera umusaruro mwiza w'ibiciro!
