2,2-Dimethylolbutanoic acid (DMBA) waa neopentyl carboxylic acid oo leh laba kooxood oo hydroxymethyl ah oo falgal ah, sidaa darteed waxaa loo isticmaali karaa nidaamyada polymer-ka ee ku salaysan biyaha ee isku-dhafan waxaana si ballaaran loogu isticmaalaa nidaamka polyurethane, polyester iyo epoxy resin ee biyaha ku milma.
DMBA waxay leedahay milmi ka wanaagsan tan DMPA dareereyaal kala duwan, sidaa darteed waxay si weyn u wanaajin kartaa hufnaanta shaqada.
DMBA waxaa loo arkaa jiil cusub oo fidiye silsilad cagaaran & deegaan u fiican iyo emulsifier gudaha ah oo loogu talagalay polyurethane-ka ku salaysan biyaha; Waxaa loo isticmaali karaa soo saarista dhejisyada polyurethane-ka biyaha lagu dhejiyo iyada oo aan la isticmaalin dareere dabiici ah oo aan bixin haraaga organic-ga eber ah. Waxay xallisaa cilladaha DMPA sida dhibic dhalaalid sare, kala dirid gaabis ah, waqti falcelin dheer, isticmaalka tamarta sare, waxqabadka badeecada oo liita, baahida loo qabo dareere dabiici ah, mugga haraaga dareeraha weyn iyo wixii la mid ah.
Waxa kale oo loo isticmaali karaa soo saarista epoxy resin biyo ku salaysan iyo dhejisyada polyester.
Waqtigan xaadirka ah, waa qalabka ugu wanaagsan ee wax laga beddelay ee loo adeegsado ujeeddooyin badan (fidinta silsiladda hydrophilic) ee polyurethane, resins-ka ku salaysan biyaha, dhejisyada ku salaysan biyaha, rinjiyeyaasha ku salaysan biyaha iyo alaabada kale ee ku salaysan biyaha; sida monomer-ka habka wax-ka-beddelka, Dimethylolbutanoic acid (DMBA) uma baahna dareere dabiici ah (biyo beddelkeeda), sidaa darteed habka wax-soo-saarku waa mid fudud oo leh waxqabad deggan oo ugu fiican. Gaar ahaan, DMPA(dimethylolpropionic acid) hadda waxay noqotay badeecada ugu caansan ee ku jirta biyaha ku salaysan waxqabadka qiimaha aadka u fiican!
