I-2,2-Dimethylolbutanoic acid (DMBA) iyi-neopentyl carboxylic acid enamaqembu amabili e-reactive hydroxymethyl, ngakho-ke ingasetshenziswa njengezinhlelo ze-polymer ezisekelwe emanzini futhi isetshenziswa kabanzi ohlelweni lwe-polyurethane oluncibilika emanzini, i-polyester kanye ne-epoxy resin.
I-DMBA inokuncibilika okungcono kune- I-DMPA ezincibilikisini ezahlukene, ngakho-ke kungathuthukisa kakhulu ukusebenza kahle.
I-DMBA ibhekwa njengesizukulwane esisha se-chain extender eluhlaza futhi enobungani nemvelo kanye ne-emulsifier yangaphakathi ye-polyurethane esekelwe emanzini; Ingasetshenziswa ekukhiqizeni izinamathiselo ze-polyurethane zamanzi ngaphandle kokusebenzisa izinyibilikisi eziphilayo futhi ayinikezi zinsalela eziphilayo. Ixazulula amaphutha e- I-DMPA njengephuzu eliphezulu lokuncibilika, ukuncibilika okuhamba kancane, isikhathi eside sokuphendula, ukusetshenziswa kwamandla aphezulu, ukusebenza kabi komkhiqizo, isidingo sezinyibilikisi eziphilayo, ivolumu enkulu yensalela yesinyibilikisi njalo njalo.
Ingasetshenziswa futhi ekukhiqizeni i-epoxy resin kanye ne-polyester adhesives ezisekelwe emanzini.
Njengamanje, iyi-assistant modified assistant engcono kakhulu enezinhloso eziningi (hydrophilic chain extender) ye-polyurethane, ama-resin asekelwe emanzini, izinamathiselo ezisekelwe emanzini, upende olusekelwe emanzini kanye neminye imikhiqizo esekelwe emanzini; njenge-monomer yenqubo yokuguqulwa, i-Dimethylolbutanoic acid (DMBA) ayidingi izinyibilikisi eziphilayo (esikhundleni samanzi), ngakho-ke inqubo yokukhiqiza ilula futhi inokusebenza okuzinzile nokusebenza okuhle kakhulu. Ikakhulukazi, I-DMPA(i-dimethylolpropionic acid) manje isibe umkhiqizo othandwa kakhulu emkhakheni osekelwe emanzini ngenxa yokusebenza kahle kwezindleko!
