2,2-Dimethylolbutanoic acid (DMBA) iasidhi ye neopentyl carboxylic ine mapoka maviri ehydroxymethyl, saka inogona kushandiswa semasystem epolymer akagadzirwa nemvura uye inoshandiswa zvakanyanya mu polyurethane, polyester uye epoxy resin system inonyungudika mumvura.
DMBA ine kunyungudika kuri nani pane DMPA muzvinhu zvakasiyana-siyana zvinonyungudutsa, saka zvinogona kuvandudza kushanda zvakanaka kwekushanda.
DMBA inoonekwa sechizvarwa chitsva che chain extender ine green uye nharaunda uye emulsifier yemukati ye polyurethane inogadzirwa nemvura; Inogona kushandiswa mukugadzira adhesives ye polyurethane yemvura pasina kushandisa organic solvents uye isina organic residues. Inogadzirisa zvikanganiso zve DMPA zvakaita senzvimbo yekunyunguduka kwakanyanya, kunyunguduka kunonoka, nguva yakareba yekuita chimwe chinhu, kushandiswa kwesimba rakawanda, kushanda zvisina kunaka kwechigadzirwa, kudiwa kwezvinonyungudutsa zve organic, huwandu hwakawanda hwezvinonyungudutsa nezvimwewo.
Inogona zvakare kushandiswa kugadzira epoxy resin nemvura uye polyester adhesives.
Parizvino, ndiyo yakanakisisa inoshandiswa pakugadzira zvinhu zvakawanda (hydrophilic chain extender) yepolyurethane, resins dzinobva mumvura, zvinonamira zvinobva mumvura, pendi dzinobva mumvura nezvimwe zvigadzirwa zvinobva mumvura; semonomer yekuchinja, Dimethylolbutanoic acid (DMBA) haidi organic solvents (mvura pachinzvimbo), saka maitiro ekugadzira ari nyore uye ane simba rakasimba uye rakanakisisa. Kunyanya, DMPA(dimethylolpropionic acid) yava chigadzirwa chinozivikanwa zvikuru mumvura nekuda kwekushanda zvakanaka kwemari!
