2,2-Dimethylolbutanoic acid (DMBA) inonzi neopentyl carboxylic acid ine maviri reactive hydroxymethyl mapoka, saka inogona kushandiswa seyakagadzirwa mvura-based polymer system uye inoshandiswa zvakanyanya mumvura-soluble polyurethane, polyester uye epoxy resin system.
DMBA ine solubility iri nani paneDMPAmune zvakasiyana-siyana zvinonyungudutsa, saka zvinogona kuvandudza zvakanyanya kushanda zvakanaka.
DMBA inoonekwa sechizvarwa chitsva chegirini & nharaunda-inoshamwaridzika cheni extender uye yemukati emulsifier yemvura-yakavakirwa polyurethane; Inogona kushandiswa mukugadzira aqueous polyurethane adhesives pasina kushandisa organic solvents uye kupa zero organic residues. Inogadzirisa zvikanganiso zveDMPAsenge yakakwira kunyungudika, kunonoka kunyungudika, nguva refu yekuita, kushandiswa kwesimba kwakawanda, kuita kwakashata kwechigadzirwa, kudiwa kweorganic solvents, hombe yekunyungudutsa yakasara vhoriyamu zvichingodaro.
Inogona zvakare kushandiswa kugadzira mvura-based epoxy resin uye polyester adhesives.
Parizvino, ndiyo yakanakisa multipurposed modified auxiliary (hydrophilic chain extender) ye polyurethane, mvura-based resins, mvura-based adhesives, mvura-based pendi uye zvimwe zvigadzirwa zvemvura; semonomer yekugadzirisa, Dimethylolbutanoic acid ( DMBA) haidi organic solvents (mvura pachinzvimbo), saka maitiro ekugadzira ari nyore uye ane yakagadzikana uye yakanyanya kuita. Zvikuru,DMPA(dimethylolpropionic acid) ikozvino yave inonyanya kufarirwa chigadzirwa mumunda wemvura-wakavakirwa pakuita kwakanakisa mutengo!
25kg / bhegi; aluminium epurasitiki yefirimu bhegi rakaiswa makadhibhokisi dhiramu kana katoni. 25kg / chigubhu.
