AgeSin®SPA-DHPS 是一款 dihydroxy-type 水性体系 polyurethane chain extender, 具有 sulfonic acid 作为 its primary hydrophilic group. When incorporated into the PU backbone, it contributes to 卓越的 dispersion, 低 required 用量, stable emulsion 储存,及improved 外观. Compared to mainstream products like DMPA (2,2-dimethylolpropionic acid,Cas No 4767-03-7)及DMBA (2,2-dimethylolbutyric acid,Cas No 10097-02-6 ), DHPS exhibits better solubility 于 various solvents及具有 distinct advantages 于 producing 高-solid-content 水性体系 polyurethanes.
