APPLICATIONS |
||
| Polyol and carboxyl acid are essential in polyurethane manufacturing system. Dimethylol butanoic acid (DMBA) contains two kinds of functional groups in one molecule. There are two primary hydroxyl groups and one tertiary carboxyl group which provide function of making polyurethanes and polyesters especially water soluble. DMBA is known to have better solubility in ketone solvents than its analogue , dimethylol propionic acid. Application includes polyurethane dispersion, alkyds and polyesters, chemical building block, printing inks, photographic chemicals. | ||
