| Applications |
DMBA is a unique multifunctional hindered diol molecule with both hydroxyl and carboxyl groups. It has better solubility than DMPA in various solvents. As a chain extender and hydrophilic agent, DMBA has been widely used in the production of waterborne coatings, adhesives, and leather finishes in waterborne polyurethane systems. |
