Dimethylolpropionic acid (DMPA) is a hydroxy acid compound that possesses unique reactive properties owing to the presence of two ester-link carboxyl groups and a hydroxyl group. It is used as a crosslinking agent in the production of coatings, adhesives, and composites. DMPA enhances the overall performance of the final product by improving water resistance, hardness, and binding strength. Its low volatility and high reactivity make it an ideal substitute for formaldehyde-based resins.
