Dipropylene Glycol Methyl Ether Acetate (DPMA)

Dipropylene Glycol Methyl Ether Acetate (DPMA), identified by CAS number 88917-22-0, is a high-boiling, slow-evaporating glycol ether acetate characterized by its exceptional solvency and low volatility. As a prominent member of the P-series glycol ether family, it serves as a technically superior and toxicologically safer alternative to many ethylene oxide-based (E-series) solvents. DPMA is a clear, colorless liquid with a mild, non-intrusive ether-like odor, making it highly desirable for applications where worker comfort and sensory impact are critical.

Chemically, DPMA combines the functional properties of an ether and an ester, resulting in a hydrophobic character that facilitates the efficient dissolution of various synthetic resins, including acrylics, epoxies, polyurethanes, and alkyds. Its primary industrial utility lies in its role as a “tail solvent” and coalescing agent. It is specifically engineered to enhance film formation, improve flow and leveling, and prevent surface defects such as blushing or orange peel in high-performance coating systems.
