Dipropylene Glycol Methyl Ether (DPM / DPGME)
CAS Number: 34590-94-8
Dipropylene glycol methyl ether (DPM, ≥99.0%) is a high-boiling P-series glycol ether with very slow evaporation, excellent resin solvency, and complete water miscibility. It is widely used as a coalescing aid in architectural and industrial waterborne coatings, industrial cleaners, and as a coupling solvent in water-based formulations requiring extended open time.
