Dipropylene Glycol Monomethyl Ether Acetate (DPMAc) is a slow-evaporating, high-boiling glycol ether ester produced by the acetylation of dipropylene glycol monomethyl ether (DPM).
It is widely used as a solvent, coalescent, and coupling agent in coatings, inks, cleaners, and electronics applications because of its excellent solubility and compatibility with polar and non-polar materials.
DPMAc is part of the propylene glycol ether family and is valued for its low odor, moderate evaporation rate, and high solvency for resins and polymers.
