What is Dipropylene glycol monomethyl ether?
Dipropylene glycol monomethyl ether (CAS 20324-32-7), commonly abbreviated as DPM, is a slow-evaporating glycol ether solvent.
Where is Dipropylene glycol monomethyl ether used?
- Coatings: improves flow and leveling in waterborne and solvent-based systems, reducing surface defects during drying
- Electronics: precision cleaning agent and flux carrier with residue-free evaporation
- Printing inks and packaging adhesives: coalescing solvent that extends open time and improves substrate adhesion
- Sealants and adhesives: reactive diluent carrier to control viscosity during application
- It serves as a carrier in formulations where film formation and surface wetting are critical.
Good to know: The commercial product is typically a mixture of isomers; suppliers may specify isomer composition where specific purity requirements demand it.
Commercial specifications
- Clear liquid in drums, IBCs, and bulk tanker quantities
- Technical grade for industrial solvent applications and higher-purity grades
