Full Description

Dipropylene glycol monomethyl ether (CAS 34590-94-8), or DPM, is a slow-evaporating glycol ether solvent. It is used as a coalescing and coupling solvent in water-based coatings and hard-surface cleaners, as a solvent for nitrocellulose and synthetic resins, and in hydraulic fluids.

Frequently Asked Questions

What is dipropylene glycol monomethyl ether (DPM) used for?

DPM is a slow-evaporating glycol ether solvent used as a coalescing and coupling solvent in water-based (latex) coatings and hard-surface cleaners, as a solvent for nitrocellulose and synthetic resins, in hydraulic and brake-fluid formulations, and as a coupling agent in water-based polishes.

What is the difference between DPM and dipropylene glycol dimethyl ether?

DPM is the monomethyl ether (one methyl ether group, one free hydroxyl; CAS 34590-94-8, C7H16O3). The dimethyl ether (proglyde DMM) has both hydroxyls capped and is a different, more aprotic solvent. Confirm the CAS on the CoA to get the correct material.

What is the CAS number and formula of DPM?

CAS 34590-94-8, molecular formula C7H16O3 (a mixture of isomers). It is also sold as DPGME or DPnP-type glycol ether. Identity, isomer profile, and physical properties are documented on the CoA and SDS.

Is DPM the same as its acetate (DPMA)?

No. DPM is the glycol ether alcohol; DPM acetate (DPMA) is the acetate ester, a separate product with different evaporation and solvency. If you need the acetate, specify it on your RFQ and confirm CAS on the CoA.

How is bulk DPM packaged and quoted?

DPM is supplied in drums, totes, or bulk to coatings and cleaner formulators. Pricing depends on volume, packaging, and destination; submit a bulk RFQ with your quantity for a current quote, CoA, and SDS.
