Is DPM the same as propylene glycol monomethyl ether (PGME)?

No. DPM contains an additional propylene-oxide unit and is normally selected where a slower-evaporating glycol ether is needed. Confirm the intended resin system and evaporation profile rather than substituting it directly for PGME.

Can DPM be used in waterborne coating systems?

DPM is water-miscible and is used as a coalescent or solvent in many waterborne systems. Compatibility and the final evaporation balance should be evaluated with the complete resin, pigment and additive package.

Which DPM specification points should be confirmed before use?

Confirm assay, water content, colour, required packing and any application-specific restriction. The batch COA should be reviewed against the agreed specification before the material is introduced into production.

Dipropylene Glycol Monomethyl Ether (DPM) CAS 34590-94-8

Dipropylene Glycol Monomethyl Ether (DPM), CAS 34590-94-8, also known as dipropylene glycol methyl ether, is a slow-evaporating glycol ether solvent for industrial coatings, inks, adhesive and cleaning formulations. 2-Butoxyethanol is a related glycol ether option where a different evaporation and coupling balance is specified. Its water miscibility and controlled evaporation profile are considered alongside resin compatibility and the finished system. COA, TDS and SDS are available for the offered lot; assay, water, colour and packing are confirmed against the required specification.

Product Introduction

Dipropylene Glycol Monomethyl Ether (DPM) (CAS 34590-94-8) is supplied as a slow-evaporating glycol-ether solvent for coating, ink, cleaning and process formulations. We quote DPM by its CAS and grade, not as a generic propylene-glycol ether; it is distinct from PM / 1-methoxy-2-propanol (CAS 107-98-2).

Applications

Industrial coatings, including waterborne, solvent-borne and selected electrodeposition systems.
Printing inks and graphic-arts formulations requiring a slow glycol-ether solvent.
Industrial cleaners, coupling-solvent and selected extraction or process formulations.
Resin and coating manufacture using DPM as a defined solvent component.

Grade and Supply Details

We confirm the required purity, water, acidity, colour, distillation range and stated test method against the intended formulation. DPM is normally offered as a clear liquid in 200 kg drums, 1000 kg IBCs or bulk arrangements. A batch COA, with the applicable TDS and SDS, is available for the offered material.
