What is Propylene glycol dimethyl ether?
Propylene glycol dimethyl ether (CAS 7778-85-0), also known as 1,2-dimethoxypropane, is a low-viscosity ether solvent.
Where is Propylene glycol dimethyl ether used?
- Electronics: precision cleaning solvent for flux removal and surface preparation of PCBs
- Printing inks and packaging coatings: co-solvent controlling viscosity and drying speed
- Automotive refinishing and underbody coatings: improves flow and reduces application defects
- Home care and industrial cleaning concentrates: boosts solvency of active ingredients against greases and hydrocarbon soils
- It acts as a fast-evaporating carrier in residue-free formulations.
Commercial specifications
- Purity typically 99% and up
- COA and GC purity confirmation from most suppliers
- Drum and IBC quantities; bulk tanker options
