Transparent Colorless Polyethylene Glycol Dimethyl Ether Polyether Solvent CAS:24991-55-7
Polyethylene Glycol Dimethyl Ether (NHD) is a family of methyl-terminated polyethylene glycol ether compounds. Its molecular structure contains repeating –CH₂CH₂O– units and ether groups, while molecular weight, viscosity, boiling characteristics and solubility vary with the degree of polymerization.
With its ether functionality, polarity and compatibility with various organic and polar components, PEG Dimethyl Ether can be used in solvent systems, chemical synthesis, polymer processing, coatings and inks, and specialty chemical formulations. Product selection should be based on molecular weight, viscosity, solubility and specific operating conditions.

DPDM is a slow-evaporating glycol ether solvent with strong solvency and excellent coupling ability, widely used in:
- Coatings & Paints - Coalescing solvent in waterborne coatings; solvent in industrial and automotive finishes
- Industrial Cleaning - Key ingredient in degreasers, paint strippers, and precision parts/electronics cleaners
- Printing Inks - Solvent and viscosity regulator for gravure, flexo, and screen inks
- Agriculture - Solvent/co-solvent in pesticide and herbicide formulations
- Electronics - Solvent for photoresist stripping and wafer cleaning in semiconductor manufacturing
- Brake Fluids - Component in DOT 3/DOT 4 brake fluid formulations
Widely used in paint, cleaning agents, ink, leather and other applications. Can be used instead of alcohol solvents such as ethylene glycol butyl ether during dye dissolution processes. Also used as coating film forming additives, sensitive adhesive, PS version cleaning, printing, electronic chemicals, jet fuel additives (water repellent), extraction solvent and high boiling point solvents.
