What is Ethylene glycol monomethyl ether?
Ethylene glycol monomethyl ether (CAS 109-86-4), also known as Methyl Glycol or EGME, is a slow-evaporating glycol ether solvent.
Where is Ethylene glycol monomethyl ether used?
- Industrial coatings and lacquers: improves flow, leveling, and film uniformity, reducing surface defects in spray and brush applications
- Printing inks: controls drying speed and maintains viscosity stability in solvent and water-reducible systems
- Adhesives and sealants: carrier solvent aiding resin dissolution and extending open time
- Polymer and resin production: reactive diluent or curing co-solvent in epoxy and nitrocellulose-based systems
- Its controlled evaporation rate and compatibility with water-based and solvent-based systems support film formation and flow during production.
Good to know: Buyers should confirm purity, water content, and acidity specifications against their formulation or process requirements. Proper storage and handling are essential for maintaining chemical integrity.
Commercial specifications
- Technical grade, purity typically 99% or higher
- Clear liquid in drum, IBC, and bulk quantities
