Ethylene Glycol Monomethyl Ether (EGME) uses
CAS 109-86-4 Ethylene Glycol Monomethyl Ether has a high solvent power and is often used with low-boiling solvents. Methyl Cellosolve (Methyl Glycol) is used in cellulose acetate and cellulose ether lacquers. It has a high boiling point, but its evaporation rate is high, allowing for rapid film formation. It is a good solvent for nitrocellulose, making highly concentrated lacquer solutions that dry and set quickly. It can be used to adjust the evaporation time and flow of cellulose ether lacquers. It can be diluted with toluene or ethanol for this.
