Propylene Glycol Monomethyl Ether
Propylene Glycol Monomethyl Ether (PGME) is produced by a reaction of propylene oxide with methanol using a catalyst. This reaction produces a clear, colorless liquid with an ether-like odor that spreads over distance. The properties of this compound include moderate volatility, moderate flammability and stability. Also, this chemical is soluble in water, methanol, ether and other organic solvents. The low systemic toxicity of PGME increases the attractiveness of this chemical.
Uses for this chemical vary widely. PGME is primarily used as a solvent for cellulose, acrylics, dyes, inks and stains. Therefore, paints and lacquers are a prime use. PGME helps produce propylene glycol methyl ether acetate (PMA) by acting as a chemical building block. Many industrial, chemical, automotive and household cleaners include PGME as well. Other applications include use as a coalescing agent in coatings and electronics. Household applications abound including floor polish, caulking and sealants, pesticides, dyes, and inks.
