Propylene Glycol Methyl Ether (PM / 1-Methoxy-2-propanol)
CAS Number: 107-98-2
Propylene glycol methyl ether (PM, ≥99.5%) is a glycol ether solvent with excellent solvency for a wide range of resins and full water miscibility, making it a preferred co-solvent in waterborne coatings, inks, and cleaning products. Its low toxicity profile (P-series glycol ether) and coupling ability make it superior to ethylene glycol ethers in many applications.
