Full Description

Propylene glycol methyl ether is a P-series glycol ether solvent with both water and organic solubility. It is used chiefly in lacquers, paints, printing inks and cleaning formulations, where it dissolves cellulose nitrate and ethers, acrylics, dyes and resins and improves pigment wetting and flow. Further applications include electronics processing and leather finishing, and it serves as a solvent in waterborne and solvent-borne coatings.

Frequently Asked Questions

What is propylene glycol methyl ether used for?

Propylene glycol methyl ether (PGME/PM, CAS 107-98-2, 1-methoxy-2-propanol) is a fast-evaporating glycol-ether solvent. It is widely used in paints, coatings, inks, cleaners, and as a coupling solvent in waterborne and solvent-borne systems.

What is another name for propylene glycol methyl ether?

It is also known as 1-methoxy-2-propanol, PGME, PM, or methoxypropanol (CAS 107-98-2). The shipping name under UN 3092 is 1-methoxy-2-propanol. Specify by CAS to distinguish it from related glycol ethers.

Is propylene glycol methyl ether the same as PGMEA?

No. PGME (CAS 107-98-2) is the ether alcohol, while PGMEA/PMA (CAS 108-65-6) is its acetate ester, which evaporates more slowly. They are different solvents with different evaporation rates; confirm the CAS on the CoA.

Is propylene glycol methyl ether flammable, and how does it ship?

PGME is a flammable liquid transported under UN 3092 (1-methoxy-2-propanol). Review the SDS for the flash point and GHS classification before storage and handling.

What is the price of bulk propylene glycol methyl ether?

RawSource prices PGME by volume and packaging (drums, IBC totes, or bulk) for coatings and cleaning manufacturers rather than a fixed list price. Submit your target quantity and grade for a bulk quote, with a CoA and SDS per lot.
