Propylene glycol methyl ether acetate

Propylene glycol methyl ether acetate (CAS 108-65-6), commonly sourced and specified as PGMEA or methoxypropyl acetate, is a slow-evaporating ester solvent used across coatings, electronics, and printing industries.

Its controlled evaporation rate supports film formation and flow in high-performance formulations where solvent balance is critical to end-product quality. In architectural and industrial coatings, it functions as a coalescing solvent.

It acts as a viscosity modifier, improving leveling and film integrity in both solvent-borne and high-solids systems. Semiconductor and PCB manufacturers rely on it as a carrier solvent for photoresists and anti-reflective coatings.

In these high-tech applications, purity specifications are tightly controlled to ensure performance. In printing inks, particularly UV-curable and gravure formulations, it dissolves resins and controls ink rheology to meet press requirements.

Adhesive and sealant formulators use it to adjust open time and application viscosity in structural and pressure-sensitive systems. This versatility makes it a staple in modern chemical manufacturing and industrial processing.

PGMEA is supplied as a clear liquid in drum, IBC, and bulk tanker quantities. Electronic-grade and standard technical-grade are the primary commercial specifications available for various industrial needs.

Electronic-grade material carries tighter purity and metals content requirements for semiconductor applications. Standard technical-grade material is available for coatings, inks, and adhesive end uses across the global market.
