What is Propylene glycol methyl ether acetate?

Propylene glycol methyl ether acetate (CAS 108-65-6), commonly specified as PGMEA or methoxypropyl acetate, is a slow-evaporating ester solvent.

Where is Propylene glycol methyl ether acetate used?

Architectural and industrial coatings: coalescing solvent
Solvent-borne and high-solids systems: viscosity modifier improving leveling and film integrity
Semiconductor and PCB manufacturing: carrier solvent for photoresists and anti-reflective coatings
Printing inks: dissolves resins and controls ink rheology in UV-curable and gravure formulations
Adhesives and sealants: adjusts open time and application viscosity in structural and pressure-sensitive systems
Its controlled evaporation rate supports film formation and flow where solvent balance is critical.

Good to know: Electronic-grade carries tighter purity and metals content requirements for semiconductor applications; standard technical-grade serves coatings, inks, and adhesives.
