Propylene glycol methyl ether acetate

Propylene glycol methyl ether acetate (PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether used in inks, coatings, and cleaners.

It is sold by Dow Chemical under the name Dowanol PMA,[3] by Shell Chemical under the name methyl proxitol acetate,[4][5] and by Eastman under the name PM Acetate.

[6] In the semiconductor industry, PGMEA is a commonly used solvent, primarily for the application of surface adherents such as Bis(trimethylsilyl)amine (HMDS) on silicon wafers.

[7] The compound is often the most abundant airborne, molecular contamination (AMC) in semiconductor cleanrooms,[8] due to its evaporation into ambient air.

NFPA 704 four-colored diamond Health 1: Exposure would cause irritation but only minor residual injury. E.g. turpentine Flammability 2: Must be moderately heated or exposed to relatively high ambient temperature before ignition can occur. Flash point between 38 and 93 °C (100 and 200 °F). E.g. diesel fuel Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazards (white): no code
