Propylene glycol methyl ether acetate
Propylene glycol methyl ether acetate is a P-type glycol ether used in inks, coatings, and cleaners. It is sold by Dow Chemical under the name Dowanol PMA, by Shell Chemical under the name methyl proxitol acetate, and by Eastman under the name PM Acetate.
In the semiconductor industry, PGMEA is a commonly used solvent, primarily for the application of surface adherents such as Bisamine on silicon wafers. The compound is often the most abundant airborne, molecular contamination in semiconductor cleanrooms, due to its evaporation into ambient air.
