Description

  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[2] and by Shell Chemical under the name methyl proxitol acetate.

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


Application: 

  •   High-grade solvent: its molecules are in both ether bonds and carbonyl groups, and the carbonyl groups are formed the structure of ester, while they contain alkyl groups. In the same molecule, there are both non-polar parts and polar parts. The functional groups of these two parts are mutually restricted and excluded, and each has its own inherent function. Therefore, it has a certain dissolving ability to the non-polar substances and polar substances.

  • Industrial solvent: having a strong dissolving ability to the non-polar substances and polar substances, so it applies to be used as the solvent for high-grade coating, ink and all kinds of polymers.

  • Non-pollution solvent: it is a kind of auxiliary solvent, which is indispensable to improve the strength of coating in the coating industry. It is widely used as the high-grade paint such as, car paint, TV paint, refrigerator paint, aircraft paint and others.

  • Used as the solvent of ink, paint, ink, textile dyes, and textile oil.

  • Used as the cleaning agent in production of liquid crystal display devices.
