Propylene glycol monomethyl ether acetate (PGMEA/PMA), also known as propylene glycol methyl ether acetate, is a colorless hygroscopic liquid with a special odor. It is a non-polluting solvent with multi-functional groups. Its molecular formula is C6H12O3. It is mainly used as a solvent for printing ink, paint, textile dyes, and textile oil. The electronic grade, which is further purified, can be used as the photoresist solvent and cleaning agent in the production of semiconductor and liquid crystal displays. PGMEA/PMA is flammable, and when the temperature is above 42°C, it may form explosive vapor/air mixture.
Used as a photoresist solvent or as a cleaner in semiconductor production, or it can work in conjunction with PGME for RRC (Reducing Resist Consumption) and EBR (Edge Bead Remove) processes in semiconductor production.
Used as a photoresist solvent or as a cleaner for LCD, or works with PGME for the EBR in LCD production.
