Glycol Ether PMA - (Mono) Propylene Glycol (Mono) Methyl Ether Acetate - is a colorless, combustible liquid with low toxicity. It has a characteristic ester odor and is soluble in water to the extent of 18% at 20°C. It has excellent solvency for a variety of substances including acrylic, nitrocellulose and urethane coating resins. Glycol Ether PMA is a substitute for certain ethylene glycol (E-series) ether acetates, particularly EEA and EMA.

Product Data and Technical Information
Corporate Statement
Propylene Glycol Ether acetates (PGEAs) are high-performance industrial solvents for paints and coatings, cleaners, inks, and a variety of other applications. These "P-series" glycol ether acetates have become the solvents of choice for reformulations and new product development. Propylene glycol ether acetates are based on reacting propylene glycol ethers with acetic acid.
Benefits & Applications
Glycol Ether PMA is extensively used in many decorative and protective coating formulations. Glycol Ether PMA has a similar evaporation rate and solvency compared to EEA in an acrylic-epoxy baking enamel formulation. It is also found to give better gloss and image distinction.
Propylne glycol ethers are generally recommended over their acetates because acetates are subject to hydrolysis in very alkaline water-based cleaners. However, for solvent-based cleaning, including metal degreasing and specialized equipment cleansing Glycol Ether PMA alone and in conjunction with other solvents is being evaluated as a replacement for many chlorinated solvents. The direction of current regulations is to eliminate the use of many chlorinated solvents in this application.
Glycol Ether PMA-Electronic has replaced EEA in photoresist formulations used in semiconductor processing. In these processes, it is used in the positive photoresist formulation. Glycol Ether PMA-Electronic may also be used in solvent systems for cleaning and degreasing circuit boards and removing solder flux.
Glycol Ether PMA shows very broad solvency. Its solvency characteristics generally match those of chlorinated solvents more closely than do glycol ethers and alcohols.
