PMA Propylene Glycol Methyl Ether

PMA Propylene Glycol Methyl Ether Acetate is a colorless, 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

Coatings: 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 acrylicepoxy
baking enamel formulation. It is also found to give better gloss and image distinction.

Cleaners: Glycol Ether propylene 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 shows very broad solvency. Its solvency characteristics generally match
those of chlorinated solvents more closely than do glycol ethers and alcohols.

Electronics: Another area where Glycol Ether PMA has replaced EEA is in photoresist
formulations used in semiconductor processing. In these processes, it is used in the positive
photoresist formulation.
