Glycol Ether PM Acetate is a fast evaporating solvent that has the lowest viscosity of our p-series solvents product line. The molecule is capped with an acetate group, which reduces its polarity and viscosity, as well as eliminates the presence of the reactive hydrogen found in other glycol ethers. These features make it an excellent solvent choice for urethanes and other proton-sensitive systems.

Benefits and Applications
Coatings: Glycol Ether PM Acetate is extensively used in many decorative and protective coating formulations. Glycol Ether PM Acetate 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.
Cleaners: 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 PM Acetate 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 PM Acetate 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 PM Acetate has replaced Ethyl Cellosolve Acetate is in photoresist formulations used in semiconductor processing. In these processes, it is used in the positive photoresist formulation. Glycol Ether PM Acetate may also be used in solvent systems for cleaning and degreasing circuit boards and removing solder flux.
Other Applications: The properties listed in the previous section also support the use of Glycol Ether PM Acetate in agricultural, cosmetic, ink, textile and adhesive products.
