Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol Acetate

Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol 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.

Chemical Name: 1-Methoxy-2-Propanol Acetate
Chemical Family: Propylene Glycol Ether Acetate
Other Names:
  • Arcosolv PMA
  • Dowanol PMA
  • Methoxy Propyl Acetate
  • Propylene Glycol Mono Methyl Ether Acetate
  • Methoxypropylacetate
Chemical Formula: C6H12O3

 

Used in: Advantages:
  • Solvent-based coatings
  • Solvent-based silk screen printing inks
  • Coating systems where OH reactivity is unwanted (e.g. PU/isocyanate and epoxy)
  • Powerful solvency
  • High dilution ratio
  • Relatively fast evaporation rate
  • Lowest viscosity; superb viscosity reduction

Benefits and Applications

Coatings

Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol Acetate is extensively used in many decorative and protective coating formulations. Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol 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 Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol 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.Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol 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 Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol Acetate has replaced EEA is in photoresist formulations used in semiconductor processing. In these processes, it is used in the positive photoresist formulation.Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol 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 Methoxy Propanol Acetate / Propylene Glycol Methyl Ether Acetate / 1-Methoxy-2-Propanol Acetate in agricultural, cosmetic, ink, textile and adhesive products.
