Technical Data Sheet
Product Name DOWANOL™ PMA
Synonyms Propylene glycol methyl ether acetate; 2-Methoxy-1-methylethyl acetate; 1-
Methoxypropylacetate.
Chemical Formula
(major isomer)
Product Description DOWANOL™ PMA glycol ether has the lowest viscosity of the entire line of
DOWANOL™ glycol ethers (1.1 centipoise at 25oC), and it provides superb viscosity
reduction. The remaining OH group in the glycol ether molecule is capped with an
acetate group, which reduces its polarity and reduces the solvent’s viscosity. The
acetate group also eliminates the reactive hydrogen from the OH group found in other
glycol ethers; thus, DOWANOL™ PMA glycol ether is an excellent solvent choice for
urethanes and other proton-sensitive systems. DOWANOL™ PMA glycol ether is a
relatively fast-evaporating glycol ether, and it sets a performance standard in high-
solids, solvent-borne systems. It provides excellent active solvency for a very wide
range of resin types, including acrylics, epoxies, alkyds, polyesters and many other.
Applications • Active solvent for solvent-based coatings.
• Active solvent for solvent-based silk screen printing inks.
• Aprotic solvent in coating systems where OH reactivity is unwanted
(e.g. PU/isocyanate and epoxy).
