DOWANOL PMA Propylene glycol methyl ether acetate 108-65-6 Dow Chemical Solvent >> Glycols & glycol ether >> Propylene Glycol Acrylic/Acrylate Resins Alkyd Resins Epoxy Resins Polyester Coatings >> Solventborne Inks >> Solvent-based INKS >> Screen inks Slightly soluble in water DOWANOL* PMA glycol ether has the lowest viscosity of the entire line of DOWANOL glycol ethers (1.1 centipoise at 25°C), 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 others. It possesses powerful solvency, high dilution ratio, moderate evaporation rate, viscosity control. It is used as an active solvent for solvent-based coatings and solvent-based silk screen printing inks, aprotic solvent in coating systems mwhere OH reactivity is unwanted (e.g. PU/isocyanate and epoxy). Propylene glycol methyl ether acetate. Used in silk screen printing inks and coatings. Possesses powerful solvency. Offers high dilution ratio and moderate evaporation rate.
