Propylene glycol methyl ether acetate (PGMEA, 1-methoxy-2-propanol acetate) is a P-type glycol ether used in inks, coatings, and cleaners. It is sold by Dow Chemical under the name Dowanol PMA, [3] by Shell Chemical under the name methyl proxitol acetate, [4] [5] and by Eastman under the name PM Acetate.

This page contains tables of azeotrope data for various binary and ternary mixtures of solvents. The data include the composition of a mixture by weight (in binary azeotropes, when only one fraction is given, it is the fraction of the second component), the boiling point (b.p.) of a component, the boiling point of a mixture, and the specific gravity of the mixture.
Propylene glycol methyl ether (PGME or 1-methoxy-2-propanol) is an organic solvent with a wide variety of industrial and commercial uses. [3] Similar to other glycol ethers , it is used as a carrier/solvent in printing/writing inks and paints /coatings.
Estimates on the prevalence of propylene glycol allergy range from 0.8% (10% propylene glycol in aqueous solution) to 3.5% (30% propylene glycol in aqueous solution). [ 70 ] [ 71 ] [ 72 ] The North American Contact Dermatitis Group (NACDG) data from 1996 to 2006 showed that the most common site for propylene glycol contact dermatitis was the ...
There is a difference in the mixing ratio, depending on whether it is ethylene glycol or propylene glycol. For ethylene glycol, the mixing ratios are typically 30/70 and 35/65, whereas the propylene glycol mixing ratios are typically 35/65 and 40/60. It is important that the mixture be frost-proof at the lowest operating temperature. [24]
2-Methoxyethanol, or methyl cellosolve, is an organic compound with formula C 3 H 8 O 2 that is used mainly as a solvent.It is a clear, colorless liquid with an ether-like odor.
The soft-bake allows that high residual solvent content minimizes intrinsic stress and improves cross-linking. The SU-8 layer is patterned using soft contact exposure followed by post-exposure bake. The non-exposed SU-8 is removed by immersing in, e.g. propylene glycol methyl ether acetate (PGMEA). [13]
