Propilen glikol metil eter asetat, PMA şeklinde kısaltılmıştır. Propilen glikol metil eter asetat, akrilik, nitroselüloz ve poliüretan boya reçinesi gibi maddeler için mükemmel çözücülüğe sahiptir.
Propilen glikol metil eter asetat, selülozik sistemlerde yüzeyi düzenler. Çözücülüğü iyi olup, solvent uçma hızını dengeler. Kaynama noktası yüksek olduğundan kuruma geciktirici olarak da görev yapar. Poliüretan, selülozik sistemlerde yüzeyi düzenlemektedir. Propilen glikol metil eter asetat, solvent uçma hızını dengeler, kaynama noktası yüksek olduğundan kuruma geciktiricidir. 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] and by Shell Chemical under the name methyl proxitol acetate.[4][5]
In the semiconductor industry, PGMEA is a commonly used solvent, primarily for the application of surface adherents such as Bis(trimethylsilyl)amine (HMDS) on silicon wafers.[6] The compound is often the most abundant airborne, molecular contamination (AMC) in semiconductor cleanrooms,[7] due to its evaporation into ambient air. Application
Propylene glycol monomethyl ether acetate has been used in the development of fluidic channels to be incorporated in a poly(dimethylsiloxane) (PDMS)-based microfluidic device.[5]
General description
Propylene glycol monomethyl ether acetate (PGMEA) is a photoresist solvent.[4] Its degradation by microorganisms in different soil types has been investigated.[2] An oral reference dose (RfD) value of PGMEA has been obtained from inhalation studies.[1] The solubility of (5-alkylsulfonyloxyimino-5H-thiophen-2-ylidene)-2-methylphenyl-acetonitriles in PGMEA has been analyzed.[3]
