Iso-Propyl Acetate (IPAC), identified by CAS number **108-21-4**, is a clear, colorless liquid ester with a characteristic fruity odor. Chemically, it is synthesized through the esterification of acetic acid and isopropanol. Within the acetate ester family, IPAC occupies a critical niche due to its intermediate evaporation rate—falling between the rapid volatility of ethyl acetate and the slower drying profile of n-butyl acetate.
This specific evaporation profile makes it a highly sought-after solvent in the coatings and printing industries, where controlled drying and film formation are paramount. IPAC exhibits excellent solvency power for a broad spectrum of resins, including nitrocellulose, acrylics, vinyls, and polyurethanes. It is miscible with most common organic solvents but has limited solubility in water. Because of its relatively low toxicity and high efficiency in dissolving resins, it is frequently utilized as a high-performance alternative to more hazardous solvents in industrial formulations.
