Product Application of Propyl acetate CAS#109-60-4
Propyl acetate is a highly versatile solvent widely utilized in coatings, printing inks, nitrocellulose lacquers, varnishes, and various resin formulations. Beyond its industrial applications, it is also extensively used in the flavor and fragrance industry.
As a mild and fast-evaporating solvent, it is a preferred choice for flexographic and gravure printing inks, especially for printing on olefin and polyamide films. Additionally, it acts as an effective solvent for nitrocellulose, chlorinated rubber, and thermosetting phenolic resins.
Characterized by a gentle fruity scent that develops into a distinct pear-like aroma upon dilution, propyl acetate occurs naturally in bananas, tomatoes, raspberries, and other fruits. It is approved under the GB2760-86 standard as an edible flavoring agent in China, where it is primarily used to formulate pear, gooseberry, and other fruit flavors.
Furthermore, this compound demonstrates outstanding solvency for a broad spectrum of synthetic resins, including ethyl cellulose, nitrocellulose, styrene, and methacrylate resins. It serves as a key solvent in organic synthesis, coatings, and printing inks, while also functioning as an efficient industrial dehydrating agent.
