Product Application of Propyl Acetate CAS#109-60-4
Propyl acetate is widely employed as an outstanding solvent for coatings, printing inks, nitrocellulose lacquers, varnishes, and numerous resin systems. It also finds broad application in the flavor and fragrance sector.
As a mild, quick-evaporating solvent, it is frequently used in flexographic and gravure printing inks, especially for printing onto olefin and polyamide films. Additionally, it acts as a solvent for nitrocellulose, chlorinated rubber, and thermosetting phenolic resins.
This compound possesses a gentle fruity scent that evolves into a pear-like aroma upon dilution. It is naturally present in bananas, tomatoes, raspberries, and various other fruits. Under China's GB2760-86 standard, it is permitted as an edible flavoring agent and is primarily utilized in formulating pear, gooseberry, and other fruit-type flavors.
Propyl acetate also demonstrates excellent dissolving power for a wide array of synthetic resins, including ethyl cellulose, nitrocellulose, styrene, and methacrylate resins. It is extensively used as a solvent in organic synthesis, coatings, and printing inks, and additionally functions as an effective industrial dehydrating agent.
