Colourless, volatile solvent with good solvent power for numerous natural and synthetic resins. Solvent in the coatings, printing inks, and chemical downstream industries.
n-Propyl acetate is a clear, volatile, mobile liquid with a characteristic odour reminiscent of acetone. It is miscible with many common solvents, e. g. alcohols, ketones, aldehydes, ethers, glycols and glycol ethers, but it is only sparingly soluble in water.
n-Propyl acetate is primarily intended as a solvent in the coatings and printing inks industries. Its properties are important for the manufacture and processing of numerous products in these branches of industry, e. g. its good solvent power for many resins, its high volatility, and its mild odour. Another factor of great significance in these branches of industry is that the solvent power and thinnability of n-propyl acetate are comparable to those of ethyl acetate. For instance, it dissolves many natural and synthetic resins (e. g. cellulose nitrate, acrylates, alkyd resins, rosin, plasticizers, waxes, oils and fats) and is thus an eminently suitable solvent for wood lacquers and industrial finishes. The main applications for n-propyl acetate in the printing inks industry are flexographic and special screen printing inks.
In the patent literature, n-propyl acetate has been included in a list of volatile acetates as an ecologically benign CFC-free solvent for aerosol sprays.
