Description and Uses

Isobutyl isobutyrate has an odor and taste reminiscent of pineapple. It is used as a flavoring agent, insect repellent, and a substitute for methyl amyl acetate in nitrocellulose lacquers and thinners.

Isobutyl isobutyrate is used principally as a solvent, especially for nitrocellulose lacquers and thinners as well as coatings for plastic substrates, and high-solids coatings. The majority of end uses are in coatings (automotive, industrial, wood furniture, and graphic arts).
