Product Description

Eastman™ Isobutyl Acetate is a medium boiling solvent with a typical mild, fruity, ester odor. It resembles n-butyl acetate and methyl isobutyl ketone in solvent performance and can be used as a replacement for these solvents in many formulations. Its combination of good solvent activity, desirable evaporation rate, and pleasant odor enables it to be used in a wide range of coating applications.

The chemical substances for this product are listed as Inert Ingredients Permitted for Use in Nonfood Use Pesticide Products under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA). For details on specific permissions, click here.
