Product Description

Eastman™ Isobutanol (isobutyl alcohol) is a medium boiling, slow evaporating, colorless liquid that is useful in organic synthesis, as a chemical intermediate and as a solvent in coating applications. Isobutanol is similar in properties to n-butyl alcohol and may be used as a supplement or replacement for it in many applications. As a latent solvent in lacquers and ambient-cured enamels, isobutanol is effective in reducing the viscosities of many formulations while simultaneously promoting flow and leveling. It is also used as an etherification alcohol in the manufacture of amino resins that are used as curing agents in baking and physical-drying finishes.

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