Product Description

Eastman™ DIBK (Diisobutyl Ketone) is a slow evaporating, low density solvent that has good activity for many synthetic resins including nitrocellulose, rosin esters, phenolics, hydrocarbons, alkyds, polyesters, and acrylics. It is useful as a retarder solvent to improve flow and minimize humidity blushing. The low density and low surface tension of DIBK enables formulators to develop high-solids coatings with low VOC content and excellent flow and leveling properties.

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.
