Product Description

Eastman EastaPure™ EB solvent is a high flash point, water miscible, colorless solvent providing slow evaporation rate and good viscosity control for a broad range of polymers, resins and coatings. It is primarily used in the production of electronic components in the etching and photoresist processes.

Miscible with most organic solvents and water, EastaPure™ EB solvent enables formulators to develop customized blends that meet the most demanding requirements for electronic chemicals in wet processing and photoresist applications.

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.
