Product Description

Eastman EastaPure™ EP solvent is a high flash point, water miscible, colorless solvent providing slow evaporation rates and good viscosity control for a broad range of polymers, resins and coatings. It is completely water miscible over a wide range of temperatures making it a very good coupling solvent for resin/water systems.

Miscible with most organic solvents, EastaPure™ EP can be blended to provide customized formulation properties necessary for specialty 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.
