Product Description

Eastman™ EP Solvent (Ethylene Glycol Monopropyl Ether) is a colorless, water-miscible solvent providing a slow evaporation rate, good viscosity control in waterborne resins, and high flash point. Eastman™ EP Solvent has a milder, less detectable odor than most other glycol ethers, enhancing its use in coatings when mild odor is desirable. Eastman™ EP Solvent is completely water miscible over a wide range of temperatures. Eastman™ provides this solvent stabilized with BHT (butylated hydroxytoluene).
