Glycol Ethers & Acetates

DOWANOLâ„¢ PM glycol ether is the fastest evaporating solvent in the DOWANOLâ„¢ glycol ether family. With very high water solubility and active solvency, DOWANOLâ„¢ PM glycol ether is widely used in coating and cleaning applications. It offers better viscosity reduction than heavier molecular weight glycol ethers and is particularly effective in epoxy and high solids acrylic systems. DOWANOLâ„¢ PM can also be used in combination with DOWANOLâ„¢ PnB glycol ether in glass cleaning formulations.
