Glycol ethers are a group of substances in organic chemistry that can be traced back to ethylene glycol or diethylene glycol as the basic units. Glycol ethers are mainly used as solvents, especially in paints, and as a basis for epoxy resins. As solvents, glycol ethers typically have the advantageous solvent properties of lower molecular weight ethers and alcohols, but higher boiling points, which is advantageous for processing.
