Tetraethylene Glycol (TTEG)
Tetraethylene glycol, more typically referred to as TTEG, is most typically used to make polyester and UV curable resins. It is also frequently used as a chemical intermediate and as a solvent in the manufacture of inks and dyes. Tetraethylene glycol can also be found as a solvent in certain hydrocarbon purification processes and as a heat transfer fluid.
Tetraethylene glycol is produced as a by-product to the production of lower molecular weight glycols.
Pure tetraethylene glycol is a colorless and virtually odorless liquid at room temperature.
