Description
Triethylene glycol monoethyl ether (CAS 112-50-5), also known commercially as Ethyltriglycol, Dowanol TE, and Poly-solve TE, is a slow-evaporating glycol ether solvent with the molecular formula C8H18O4. It carries no assigned E-code and is registered under EC number 203-978-9.
In coatings and printing inks, it functions as a coalescing agent and viscosity modifier, slowing film formation to improve flow and levelling on substrate surfaces. In adhesive and sealant formulations, its high boiling point and water miscibility allow it to dissolve both polar and moderately non-polar resin systems while extending open time during application.
Triethylene glycol monoethyl ether is supplied as a standard industrial-grade liquid and falls under REACH registration requirements for supply within the EU. It is classified under HS code 29094990 for customs purposes. Packaging formats typically include drums and intermediate bulk containers, with documentation available on request.
