Triethylene glycol monoethyl ether

Triethylene glycol monoethyl ether (CAS 112-50-5), sold commercially as Dowanol TE, is a slow-evaporating glycol ether solvent used to control drying rates and improve flow.

Where is Triethylene glycol monoethyl ether used?

• Coatings and printing: extends open time
• Printing inks: retarder solvent preventing premature drying on press
• Gravure and flexographic operations: reduces screen clogging
• Architectural and industrial coatings: improves leveling and reduces brush marks in waterborne and solvent-based systems
• Adhesives: extends working time in contact and pressure-sensitive formulations
• Sealants and elastomers: coalescing aid and plasticizing solvent
• It maintains flexibility and processability in finished products.

Good to know: Its low volatility and strong solvency for resins and pigments make it a preferred carrier where rapid evaporation causes defects.

Commercial specifications

• Clear, low-viscosity liquid in drums, IBCs, and bulk tanker quantities
• High-purity grades for specialty formulation work with tighter quality specifications
