Triethylene glycol monoethyl ether
Description
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. It helps extend open time in coating and printing formulations.
Its low volatility and strong solvency for resins and pigments make it a preferred carrier in systems where rapid evaporation causes defects. In printing inks, it functions as a retarder solvent to prevent premature drying on press.
This chemical reduces screen clogging in gravure and flexographic operations. Architectural and industrial coatings use it to improve leveling and reduce brush marks in both waterborne and solvent-based systems for better finishes.
Adhesive formulators incorporate it to extend working time in contact adhesives and pressure-sensitive formulations. This is critical to bond quality where open time must be maintained during the application process.
Sealant and elastomer compounders use it as a coalescing aid and plasticizing solvent. These properties help maintain flexibility and processability in finished products across various industrial and commercial environments.
Triethylene glycol monoethyl ether is supplied as a clear, low-viscosity liquid in drums, IBCs, and bulk tanker quantities. Technical grade is the standard commercial offering for industrial coatings and inks.
High-purity grades are available for specialty formulation work requiring tighter quality specifications. Our logistics network ensures reliable delivery of this essential solvent for your manufacturing and production needs.
