Triethylene glycol monobutyl ether

Triethylene Glycol Monobutyl Ether (CAS 143-22-6) is a glycol ether solvent also known commercially as Dowanol TBAT, Butyltriglycol, and Butoxytriglycol. It carries no assigned E-code and is classified under HS code 29094990. The compound is recognised across supplier documentation under the abbreviations BTG and TGBE.

In waterborne coatings, it functions as a coalescing solvent, reducing the minimum film-forming temperature and improving surface levelling. In printing inks and adhesive formulations, it acts as a coupling agent that stabilises pigment dispersions and controls viscosity. It also serves as a reactive diluent in crosslinking systems, where its hydroxyl groups participate directly in curing reactions.

The material is supplied in industrial grades compliant with REACH registration requirements. Standard packaging includes drums and IBC containers, with bulk availability depending on supplier. Buyers should confirm SDS documentation and purity specifications prior to procurement to ensure suitability for their specific formulation requirements.
