What is Triethylene glycol monobutyl ether?
Triethylene glycol monobutyl ether (CAS 143-22-6), commonly abbreviated as TEGBE, is a slow-evaporating glycol ether solvent.
Where is Triethylene glycol monobutyl ether used?
- Coatings: coalescing agent and flow promoter, improving film leveling and reducing surface defects in waterborne systems
- Printing inks: extends open time and maintains viscosity stability in UV-curable and solvent-based formulations
- Adhesives and sealants: supports cross-linking and acts as a reactive diluent to adjust application viscosity
- In industrial and institutional cleaning, TEGBE serves as a degreasing co-solvent whose slow evaporation improves contact time on hard surfaces.
Commercial specifications
- Standard packaging: drums and IBC totes; bulk quantities available
- Technical grade; high-purity specifications available
