Triethylene glycol monobutyl ether

Triethylene glycol monobutyl ether (CAS 143-22-6), commonly abbreviated as TEGBE, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and adhesive formulations. Its controlled evaporation rate and compatibility with both water-based and solvent-based systems make it a practical choice for formulators managing film formation and flow behavior.

In architectural and industrial coatings, TEGBE functions as a coalescing agent and flow promoter, improving film leveling and reducing surface defects in waterborne systems. Printing ink manufacturers incorporate it to extend open time and maintain viscosity stability across UV-curable and solvent-based ink formulations for various industrial applications.

In adhesive and sealant production, it supports cross-linking processes and acts as a reactive diluent to adjust application viscosity without compromising cure performance. Industrial and institutional cleaning formulations use TEGBE as a degreasing co-solvent, where its slow evaporation improves contact time on hard surfaces for better results.

Triethylene glycol monobutyl ether is supplied as a clear liquid in standard packaging including drums and IBC totes, with bulk quantities available for industrial buyers. It is offered primarily in technical grade, with high-purity specifications available for demanding coating and ink applications requiring strict quality control measures.
