Description

Triethylene glycol monomethyl ether (CAS 112-35-6 ), also known as methoxytriethylene glycol, is a slow-evaporating glycol ether solvent used across coatings, printing, and industrial cleaning applications. Its low volatility and water miscibility make it a practical carrier and coupling agent where controlled drying and solubility balance are procurement priorities for chemical manufacturers. In waterborne coatings and adhesives, it functions as a coalescing solvent and viscosity modifier, improving film formation and open time in architectural and industrial formulations. Inkjet and offset printing inks use it as a high-boiling solvent to control drying speed and prevent nozzle clogging on press, ensuring consistent performance during long production runs. In water treatment formulations, it acts as a carrier for biocidal actives, aiding dispersion and improving contact efficacy in treatment programs across various industrial cooling systems. Sealant and elastomer manufacturers incorporate it as a reactive diluent or processing aid where controlled curing and compatibility with polar substrates are required for high-performance bonds. This chemical is supplied as a clear, low-viscosity liquid in drum and IBC quantities. Technical grade is the standard commercial offering for most industrial and cleaning applications. High-purity grades are available for specialty coatings and electronics applications. Bulk supply is available for large-volume industrial buyers requiring consistent logistics and delivery.
