Description
Triethylene glycol monomethyl ether (CAS 112-35-6), also known commercially as Methyltriglycol, Methyltrioxitol, and Dowanol TMAT, is a glycol ether solvent with the molecular formula C7H16O4. It carries no assigned E-code and is registered under EC number 203-962-1.
In coatings and printing inks, it functions as a slow-evaporating carrier solvent that extends open time and improves film levelling. In water treatment formulations, it acts as a co-solvent for biocidal actives, enhancing their dispersion and antimicrobial efficacy. It also serves as a reactive crosslinker in adhesive and sealant systems where controlled curing is required.
Triethylene glycol monomethyl ether is supplied as a clear liquid and is subject to REACH registration requirements within the EU. It is classified under HS code 29094990 for customs purposes. Procurement teams should confirm available packaging formats and technical grade specifications directly with the supplier.
