Description

Ethylene glycol monomethyl ether (CAS 109-86-4) is a glycol ether solvent also known commercially as Dowanol EM, methyl oxitol, and 2-methoxyethanol. It is registered under EC 203-713-7 and carries the molecular formula C3H8O2. No E-code designation applies to this substance.

In coatings and printing inks, it functions as a coalescing solvent that improves film formation by slowing evaporation and enhancing resin compatibility. In polymer processing, it acts as a crosslinking agent and heat stabilizer, helping to control cure rates and protect polymer chains from thermal degradation. It also serves as an antimicrobial carrier in preservation systems.

This product is supplied as an industrial-grade liquid and falls under HS code 29094900. It is subject to REACH regulation and classified as a substance of concern under EU harmonised classification, requiring compliant handling documentation. Procurement teams should confirm SDS and regulatory status prior to ordering.
