Diethylene glycol ethyl methyl ether

Diethylene glycol ethyl methyl ether (CAS 1002-67-1), also known as diethylene glycol methyl ethyl ether, is a slow-evaporating glycol ether solvent used across coatings, electronics, and printing applications.

Its controlled evaporation profile supports formulation stability and film formation in demanding industrial processes. In coatings and inks, it functions as a coalescing solvent and viscosity modifier.

This chemical improves flow and leveling in both solvent-borne and high-solids systems. Electronics manufacturers use it in photoresist strippers, cleaning formulations, and specialty process fluids.

Controlled solvency and low residue are critical in these high-tech environments. In adhesive and sealant formulations, it aids in adjusting open time and improving substrate wetting across polymer systems.

Printing operations rely on it to balance ink rheology and drying speed. This is particularly important in gravure and flexographic processes where solvent balance directly affects the final print quality.

The product is supplied as a clear liquid in drum and IBC quantities, with bulk tanker options available for larger volumes. Technical grade is the standard commercial offering for industrial use.

Purity specifications typically range from 98% to 99%+, with low water content grades available. These specialized grades are essential for moisture-sensitive formulations and high-precision manufacturing.
