Overview
Dipropylene glycol methyl ether (CAS 34590-94-8 ), commonly sourced under the abbreviation DPGME or the trade name Dowanol 50B, is a slow-evaporating glycol ether solvent used across coatings, cleaning, and electronics manufacturing.
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 in various industrial applications.
In architectural and industrial coatings, DPGME functions as a coalescing agent and flow promoter, improving film formation in waterborne latex systems. Electronics manufacturers use it in flux formulations and PCB cleaning processes.
The solvent is particularly valued in electronics where residue-free evaporation is critical. In printing inks and packaging coatings, it supports pigment dispersion and controls drying speed across flexographic and gravure applications.
Adhesive and sealant producers incorporate it as a carrier solvent to adjust viscosity and open time in both water-based and reactive formulations. This versatility makes it a staple in chemical manufacturing.
DPGME is supplied as a clear liquid in drum, IBC, and bulk quantities. Standard commercial grades include technical and industrial purity levels, with high-purity grades available for electronics and specialty cleaning applications.
Specifications typically align with established industry standards for glycol ether solvents, including purity, water content, and color limits. This ensures consistent performance across diverse manufacturing sectors.
