Main Applications
Coatings
DEGME can be used as a solvent component in selected coating formulations to support the required solvency and processing characteristics.
Application suitability should be evaluated according to the resin system, pigments, solvent blend, and application conditions.
Inks
Diethylene Glycol Monomethyl Ether may be used as a solvent component in selected ink formulations. Selection should take into account the ink resin, printing process, drying conditions, and other formulation ingredients.
Industrial Cleaning
DEGME can be incorporated into certain industrial cleaning formulations. Its suitability should be assessed based on the substrate, type of contamination, contact time, and cleaning process.
Chemical Formulations
Due to its glycol ether structure, DEM can also serve as a solvent or co-solvent in selected industrial chemical formulations. The appropriate use depends on formulation requirements and the intended end product.
