Diethylene glycol methyl ether (CAS No. 111-77-3), also known as 2-(2-Methoxyethoxy)ethanol or
methyl carbitol, is a versatile organic solvent with wide-ranging applications in various industries.
Below are its main application fields:
1. Paint and Coatings Industry
Serves as a high-boiling solvent in water-based and solvent-based paints, coatings, and varnishes.
Improves film-forming properties, pigment dispersion, and surface smoothness.
Enhances the miscibility of resins and additives, suitable for architectural, automotive, and industrial
coatings.
2. Adhesives and Sealants
Used in formulations for adhesives (e.g., epoxy, acrylic, and polyurethane adhesives) to adjust viscosity
and curing rates.
Improves the bonding performance of sealants in construction and automotive applications.
3. Textile and Leather Processing
Acts as a dyeing auxiliary to enhance color absorption and uniformity in textile dyeing processes.
Used in leather tanning and finishing to improve softness and flexibility of leather products.
4. Printing Inks
Functions as a solvent in ink formulations for offset, gravure, and flexographic printing.
Helps control drying speed and improve ink adhesion to various substrates (e.g., paper, plastic, metal).
5. Electronics and Semiconductors
Used as a cleaning agent for electronic components and circuit boards due to its high solvency for oils,
fluxes, and residues.
Applies in the production of lithium-ion batteries as a solvent for electrode pastes.
6. Agriculture and Pesticides
Serves as a co-solvent or emulsifier in pesticide formulations to enhance the solubility of active
ingredients.
Used in herbicides, insecticides, and fungicides for better dispersion and efficacy.
7. Plastics and Polymer Industry
Acts as a plasticizer or processing aid in polymer production to improve melt flow and flexibility of
plastics (e.g., PVC, polyesters).
Used in the synthesis of polyurethanes and other high-performance polymers.
8. Pharmaceuticals and Cosmetics
Occasionally used as a solvent or humectant in pharmaceutical formulations (e.g., topical creams, lotions).
Applies in cosmetic products (e.g., perfumes, hair care items) for its mild solvency and low volatility.
9. Industrial Cleaning and Degreasing
Used in industrial cleaning agents to remove grease, oil, and organic contaminants from machinery,
equipment, and metal parts.
Effective in both aqueous and solvent-based cleaning solutions.
10. Chemical Synthesis and Laboratory Applications
Serves as a reaction medium or solvent in organic synthesis due to its good thermal stability and
compatibility with various reagents.
Commonly used in laboratories for research and development of fine chemicals.
Key Properties Enabling Its Applications:
High boiling point (194–195°C), low volatility, and excellent solvency for polar and non-polar substances.
Good miscibility with water and other organic solvents (e.g., alcohols, ketones, esters).
Low toxicity and relatively mild environmental impact compared to some other glycol ethers.
For specific application requirements, it is recommended to consult suppliers or technical data sheets
(TDS) for detailed usage guidelines and safety information.
