Product Description
Dipropylene Glycol Dimethyl Ether (DPGDME) – High-Performance Solvent for Industrial & Electronic Applications
Dipropylene Glycol Dimethyl Ether (DPGDME, CAS 111109-77-4) is a high-boiling, low-volatility glycol ether solvent widely used in industrial cleaning, coatings, inks, electronics, and chemical synthesis. It is a clear, colorless liquid with a mild ether-like odor, offering excellent solvency power, slow evaporation rate, and favorable environmental properties.
As a low vapor pressure volatile organic compound (LVP-VOC), DPGDME is particularly valued for applications where regulatory compliance, operator safety, and environmental sustainability are priorities. Its versatility, coupled with superior solvency characteristics, has made it an essential raw material in many advanced industries.
Main Applications
Main Applications of Dipropylene Glycol Dimethyl Ether
1. Electronics & Semiconductor Industry
Dipropylene Glycol Dimethyl Ether is widely used in semiconductor cleaning processes, photoresist removal, and LCD panel manufacturing.
- Photoresist stripping: DPGDME dissolves organic coatings effectively without damaging sensitive circuit patterns.
- Wafer cleaning: Removes flux, particles, and organic residues during microelectronics production.
- LCD and OLED panel manufacturing: Acts as a precision cleaning solvent for optical substrates and display components.
- Key Value: Its slow evaporation rate and low residue make it ideal for high-precision electronic applications where surface cleanliness is critical.
2. Coatings, Paints & Printing Inks
DPGDME functions as a high-boiling, low-volatility solvent (LVP-VOC) in a variety of coating and ink formulations.
- Improves flow and leveling in coatings, reducing brush marks and ensuring smooth film formation.
- Enhances pigment dispersion and color development, leading to vibrant and uniform finishes.
- Extends open time and drying time, beneficial for applications requiring longer processing windows.
- Commonly used in industrial paints, printing inks, and specialty coatings where controlled evaporation is required.
- Key Value: Replaces higher-VOC solvents, supporting environmental compliance without sacrificing performance.
3. Industrial Cleaning & Degreasing
DPGDME is an efficient solvent for removing oils, greases, and polymeric residues in industrial cleaning formulations.
- Used in metal degreasing, removing machining oils and contaminants from precision components.
- Applied in optical lens and glass cleaning, providing residue-free results.
- Added into multi-purpose industrial cleaners to boost solvency and reduce drying marks.
- Key Value: Offers strong solvency while being safer and less volatile compared to traditional cleaning solvents.
4. Paint Stripping & Surface Preparation
DPGDME is a common ingredient in paint removers and surface preparation chemicals.
- Penetrates deeply into coatings and softens them for easy removal.
- Works synergistically with other glycol ethers and co-solvents to increase stripping efficiency.
- Suitable for industrial paint removal, wood refinishing, and automotive maintenance.
- Key Value: Provides controlled action with reduced odor and safer handling, compared to conventional harsh stripping agents.
5. Chemical Intermediate & Reaction Solvent
In the chemical industry, DPGDME is employed as a reaction medium and co-solvent:
- Used in polymerization, resin synthesis, and adhesive production.
- Serves as a carrier solvent in specialty chemicals and agrochemical formulations.
- Functions as a stabilizer and solubilizer in complex chemical blends.
- Key Value: Ensures consistent performance in formulations that require high boiling point and strong solvency.
