Description

Dipropylene Glycol Dimethyl Ether is a high-purity, aprotic solvent known for its excellent solvency power and high boiling point. This versatile chemical is valued for its ability to dissolve a wide range of polar and non-polar substances, making it a critical component in advanced formulations. It is primarily sought after by manufacturers in the coatings, electronics, and specialty chemical industries for applications requiring stable, low-volatility performance.

Application

• Industrial Coatings & Inks: Acts as a high-boiling, slow-evaporating solvent in urethane, epoxy, and acrylic formulations, improving flow and leveling.
• Electronics Manufacturing: Used as a solvent and carrier in photoresist strippers, PCB cleaners, and flux removal agents due to its stability and purity.
• Chemical Synthesis & Reaction Medium: Serves as an inert, high-temperature solvent for organometallic reactions, Grignard reactions, and polymerization processes.
• Specialty Cleaning & Degreasing: Employed in precision cleaning formulations for metal parts and optical components where low residue is essential.
• Agricultural & Pharmaceutical Intermediates: Functions as a solvent in the synthesis of active ingredients and other fine chemicals.
• Gas Treating & Absorption: Utilized as a physical solvent in gas sweetening processes to remove acid gases like CO₂ and H₂S.

Quality Control

Our Dipropylene Glycol Dimethyl Ether is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including GC and Karl Fischer titration, to ensure it meets precise specifications for purity, water content, and other critical parameters. Certificates of Analysis (COA) are provided with each shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture and degradation of quality.
