1. Product Property
Ethylene glycol ethyl ether is a clear, colorless liquid with a mild, pleasant odor. It is miscible with water and most organic solvents, including alcohols, ketones, and esters. It has a boiling point of approximately 135°C and a flash point of around 42°C, making it a flammable solvent. It exhibits good solvency for resins, lacquers, and dyes, and is known for its low volatility and high dilution ratio. It is hygroscopic and can form peroxides upon prolonged exposure to air.

3. Application Scope and Usage
Ethylene glycol ethyl ether is widely used as a solvent in the formulation of paints, coatings, inks, and cleaning agents. It is particularly effective in dissolving nitrocellulose, acrylic resins, and epoxy compounds. It is also used in the electronics industry for cleaning and degreasing components. In addition, it serves as a coupling agent in water-based systems and as a coalescing agent in latex paints. Its low evaporation rate and excellent solvency make it ideal for use in high-performance coatings and specialty chemical formulations.
4. Package and Storage
Ethylene glycol ethyl ether is typically packed in 200-liter steel drums or IBC tanks (1000 liters). It should be stored in a cool, dry, and well-ventilated area away from direct sunlight, heat sources, and ignition points. Containers must be tightly sealed to prevent moisture absorption and oxidation. Avoid contact with strong oxidizing agents and acids. Proper grounding and bonding are required during transfer to prevent static accumulation. Shelf life is generally 12 months under recommended storage conditions.
