Glycol Ethers, High-Purity Solvents

Diethylene Glycol Monobutyl Ether Acetate (DBGA)

Diethylene Glycol Monobutyl Ether, commonly known as Glycol Ether DB, is a versatile, clear, and colorless liquid with a faint, characteristic odor. This chemical compound, identified by the CAS number 112-34-5, belongs to the glycol ether family and serves as a powerful high-boiling solvent. Its unique molecular structure allows it to bridge the gap between aqueous and organic systems, providing excellent solvency for a wide range of resins, oils, and waxes. Due to its slow evaporation rate and high boiling point, Glycol Ether DB is indispensable in formulations requiring prolonged open time or enhanced leveling properties. It is highly valued across various industries for its stability and compatibility with other solvents and water. Furthermore, its relatively low toxicity and high flash point contribute to its profile as a safer alternative in industrial processes. As a multi-functional chemical intermediate, it plays a critical role in producing high-quality coatings, cleaners, and specialty fluids.
