Acetates & Esters, High-Purity Solvents

Diethylene Glycol Monoethyl Ether Acetate (DEGEEA)

Diethylene Glycol Monoethyl Ether Acetate, commonly known as DEGEEA or Carbitol Acetate (CAS: 112-15-2), is a high-performance, slow-evaporating glycol ether ester. Characterized by its clear, colorless appearance and mild, pleasant odor, it serves as an indispensable solvent in specialized industrial applications. The molecular structure of DEGEEA combines ether and ester functionality, providing it with unique solvency characteristics that bridge the gap between water and organic systems. It is particularly valued for its high boiling point and low vapor pressure, which allow for precision control over drying times in coatings and inks. By facilitating superior flow and leveling, DEGEEA ensures the production of high-quality, defect-free finishes. Its compatibility with diverse resin systems, such as cellulose nitrate, acrylic, and epoxy, makes it a versatile tool for formulators. Furthermore, its chemical stability and relatively high flash point contribute to its profile as a reliable and safer solvent choice for high-specification industrial manufacturing processes.
