Diethylene Glycol
Description
Diethylene Glycol (DEG-2, 2-Dihyroxydi Ethyl Ether) is a colorless, virtually odorless, viscous liquid. Compared to MEG, it has a higher boiling point, viscosity and specific gravity. DEG is characterized by great solvent power, extreme hygroscopicity, and low vapor loss.
Applications
The viscous glycol ether is an important industrial solvent. It is utilized in the manufacture of unsaturated polyesters, plasticizer, and some important resins. It is a dyeing agent of gases. DEG is an effective softening agent, making glues and adhesives more flexible. It is an important component in formulations of brake fluids pastes and pigments.
