Diethylene glycol (DEG)

Diethylene glycol (DEG) (111-46-6) DEICER

This DEICER is a clear, colorless liquid, identified by its mild characteristic odor, and is composed entirely of Diethylene glycol (DEG). Its primary application is as a deicing and anti-icing fluid for aircraft ground operations. Key characteristics include a boiling point of 245°C (473°F), a freezing point of -10°C (14°F), and complete solubility in water. With a specific gravity of 1.118 and a flash point of 138°C (PMCC), it exhibits stability under normal conditions. It is mildly corrosive to certain metals and requires storage in a cool, dry, well-ventilated area.
