Summary (All Ethylene Glycol Properties Listed on Product Pages, See Below)

DOWTHERM SR-1™ ethylene glycol heat transfer fluid includes a specially designed package of industrial corrosion inhibitors. Dow ethylene glycol antifreeze solutions have an operating temperature range of -60°F to 250°F (-51°C to  121°C), and the glycol fluid is dyed fluorescent pink to aid in leak detection.

Ethylene glycol-based fluids are less viscous than propylene glycols. Therefore, they generally provide superior heat transfer efficiency and better low temperature performance. However, in applications where toxicity is a concern, propylene glycols such as DOWFROST HD and Food Grade DOWFROST should be used.
