Yellow dyed, Industrial-Grade Inhibited Propylene Glycol (PG) Thermal Fluid for Heat Transfer Applications between -45°C and 160°C (-50°F and 325°F).
Product Overview

DOWFROST™ HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. DOWFROST™ HD (heavy duty) has a lower PG composition to allow for higher concentration of corrosion inhibitors for maximum protection & rust prevention. These additional components do not compromise toxicity fluid and provide an enhanced level of corrosion protection which is unsurpassed in the industry.

DOWFROST™ HD has a fluorescent yellow color and can operate at higher temperatures than regular DOWFROST™. DOWFROST™ HD is suitable for use in environments between -50°F and 325°F (-45°C and 160°C).

DOWFROST™ HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F.

DOWFROST™ HD is available in a range of prediluted concentrations and package sizes.
