A formulation of propylene glycol and a specially designed package of industrial corrosion inhibitors. The fluid is dyed fluorescent yellow to aid in leak detection.

Not approved by the USDA or FDA for food use, and is not suitable for food or beverage application.




Product Overview

DOWFROST HD inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors. The lower PG content in DOWROST HD allows for additional corrosion inhibitors including some which are not approved by FDA as direct food additives. 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 is capable of operating at higher temperatures than regular DOWFROST: from 0 F to 325 F. DOWFROST HD is intended for low toxicity, non-food processing applications and provides freeze protection down to -60 F. Dowfrost HD is offered is various concentrations and package sizes.
