DOWFROST HD 30% inhibited propylene glycol (PG) is comprised of about 94% PG and 6% corrosion inhibitors, and then diluted 70% by reverse-osmosis water. The lower PG content in DOWROST HD 30% allows for additional corrosion inhibitors including some which are not approved by FDA as GRAS. These additional components do not compromise fluid toxicity and provide an enhanced level of corrosion protection which is unsurpassed in the industry. DOWFROST HD 30% has a fluorescent yellowish green color and is capable of operating at higher temperatures than regular DOWFROST: from 10 °F to 325 °F.
DOWFROST HD 30% is intended for low toxicity, non-food processing applications.
