Specific gravity: approximately 1.055 at 20 °C
Not regulated for transport by DOT

Frequently Asked Questions About Ethylene Glycol 40/60

What is Ethylene Glycol 40/60?

A nominal 40/60 blend of ethylene glycol (CAS 107-21-1) and deionized water, prepared by volume: 40 volumes ethylene glycol to 60 volumes deionized water, which is 42.6 % by weight. It is uninhibited — it contains no corrosion-inhibitor package and no dye.

What freeze protection does Ethylene Glycol 40/60 provide?

Approximately -24 °C (-12 °F) freezing / crystallization onset, with a specific gravity of about 1.055 at 20 °C. These are typical reference values for the blend, not lot measurements.

How is this different from Inhibited Ethylene Glycol 40/60 with OAT-908?

Same 40/60 glycol-to-water ratio, but this product is uninhibited and undyed. The OAT-908 product carries an organic-acid corrosion-inhibitor package for data-center and closed-loop cooling. Choose the inhibited product where metal corrosion protection is required.

Do you provide an SDS and COA for Ethylene Glycol 40/60?

Yes. The Safety Data Sheet (SDS) and a lot-specific Certificate of Analysis (COA) are available on request at no charge. Contact sales@alliancechemical.com or call (512) 365-6838.

What is Ethylene Glycol 40/60 and what is its chemical formula?

Ethylene Glycol 40/60 is listed under CAS 107-21-1 (PubChem reference search). The catalog formula is C2H6O2. The listed molecular weight is 62.07 g/mol. For solutions and blends, identity values may describe a constituent; consult the product SDS for composition.

What are the physical properties of Ethylene Glycol 40/60?

Catalog reference information for Ethylene Glycol 40/60: form: Liquid; melting point: -24 °C (freeze / crystallization onset); boiling point: ~104 °C; flash point: Not flammable (aqueous solution); reference values may describe a pure substance rather than the supplied concentration or blend. Confirm applicable conditions and specifications in the product documents; these values are not batch test results.

What grade and purity of Ethylene Glycol 40/60 does Alliance Chemical offer?

Alliance Chemical lists Ethylene Glycol 40/60 in Technical Grade. Check the product specification for the measurement basis and acceptance limits. A grade label alone does not establish certification or suitability for a regulated application. For batch results, request a COA using the product name and lot number.

What are common industrial applications of Ethylene Glycol 40/60?
