Fax: 720.554.0909, General Information American Galvanizers Association Any standard automotive-grade glycol (aka antifreeze) (ethylene or propylene) should be fine, having much the same inhibitors as metalguy suggests. Propylene glycol is also used for its heat transfer and freeze protection properties. Because propylene glycol fluids have low acute oral toxicity, DOWFROST is often used in applications where contact with food or beverage products could occur. V    It buffers the organic acids formed as a result of glycol oxidation. L    Propylene Glycol is highly soluble in water, and readily metabolized by microbes and higher organisms once released into the environment. | E    Propylene glycol (also known as 1, 2-propanediol) is a chemical compound with the molecular formula C3H8O2. It treats the surfaces of the metal making them less susceptible to corrosion. J    This is why corrosion inhibitors are added to glycols used as heat transfer fluids. R    Propylene Glycol is a propanediol that exists as a clear, colorless and hygroscopic liquid and consists of propane where the hydrogens at positions 1 and 2 are substituted by hydroxyl groups. The biodegradation process requires oxygen; therefore, dissolved oxygen (DO) concentrations in receiving waters may be negatively impacted following a large Propylene Glycol release. Its chemical formula is CH3CH(OH)CH2OH. 2 gallons is enough chemical to use to convert one 55 gallon container from just propylene glycol to corrosion inhibited propylene glycol. G    Please note that temperature or concentration information are not given for this corrosion rate. Industrially inhibited propylene glycol fluid with an operating range of -60F to 350F. Straight propylene glycol is used in systems that do not require corrosion protection. PEAK Automotive Coolants are formulated to meet or exceed the performance requirements of every major car and truck manufacturer in order to provide maximum protection. N    aga@galvanizeit.org, Site Map • A    INTERCOOL® P-300 is designed for heavy duty demanding applications that require a higher level of corrosion inhibitors and pH buffers. It is design for antifreeze or boiler applications and will provide freeze protection and corrosion protect against iron, aluminum, and … You would only want to add Sludgehammer if your pH is below 9.5 for non-aluminum system. An industrially inhibited glycol is essential in HVAC systems with steel piping to prevent fouling, clogging, and the buildup of precipitate… Propylene glycol and ethylene glycol are widely used in the HVAC industry to protect systems from damage caused by freezing and corrosion. In general, glycols are non-irritating and have very low volatility. Ethylene Glycol (EG) has very important characteristics that tailor the coolant mix to the automotive application. It is important to use additional chemical inhibitors in conjunction to propylene glycol when it is applied to metallic surfaces. The incorporated propylene glycol inhibitor serves to modify metallic surfaces by absorption. Terms of Use - Ethylene glycol-based glycol-based fluids. Sierra Propylene Glycol Antifreeze.

Then again, this is a closed-loop cooling circuit, correct? Propylene glycol-based antifreeze solutions typically have a much higher electrical conductivity than glycerin-based antifreeze solutions, with a range of about 1800-2500μS/cm. In general, the main issue with glycols is the formation of acids by glycol degradation at elevated temperatures. Propylene glycol heat transfer fluid contains a performance additive that prevents metal corrosion, lowers maintenance costs and improves heat transfer. Place your order through our on-line store, to reduce your cost and waiting period. Industrial Inhibitors Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste. Search. It provides optimum corrosion protection for most metals, including copper, steel, brass, etc., and it does in two ways. As a result, using propylene glycol-based antifreeze in a fire protection system could increase the rate of corrosion versus using a glycerin-based antifreeze. - Renew or change your cookie consent, An Intro to Pipeline Corrosion and Protection Methods, Innovative Coating Solutions for Oil Sands Equipment, 7 Methods of Coating Thickness Measurement.

Hot-dip vs Cold Galvanizing: What’s the Difference? It is an organic solvent clear in color, and corrosive to most metallic surfaces. The goal should be to minimize the amount of glycol in the fluid mixture, while maintaining the needed freeze protection and corrosion inhibitor content. Because propylene glycol has a low toxicity level, it can be used in equipment that has contact with food products and beverages. M    #    U    For systems, with metal you may select a corrosion inhibited glycol system or purchase a propylene glycol product and use a corrosion inhibitor overlay. How Corrosive is Propylene Glycol to Hot-Dip Galvanized Steel? The primary difference between propylene glycol and ethylene glycol is toxicity and heat transfer characteristics.
