They are:  . 25% Monopropylene Glycol will reduce the freezing point of water down to -11 to -12°C. Polypropylene glycol (PPG) was investigated as a corrosion inhibitor for typical × 60 pipeline steel in 15% HCl solution using weight loss, electrochemical impedance spectroscopy (EIS), electrochemical frequency modulation (EFM), linear polarization resistance (LPR) and potentiodynamic polarization (PDP) techniques. Propylene Glycol Coolant is a transparent orange liquid. ). ComStar's ProFrost (Propylene Glycol) and Frost Free (Ethylene Glycol) are premium industrial coolants that can be ordered with/or without a color and with/or without a corrosion inhibitor package designed to prevent system corrosion and clog-up’s. ComStar International Inc. manufactures the most comprehensive product line of environmentally safe, industrial strength chemical products for the trade professional in the world. Dynalene Propylene Glycol mixtures use either high-quality technical grade propylene glycol or food grade propylene glycol with or without corrosion inhibitors and additives to fit your process. – Order Online. CORROBAN 99 is a propylene -glycol based antifreeze corrosion inhibitor and biostat specially formulated for use in chilled water and closed heating and cooling systems. Glycol based systems, using Propylene Glycol or Ethylene Glycol, without any corrosion inhibitors or additives, are more corrosive and aggressive than water alone. We supply Food Grade propylene glycol with or without a corrosion inhibitor package. Welcome to Vedra Industries, your on-line source for ethylene glycol,propylene glycol and corrosion inhibitors for HVAC applications Corrosion Inhibitor for PG based systems is a specially formulated multi-metal corrosion inhibitor, preventing corrosion in multiple ways. Addition of corrosion inhibitor prevents copper and cu-alloys corrosion, corrosion on aluminum, steel and cast iron. It is a broad spectrum corrosion inhibitor that improves metal surface by absorption and making it less vulnerable to corrosion. JavaScript seems to be disabled in your browser. Your On-Line Source for propylene glycol, ethylene glycol, corrosion inhibitors and buffer solutions. Potentiodynamic polarization tests were carried out to study the effect of each chemical. Description: mono ethylene glycol and in less toxic propylene glycol coolants. The Glycol, Inc.™ Advantage the best protection and temperature stability for your equipment ChillerGlycol™ DF1 and BoilerGlycol™ DF1 are high purity inhibited propylene glycol heat transfer fluids. Splashes on the skin should be washed off with water immediately. In ComStar also has additional heat transfer product lines for geothermal, sprinkler, boiler and solar systems. It is well compatible with seals, o-rings, rubber hoses and other radiator engine components, improved closed loop system longevity and performance. In most cases you should mix glycol with water. Due to immense corrosion in system, the rust in the system metal makes the glycol turn red in colour, ergo increasing the glycol degradation rate. This protect may be ordered in clear or in pink form. In case of splashing into the eyes, flush them with fresh water and obtain medical attention. It is compatible and fully functional in glycol-water & glycol-ethanol (rectified spirit) mixtures and improves heat transferability. 1 gallon converts 28 gallons of pure 99.9% Propylene Glycol into a 95% solution of Inhibited Propylene Glycol. Glycol Antifreeze Inhibitor WM8703 provides protection for both ferrous and yellow metals and unlike traditional Molybdate and Nitrite inhibitors does not contribute to … The goal should be to minimize the amount of glycol in the fluid mixture, while maintaining the needed freeze protection and corrosion inhibitor content. adroll_adv_id = "6CG5ESNMDRGXXK3RMRYDDL"; Reactions with dissolved oxygen can lead to the formation of organic acids that attack unprotected metal surfaces. Only registered users can write reviews. 2 gallons is enough chemical to use to convert one 55 gallon container from just propylene glycol to corrosion inhibited propylene glycol. 55 gallons converts 1,540 gallons of pure 99.9% Propylene Glycol into a 95% solution of Inhibited Propylene Glycol. Store in a cool dry place. It buffers the organic acids formed as … adroll_version = "2.0"; adroll_currency = "INR"; Ethylene Glycol or Propylene Glycol Based Antifreeze. The food grade formulations are Generally Regarded as Safe (GRAS) for use in the food and beverage industry where the possibility of incidental product contact exists or where a non-toxic coolant is mandated, with typical applications listed as follows; adroll_pix_id = "KAZWVOIGNJFDRDYYNILF3O"; Contain these corrosion inhibitors for ethylene glycol water is slightly acid that can eventually corrode system!
