It treats the surfaces of the metal making them less susceptible to corrosion. 1 gallon of ChemWorld SR1 will protect 140 gallons of 20% glycol solution from corrosion. RhoTherm™ 921 Inhibited Ethylene Glycol RhoTherm™ 921 Ultra . ChemWorld SR1 Glycol Corrosion Inhibitor. Chemtex’s Coolant Corrosion Inhibitor is a specially formulated (nitrite free) chemical additive for Mono Ethylene Glycol to protect system metals from corrosion. We are 100% internet based and focus on SEO to provide easy to find, easy to locate specialty chemicals and related feed equipment at competitive pricing. All-Organic Inhibitors These blended inhibitors can replace typical nitrite and molybdate based treatment programs. Inhibitors. Because glycols without a corrosion package are more corrosive than water it is strongly recommended to order glycols with the corrosion inhibitor package. Chemtex's Propylene Glycol Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. It is only the corrosion inhibitors that are added to the glycol that protect the metal. Food Grade organic inhibitors are recommended for use with Food Grade Propylene Glycol when there is a potential for beverage or food contact. 2 gallons is enough chemical to use to convert one 55 gallon container from just propylene glycol to corrosion inhibited propylene glycol. Potentiodynamic polarization tests were carried out to study the effect of each chemical. The corrosion inhibitors cover a wide range of uses including the typical metals such as carbon steel … 55 gallons of ChemWorld SR1 will protect 7600 gallons of 20% glycol solution from corrosion. 55 gallons converts 1,540 gallons of pure 99.9% Propylene Glycol into a 95% solution of Inhibited Propylene Glycol. Uninhibited glycol is very corrosive to system metals, so the glycol fluids being used must be inhibited with the appropriate corrosion inhibitors. Three types of corrosion inhibitors consisting of sodium diphosphate (Na2H2P2O7), sodium benzoate (NaC7H5O2), and sodium tetraborate (Na2B4O7) were evaluated to analyze their effectiveness to inhibit the aluminum alloy 3303 (UNS A93303) against corrosion, in water-ethylene glycol (C2H6O2) mixture. There is no minimum order size. The proprietary industrial inhibitor packages used in DOWTHERM™ SR-1 ethylene glycol and DOWFROST™ and DOWFROST™ HD propylene glycol are specially formulated to help prevent corrosion in two ways. We deliver to clients across Canada, with your order shipped in 3-4 business days. ChemWorld is also a distributor of dipropylene glycol and other specialty chemicals. Our Main customer base is in the USA, but we are expanding more world wide everyday. Propylene glycol, Ethylene glycol and closed loop corrosion inhibitors can be purchased on-line through our secure on-line Store. These inhibitors prevent corrosion of metals in two ways. It buffers the organic acids formed as a result of glycol oxidation and prevents further formation of acids. For food and beverage facilities applications, use. All the components necessary for complete system protection make these products an economical choice for use in both hot water and chilled water applications. Both products are comprised of a USP-Certified (food-grade) base propylene glycol and a proprietary food-grade corrosion inhibitor package. These products provide improved corrosion control under static conditions, are less abrasive to pump seals because of the lower solids contribution to the treated solution, and offer reduced potential for microbiological activity. 0.005% dilution rate. Glycol Antifreeze Inhibitor WM8703 is formulated to provide a large excess of buffering capacity as well as inhibit corrosion. It buffers the organic acids formed as a result of glycol oxidation. The fluid is dyed fluorescent orange to operating temperature range of -60°F to 350°F (-51°C to 177°C) and ... Inhibitor levels in glycol solutions less than 25-30% may not provide adequate corrosion protection. Molybdate Based Inhibitors  Molybdate is the main component that provides primary corrosion control. This product is NOT approved for use in Food and Beverage facilities. Mono Ethylene Glycol Corrosion Inhibitor Chemtex's MEG Corrosion Inhibitor is a specially formulated chemical additive designed to prevent corrosion in multi-ways. RhoTherm™ 921 Ultra is a virgin ethylene glycol antifreeze and heat transfer fluid specially blended with non-phosphate corrosion… inhibitor, Rhomar Water’s Pro-Tek® 921. Glycol based systems, using Propylene Glycol or Ethylene Glycol, without any corrosion inhibitors or additives, are more corrosive and aggressive than water alone. Protect your heating system against scale and corrosion extending the life of your central heating system. Yellow metal inhibitors are built into many of our formulations, however, some severe service systems will require additional corrosion control specifically directed at copper and copper alloys. We provide consultation at no cost on proper chemical selection and equipment needs. Reactions with dissolved oxygen can lead to the formation of organic acids that attack unprotected metal surfaces. 1 gallon converts 28 gallons of pure 99.9% Propylene Glycol into a 95% solution of Inhibited Propylene Glycol. It buffers the organic acids formed as a result of glycol oxidation. Closed loop inhibitor formulations are available from the three basic categories:  Nitrite based formulations, low-solids Molybdate blends, and the All Organic or Food Grade corrosion inhibitors. Our goal is to make it easy for customers to find and purchase our products. This makes the surface less susceptible to electrochemical attack. One disadvantage of phosphate is precipitation with calcium in hard water, which is one reason that deionized water is … Corrosion inhibitors can be added to water based coolants to help prevent corrosion. machine or a high pressure washer the maximum dilution is 1:200 or Especially useful in all copper or copper alloy systems where a low solids treatment is required. By contrast, corrosion inhibitors are gradually used up, and must be replenished from time to time. This protect may be ordered in clear or in pink form. Your On-Line Source for propylene glycol, ethylene glycol, corrosion inhibitors and buffer solutions. ChemWorld SR1 Glycol Corrosion Inhibitor is a concentrated corrosion inhibitor designed for glycol system that need corrosion resistance protection. It treats the surfaces of the metal making them less susceptible to corrosion. This … Since the surface tension of a glycol & water mixture is lower than with water, layers of rust can be dissolved easily, uncovering fresh metal surfaces that can be oxidized again, and the corrosion process will cause significant damage to the HVAC piping system. It is colorless, odorless and hygroscopic in nature. ChemWorld has three distribution hubs located in Salt Lake City, Utah, in Taylor, Michigan and Atlanta, Georgia. pH Buffers are used to help counteract this pH change, and inhibit glycol oxidation reactions. For applications where there is no potential for food or beverage contact, our formulations will include azoles for yellow metal protection and dispersants for improved deposit control. Offer an alternative to mixing solutions on site Dowtherm SR-1 and Water, is a mixture containing 45% RO water, and 55% Dow SR-1 Inhibited Ethylene Glycol (5 gal). Glycol based systems, using Propylene Glycol or Ethylene Glycol, without any corrosion inhibitors or additives, are more corrosive and aggressive than water alone. Add to Cart. Diethylene glycol (DEG) refers to an organic chemical compound with the chemical formula (HOCH 2 CH 2) 2 O.
