It is also a very good buffer for pH control. Lastly, never use automobile anti-freeze in a non-automotive application. In the absence of leaks, antifreeze chemicals such as ethylene glycol or propylene glycol may retain their basic properties indefinitely. The anti-freeze solutions have lower viscosity than an antifreeze solution prepared with the same weight percent water but lacking any glycerin. Glycol based systems, using Propylene Glycol or Ethylene Glycol, without any corrosion inhibitors or additives, are more corrosive and aggressive than water alone. Corrosion problems with ethylene glycol/water mixtures can be minimized or eliminated by using ethylene glycol that contains inhibitors. Especially useful in all copper or copper alloy systems where a low solids treatment is required. It is a multi-metal corrosion inhibitor and prevents corrosion in multi-ways. Food Grade organic inhibitors are recommended for use with Food Grade Propylene Glycol when there is a potential for beverage or food contact.

ChemWorld SR1 Glycol Corrosion Inhibitor is a concentrated corrosion inhibitor designed for glycol system that need corrosion resistance protection. All the components necessary for complete system protection make these products an economical choice for use in both hot water and chilled water applications. 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. Reactions with dissolved oxygen can lead to the formation of organic acids that attack unprotected metal surfaces. 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 buffers the organic acids formed as a result of glycol oxidation. ChemWorld SR1 Glycol Corrosion Inhibitor. Copyright © 2021 Vedra Industries. There is no minimum order size.
