Chemtex’s MEG (Ethylene Glycol) Brine Corrosion Inhibitor is a specially formulated chemical compound designed to prevent corrosion in multi-ways. MEG (Ethylene Glycol) Brine Corrosion Inhibitor treats the surfaces of the metal making them less susceptible to corrosion. MEG (Ethylene Glycol) Brine Corrosion Inhibitor buffers the organic acids formed as a result of glycol oxidation. Inhibited (MEG) glycol based heat transfer fluids provides corrosion protection without reducing system’s heat transfer efficiency.

It is very important to use corrosion inhibitor in glycol system to prevent degradation of glycol. MEG in presence to heat and air degrades into five organic acids viz., Glycolic Acid, Glyoxalic Acid, Formic Acid, Carbonic Acid & Oxalic Acid. Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system.
