Propylene Glycol Corrosion Inhibitor

Corrosion Inhibitor for PG based systems is a specially formulated multi-metal corrosion inhibitor, preventing corrosion in multiple ways. It modifies the metal surface by absorption, making it less susceptible to corrosion. It buffers the organic acids formed as a result of glycol/ water oxidation, preventing further formation of acids. The corrosion inhibitor protects metal surfaces from corrosion without reducing the system’s heat transfer efficiency. Addition of corrosion inhibitor prevents copper and cu-alloys corrosion, corrosion on aluminum, steel and cast iron. It is well compatible with seals, o-rings, rubber hoses and other radiator engine components, improved closed loop system longevity and performance.

Metal acts as catalyst in un-inhibited glycol solution for the formation of these acids, which then chemically attacks and corrodes system. 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. It is a broad spectrum corrosion inhibitor that improves metal surface by absorption and making it less vulnerable to corrosion. It is compatible and fully functional in glycol-water & glycol-ethanol (rectified spirit) mixtures and improves heat transferability.

Glycol in presence to heat and air degrades into five organic acids namely, Glycolic Acid, Glyoxalic Acid, Formic Acid, Carbonic Acid & Oxalic Acid
