Preventing Corrosion in Liquid Cooling Systems

Corrosion Caused by Uninhibited Ethylene Glycol. Studies 1 show that uninhibited ethylene glycol will degrade into five organic acids - glycolic, glyoxylic, formic, carbonic, and oxalic - in the presence of heat, oxygen, and common cooling system metals such as copper and aluminum. Copper and aluminum act as a catalyst in the presence of uninhibited ethylene glycol.
