JEFFCOOL

THERMOGUARD

ThermoGuard Universal Extended Life Antifreeze/Coolant incorporates cutting-edge inhibitor technology. It utilizes a hybrid organic acid technology (HOAT) additive/inhibitor package and contains no phosphates, borates, nitrates, or silicates. ThermoGuard Universal Extended Life Antifreeze/Coolant incorporates multiple complex carboxylic acid derivatives along with nitrite to protect all six standard metal alloys (brass, copper, steel, solder, cast iron, and aluminum). These low foaming carboxylates not only provide broad-range metal protection but also guard the cooling system against corrosion and cavitation-erosion. In addition it contains additive to minimize hot surface scaling while also preventing heat transfer surface fouling due to minor oil leakage.
