Engine Antifreeze

Engine Antifreeze is available in ethylene glycol–based and propylene glycol–based formulations, supplied as concentrated or premixed (ready-to-use) products. Common technologies include IAT (Inorganic Additive Technology), OAT (Organic Acid Technology), HOAT (Hybrid OAT), and Si-OAT, each tailored to specific engine designs and OEM requirements. Typical components include glycol for freeze and boil protection, corrosion inhibitors, anti-foaming agents, stabilizers, dyes for leak detection, and deionized water in premixed versions. Engine antifreeze is widely used in passenger cars, heavy-duty trucks, buses, generators, agricultural machinery, construction equipment, and stationary engines, providing protection for aluminum, copper, cast iron, rubber hoses, and seals.
