What is Organic Acid Technology (OAT) primarily based on?

Organic Acid Technology (OAT) is primarily based on organic acid inhibitors. This technology employs organic acids, often in combination with specific corrosion inhibitors, to provide effective protection against corrosion in engine cooling systems. OAT fluids are formulated to deliver long-lasting protection without the need for traditional inorganic additives found in older coolants.

The use of organic acids allows for reduced scaling and improved thermal conductivity, making OAT as a modern alternative to previous coolant technologies like conventional ethylene glycol-based formulas. These organic inhibitors help to passivate metal surfaces, forming a protective layer that guards against rust and other forms of corrosion while also offering better durability, often extending the service interval longer than traditional coolant mixtures. This principle distinguishes OAT from other additive types such as those based on mineral additives or conventional antifreeze compounds.
