AQUENT P-OAT is a phosphate-based Organic Acid Technology (Phosphate OAT), also known as Hybrid Organic Acid Technology (HOAT) in the U.S. market. It is specially formulated for all Asian vehicles using “blue” antifreeze/coolant. AQUENT P-OAT is free from silicates, borates, nitrites, and amines, ensuring safe and effective protection. It is important not to mix AQUENT P-OAT with other coolants, especially silicate-based ones, as this could result in gel formation and radiator clogging.
