What is Antifreeze, What are its Features?

   Antifreeze provides support to prevent problems such as corrosion, rust and wear in the vehicle. Antifreeze, which is a life saver for vehicle engines, raises the boiling point and lowers the freezing point when added to the coolant. It is used in the radiator of the vehicle by mixing it with water in a certain ratio (the recommended amount for stable efficiency is 50% antifreeze – 50% water).

How is Antifreeze Selection Made?

   There are 4 types of antifreeze: Inorganic Additive Technology (IAT), Organic Acid Technology (OAT), Hybrid Organic Acid Technology (HOAT), Phosphated, Hybrid Organic Acid Technology (P-HOAT).

   The choice of antifreeze is a misunderstood method, although it is mostly made according to its colors. Antifreezes are actually produced as colorless, but the reason for giving color is to distinguish the antifreeze in case of any malfunction or leakage. It is usually available in green, orange, yellow, blue or pink. Each color represents its level of productivity.
Blue antifreeze is produced by adding inhibitors with classical production technology. Because it is generally affordable, blue antifreeze is generally preferred in old and economical vehicles. Red antifreeze, on the other hand, is antifreeze produced with OAT, that is, organic-based acid. It is the most widely used type of antifreeze. It has a low freezing point. It is preferred in regions with harsh winters. It is used in diesel and LPG vehicles. Red antifreeze containing organic inhibitors lasts 3 times longer than blue antifreeze containing conventional inhibitors.

   Another of the antifreeze colors is the green one. Green colored antifreezes are inorganic, but they are very effective in calcification and freezing. Thanks to its content, it minimizes calcification and freezing. It has a strong protection feature, but it cannot be said to be very long-lasting.
