On the other hand, red coolant, also known as organic acid technology (OAT) coolant, uses organic acids to prevent corrosion. The main difference between these two types of coolants is the type of corrosion inhibitors they use.
Corrosion Inhibitors and Their Role
Corrosion inhibitors are chemicals that are added to coolants to prevent corrosion in the engine and other metal components. In green coolant, silicates and phosphates are used as corrosion inhibitors. These chemicals work by forming a protective layer on the surface of metal components, preventing corrosion from occurring. In red coolant, organic acids such as sebacate and 2-ethylhexanoic acid are used as corrosion inhibitors. These organic acids work by binding to metal ions and preventing them from reacting with oxygen, which can cause corrosion.
The use of different corrosion inhibitors in green and red coolant means that they have different properties and characteristics. For example, green coolant is more effective at preventing corrosion in high-temperature applications, while red coolant is more effective at preventing corrosion in low-temperature applications. Additionally, green coolant is more compatible with certain types of metals, such as aluminum and copper, while red coolant is more compatible with other types of metals, such as steel and iron.
Potential Risks of Mixing Green and Red Coolant
Mixing green and red coolant can be risky because of the different corrosion inhibitors they contain.
