The Chemical Composition of Green Antifreeze

The composition of the green coolant differs from other types commonly used in vehicles.

Understanding its chemical makeup is crucial in determining its compatibility with different metals and understanding its toxicity.

Here are the key components of green antifreeze:

• Ethylene glycol: This is the main ingredient in green antifreeze and is responsible for its ability to lower the freezing point of water. It is highly toxic and can be deadly if ingested, so care must be taken when handling it.
• Silicates: These are added to green antifreeze to help protect metal surfaces from corrosion. They work by creating a protective layer on the metal that prevents oxidation and rust.
• Borates: These are also added to green antifreeze to help prevent corrosion. They work by neutralizing acids that can form in the coolant system.
• Phosphates: These are used in some green antifreeze formulations to help prevent scale buildup in the cooling system.
• Dyes: These are added to give the coolant its distinctive green color.

When it comes to green antifreeze, it is important to note that it is not compatible with all metals. In particular, it should not be used in aluminum engines or radiators, as it can cause corrosion.

The Chemical Composition of Orange Antifreeze

Get ready to learn about the unique chemical makeup of the coolant with the orange hue, orange antifreeze.

This type of antifreeze is typically made up of a combination of organic acid technology (OAT) and hybrid organic acid technology (HOAT).

OAT is a newer technology that uses organic acids such as sebacic acid and 2-ethylhexanoic acid, while HOAT is a combination of OAT and inorganic additives.

As you can see, orange antifreeze typically contains higher levels of sebacic acid and 2-ethylhexanoic acid, which are key components of OAT technology.

Additionally, orange antifreeze often contains less silicates and phosphates, which are commonly found in green antifreeze.

When it comes to performance, orange antifreeze has several advantages. It typically offers longer-lasting protection against corrosion and better compatibility with other fluids such as diesel exhaust fluid (DEF) and oil.

It’s important to note that not all orange antifreeze is compatible with all types of engines and vehicles.
