Antifreeze Products and Information

What is Antifreeze?

Antifreeze, also known as coolant, is a vital liquid substance added to a vehicle’s cooling system to lower the freezing point of the coolant while raising the boiling point to prevent overheating. It is used to prevent freezing and facilitate heat transfer in various environments, such as internal combustion engines and HVAC systems. Antifreeze also serves to protect your engine from corrosion, aids in heat transfer, and prevents rust and scale build-up over time.

At Synkhem, we offer a wide selection of antifreeze products, including Synkhem Premix G12, a ready-to-use formula ideal for modern engines, and Synkhem Antifreeze Concentrate 96%, which provides maximum flexibility for dilution based on your specific requirements.

The primary ingredient in most antifreeze is ethylene glycol, a type of alcohol with both a low freezing point and high boiling point, ensuring your vehicle is well-protected in extreme conditions.

Types of Antifreeze

There are various types of antifreeze, such as IAT, OAT, and HOAT, each offering different additives and inhibitors to provide protection against corrosion and other engine issues. Each type has a unique set of properties, such as a high heat capacity and low freezing point, enhancing the performance of antifreeze solutions. Some antifreeze products are sold as concentrated solutions, while others are ready-mixed for convenience.

Synkhem’s range includes both premixed solutions for immediate use and concentrated antifreeze that allows for flexible dilution ratios. For instance, our Synkhem Illumino 50 is a versatile product that ensures top-tier protection in cold and hot climates.

Antifreeze also comes in different colors, such as green and blue, which indicate the type of technology used. Modern cars often utilize Organic Acid Technology (OAT) antifreeze, which provides an extended service life of up to five years or 240,000 km (150,000 miles). Our Synkhem OAT antifreeze products are engineered for durability, offering long-lasting protection and performance.

How Antifreeze Works: The Science Behind Anti Freeze

Antifreeze works by lowering the freezing point of coolant and raising its boiling point, effectively preventing freezing in cold conditions and overheating in hot temperatures. The concentration of glycol in antifreeze plays a crucial role in its effectiveness. A higher glycol concentration ensures protection against freezing in extremely low temperatures, while a lower concentration is better suited to prevent overheating.

In addition to the temperature regulation, antifreeze contains additives that help protect your engine from rust and corrosion, lubricate the water pump, and prevent foaming. Synkhem antifreeze products, such as Synkhem Premix G12, are specifically formulated to offer both superior temperature stability and engine protection.

Importance of Antifreeze in Vehicles: Benefits and Risks

Antifreeze is vital for maintaining a properly functioning engine, especially during winter when temperatures drop below freezing. While antifreeze and coolant perform very similar functions, they are not the same in concentration and formulation. By lowering the freezing point of the water in the cooling system, antifreeze ensures that the system continues to work even in extreme cold. Additionally, it regulates the engine temperature to prevent overheating and shields against corrosion.

Without proper antifreeze levels, the cooling system could fail, leading to engine damage and expensive repairs. Choosing the right antifreeze from our Synkhem range ensures your vehicle remains protected, regardless of the conditions.

Maintenance and Replacement of Antifreeze

It’s essential to check the engine coolant level at least twice a year, particularly before the summer and winter months. The coolant should be topped up whenever it falls below the recommended level, or if a warning light appears on your dashboard. To ensure maximum effectiveness and protection, a full system flush is recommended when replacing antifreeze.

The lifespan of antifreeze depends on several factors, including the concentration of glycol, the type of antifreeze used, and the vehicle's operating conditions. Synkhem offers high-quality antifreeze products that provide long-lasting protection, ensuring optimal performance throughout the year.

Corrosion Inhibitors in Antifreeze: Protecting Your Engine

Most commercial antifreeze formulations include corrosion inhibitors and a colored dye for easy identification. These inhibitors protect metal parts, such as aluminum, from rust and corrosion, ensuring the antifreeze flows properly and maintains your engine's function. Older inhibitors like silicates and phosphates were common in the past, but modern vehicles use organic acid technology (OAT) or hybrid organic acid technology (HOAT) formulations for better, long-lasting protection.

Synkhem’s advanced antifreeze formulations, offer superior corrosion resistance, ensuring your engine stays protected.

Antifreeze Colors and What They Mean

Antifreeze comes in various colors, which may indicate the type of technology used, such as IAT, OAT, or HOAT. However, color alone is not a reliable indicator of compatibility with your vehicle’s cooling system. It’s crucial to consult your vehicle’s owner’s manual or a trusted mechanic to ensure the right type of antifreeze is selected.

Our Synkhem OAT Antifreeze is compatible with modern cooling systems and provides extended protection, making it an excellent choice for long-term engine care.

Industrial Uses of Antifreeze: Beyond Automotive

Antifreeze is widely used in industrial applications beyond automotive. In electronics cooling, it helps prevent overheating and corrosion, particularly with mixtures of water and either ethylene glycol (EGW) or propylene glycol (PGW). Antifreeze also plays a critical role in industries such as aerospace and construction, preventing freezing and corrosion in various systems.
