Chemicals/substances that are added to coolant during manufacturing to enhance its performance and provide additional benefits are coolant additives. Coolants control engine temperature, ward off overheating, and, when combined with additives, shield the engine from corrosion, cavitation, and fouling.

Automotive coolants consist of a mixture of antifreeze with additive packages and water. Be it water or antifreeze, they are corrosive and degrade the metal system. This can be controlled using coolants incorporated with various additives like corrosion inhibitor, antiscalant, biocide, antifoam, etc.

The efficiency and performance of a coolant are evaluated on following factors.

  • Heat Transfer Rate: Enhances heat transfer, aiding engine temperature control and overheating prevention.
  • Corrosion and Rust Formation: Coolants with corrosion inhibitors create a shield of defense on the metal surfaces, halting the development of rust and extending the lifespan of the apparatus.
  • Foaming Factor: Reduces the amount of foam that forms inside the coolant. Foam can obstruct heat transfer, which makes the coolant less effective at cooling the engine.
  • Cavitation: Anti-cavitation compounds in coolants help prevent damage caused by cavitation. They counteract the formation of harmful bubbles that corrode metal surfaces and reduce wear on cooling system components.

Coolant additives address fouling, stability, and more, ensuring reliable machinery operation, boosting productivity, and lowering maintenance costs—critical for industrial efficiency.

Coolant Additives Range

Corrosion Inhibitor: Corrosion inhibitors are crucial in coolant formulas, safeguarding essential components from rust and ensuring long-lasting cooling system reliability. They create a protective barrier on metal surfaces, mitigating the effects of corrosion and erosion, thus preserving peak performance.

Antiscalant: Essential in coolant solutions, antiscalant deter scale formation within cooling systems. By preventing the accumulation of mineral deposits, these additives play a critical role in preserving the efficiency and functionality of equipment, such as radiators and heat exchangers.

Antifoam: Crucial in coolant formulations, antifoam agents combat foam formation during the cooling process. By effectively suppressing foam, these additives enhance system efficiency, prevent potential damage to components, and ensure a consistent and smooth coolant flow.

Thickener: In the realm of coolant additives, thickeners contribute to viscosity and stability. These agents enhance the thickness of the coolant, improving its adherence to surfaces and optimizing its performance in heat dissipation and protection of the cooling system.

Biocide / Preservative: In coolant formulations, biocides act as guardians against microbial contamination. By controlling the growth of bacteria and other microorganisms in the coolant, these additives maintain water quality, prevent fouling, and extend the life of the coolant and associated components.
