Engine Coolant Additive

​

Engine coolant additives are essential for protecting the entire cooling system of internal combustion engines. They ensure efficient heat transfer, corrosion prevention, and extended component life. LubriChemical USA provides high-performance coolant additives formulated for both light-duty vehicles (cars, SUVs, motorcycles) and heavy-duty applications (trucks, buses, agricultural and industrial equipment).

Our formulations are developed using advanced additive technologies, including:

• OAT (Organic Acid Technology) – long-life organic inhibitors designed for modern engines that require extended drain intervals.

• HOAT (Hybrid Organic Acid Technology) – a hybrid formulation combining silicates with organic acids for enhanced durability.

• Si-OAT (Silicated Organic Acid Technology) – ideal for high-performance aluminum engines, delivering fast-acting protection and extended service life.

These coolant additives help prevent:

• Corrosion and electrolysis,

• Scale formation,

• Overheating under extreme operating conditions,

• Cavitation in high-load diesel engines.

LubriChemical USA’s coolant additive line meets international performance standards and is suitable for gasoline, diesel, hybrid, and turbocharged engines. Designed to maintain thermal stability, maximize cooling efficiency, and extend the life of water pumps, radiators, hoses, and metal surfaces, our formulations provide reliable protection for both light-duty and heavy-duty fleets.
