Radiator coolants are specialized thermal-transfer fluids designed to prevent engine overheating in the summer and freezing in the winter. They consist of a mixture of water and glycols (ethylene or propylene), along with additives that protect the cooling system from rust, corrosion, and scale buildup. 

Coolant (or antifreeze) is a thermal-transfer fluid that prevents your engine from freezing in winter and overheating in summer. Modern formulations also include inhibitors to prevent rust, scale, and electrolysis within the radiator and engine block.

Industrial coolant oil is a specialized fluid used in machining processes—such as cutting, drilling, and grinding—to reduce heat, provide lubrication, flush away metal shavings (chips), and protect against corrosion. It extends tool life, improves surface finish, and prevents thermal distortion of the workpiece, making it essential for CNC, automotive, and heavy manufacturing industries.
