[Product Introduction] 

Leierfu long-acting anti-freezing solution is refined with high-purity polyester grade ethylene glycol, purified water and a variety of efficient composite additives. It is the best protective agent for the cooling system of internal combustion engine. With low freezing point, small viscosity, low-temperature flow and good thermal conduction, it may effectively prolong the service life of the cooling system. 

[Functional Characteristic] 

With good anti-scaling, anti-corrosion, anti-cavitation performance, it may protect the iron parts inside the water tank from corrosion; 

With the excellent high-temperature cooling effect, it may sufficiently guarantee the heat transfer performance of anti-freezing solution and high-speed moving parts; 

Dense oxide film will be formed on the metal surface, which may effectively restrain the electrochemical corrosion of the cooling system; 

With the general use in four seasons (freezing resistance in winter and boiling resistance in summer), it is suggested to use in the whole year to protect the vehicle's cooling system. 

[Recommended use] 

It is applicable to the engine coolant circulating cooling system for cars, light and heavy-duty diesel vehicles, engineering machinery, etc. It may provide the excellent corrosion resistance to the metal parts of the cooling system. It may be used in four seasons.
