Product Description

Product Introduction

The HQ-EC2 series of engine coolant for fuel automobiles is composed of polyester grade ethylene glycol, compound anticorrosive additives, buffer, defoamer and water glycol, compound anticorrosion additives, buffer, defoamer and deionised water and deionised water. The freezing point of this product can be customised, the freezing point range is -60ºC~-20ºC; the operating temperature range is -60ºC~-20ºC. The freezing point range is -60ºC~-20ºC; the use temperature range is -55ºC~120ºC. The product is pre-diluted coolant and can be used directly. It is suitable for all kinds of diesel, gas and other heavy-duty automotive, marine and stationary units of the engine cooling system.
 

-The advantages of metal corrosion inhibition, in particular its unique aluminium-based metal protection, make it suitable for the protection of aluminium components in engine and cooling systems.

-It is suitable for the protection of aluminium components of the engine cooling system;
-Excellent anti-boiling, anti-freezing, anti-rust and anti-scaling properties for comprehensive protection of the engine cooling system;
-Excellent resistance to vibration cavitation, protecting wet cylinder liners from perforation erosion;
-Excellent resistance to hard water, preventing the cooling system from scaling caused by the loss of thermal conductivity;
Long-cycle corrosion protection for system metals, with a service life of up to 3 years or 150,000 kilometres;
-Meet the requirements of EU RoHS, REACH and other regulations.
