Advanced Inorganic Low-Silicon Engine Coolant Additive Liquid Solution for Efficiency

LE32/HE32 Inorganic Low-silicon Engine Coolant Additive Package/antifreeze additive

Description
This series of products consists of HQT-LE32 light load engine coolant additive package and HQT-HE32 heavy load engine coolant additive package.
Adopting internationally advanced low silicate protection technology, technical improvements and quality upgrades have been made to similar international products.
Made using efficient corrosion inhibitor technology combined with advanced inorganic corrosion inhibitors. The combination of dual anionic silicon stabilizers and efficient corrosion inhibitors effectively prevents the formation of silica gel precipitation, providing first-class rust and corrosion protection for all metal parts in cooling systems, especially cast iron, steel, copper, solder, aluminum, and aluminum alloys.
HQT-HE32 combines efficient anti cavitation suppression technology on the basis of HQT-LE32 to provide effective protection for wet cylinder liners of heavy-duty vehicles.
It has excellent corrosion resistance and scale inhibition performance, and is easy to produce.

Applications
HQT-LE32 and HQT-HE32 are used to mix ethylene glycol and propylene glycol engine coolant concentrates.
HQT-LE32 is suitable for cooling systems of light load engines in various passenger cars, small and medium-sized commercial vehicles, etc.
HQT-HE32 is suitable for various high-performance diesel engines such as passenger cars, commercial vehicles, mining vehicles, engineering machinery, generator sets, and other wet cylinder liner heavy-duty cooling systems.
