Audited Supplier Fully Organic Engine Coolant Additive Package
Introduction
This series of products is an environmentally friendly organic carboxylic acid series coolant additive designed specifically to meet the automotive technology needs of Europe, Asia, and North America. It is composed of L30 engine coolant composite additives and H30 heavy-duty engine coolant composite additives.
Adopting the international cutting-edge organic carboxylic acid long-term protection technology.
Through the synergistic effect of various organic carboxylic acid corrosion inhibitors, a dense protective film is formed on the metal surface, providing the best rust and corrosion protection for all metal materials in the cooling system.
On the basis of L30, H30 combines efficient anti cavitation suppression technology to provide more effective protection for wet cylinder liners of heavy-duty vehicles.
Has excellent corrosion and scale resistance performance, making production simple and easy to operate
Applications
HQT-L30 and HQT-H30 are used to prepare ethylene glycol and propylene glycol engine coolant concentrate solution.
HQT-L30 is suitable for cooling systems of light load engines in various passenger cars, small and medium-sized commercial vehicles, and for long-term use in heavy-duty diesel engines with high enhancement coefficient wet cylinder liners.
HQT-H30 is more suitable for long-term use in heavy-duty diesel engines with high enhancement coefficient wet cylinder liners.
