DER SCHUTZ-GARANT

In order to improve fuel economy and reduce emissions of combustion engines, smaller, lighter and hotter engines are being developed. New construction materials are being used in the manufacture of the engine cooling system. Other drivers are legislative requirements (e.g., REACH) regarding the components used in the final product. As a result, problems are observed in modern engine coolant systems, e.g., deposits, reduced functionality of the heat exchanger and increased corrosion. This requires new breakthrough technologies when it comes to future engine coolant solutions.

GLYSANTIN^® G64^® and GLYSANTIN^® G65^® not only exceed all technical requirements and fulfill the demanding legislative requirements but also sets a new benchmark for the sustainable protection of modern engines.

Hybrid powertrain technologies represent the most complex challenge from a thermal management point of view. The internal combustion engine (ICE) requires coolants with excellent heat transfer properties while the power electronics, the electric engine, and the battery pack will operate at significantly lower temperatures. Here, coolants with a broad thermal functionality window are the key. 

Products such as GLYSANTIN^® G30^®, G34^®, G40^®, G64^® and G65^® work effectively in a broad temperature window, allowing for outstanding heat transfer and corrosion protection in the high temperature cooling circuit of the ICE as well the low temperature cooling circuit for the battery pack.

Many of BASF’s traditional coolant products are already successfully used in battery electric vehicles.
Products such as GLYSANTIN^® G30^®, G34^®, G40^®, G64^® and G65^® help to keep battery electric vehicles in their ideal thermal window and enable optimum driving range. These products do not only offer excellent stability at high temperatures, but they also effectively prevent corrosion in a broad temperature window. As a result, good passivation is achieved in the low temperature cooling circuits for the battery pack as well as in circuits of higher temperatures, e.g., for the electric engine.

GLYSANTIN^® G22^® ELECTRIFIED^® is BASF's first premium engine coolant developed specifically for indirectly cooled BEV. The ready-to-use coolant delivers a low electrical conductivity and maintains low and stable currents when exposed to a voltage source. This translates into low fluid decomposition and low generation of hydrogen, making it a safety optimized product, while ensuring optimal corrosion protection.
