Enhanced Safety Intelligence (ESI)

Brake fluids are a crucial safety factor – they must ensure fast signal processing and breaking reactions. A low viscosity is crucial here. With a viscosity that is more than 50% lower than standard products, and exceeds international requirements, BASF's brake fluid for enhanced safety intelligence, HYDRAULAN® 406 ESI, significantly improves braking safety – even under difficult conditions. 


Enhanced safety is also provided by the product’s higher boiling points and its reduced low temperature viscosity. HYDRAULAN® 406 ESI is a brake fluid that covers all the specifications of DOT 3, DOT 4, DOT 5.1 NONSILICONE BASE and SAE J 1704 Low Viscosity. 


With the continuing technological advancement of brake systems and automated safety systems, lubricity will become an essential factor when selecting an appropriate brake fluid. Here, HYDRAULAN® 406 ESI has been formulated to provide superior lubrication and therefore extend the durability of the whole brake system.

Components for Lubricants



Ester Basestocks

Fluids for e-vehicles require different base oil concepts to meet low viscosity targets, improved thermal and oxidative stability and electrical conductivity.

SYNATIVE® ester base oils can help to meet future requirements, providing

  • Low viscosities
  • Superior thermal and oxidative stability
  • Excellent thermal and dielectrical properties
  • Non-toxicity, biodegradability and up to 100% renewable feedstocks
  • Low volatility

Ester base oils are the most versatile type of base oil technologies and can be tailored to your specific needs. With our ester base oils, we are offering a broad and diverse synthetic base oil portfolio with a unique combination of properties required for future e-fluids and a wide variety of ester technologies. Our ester base oils are ideal for formulating next generation motor, e-axle and gearbox fluids and lubricants for electric vehicles.


Polyalkylene Glycols

Fluids for e-vehicles require different base oil concepts to meet low viscosity targets, improved thermal and oxidative stability and electrical conductivity.

BREOX® polyalkylene glycols (PAGs) can help to meet future thermal management requirements, including

  • High heat conductivity for improved thermal management
  • Ultra-low friction coefficients for high efficiency
  • Low wear scar for optimal equipment protection

Low viscosity Polyalkylene Glycols offer high performance and desired properties to develop future e-fluids and can be used to formulate next generation e-motor, e-axle and gearbox lubricants. PAGs can enable features such as higher mileage and protection of batteries as well as long lasting equipment lifetime and fill for life requirements. With our broad portfolio of water soluble and water insoluble PAGs combined with strong expertise in tribology and chemistry, we are committed to support you to solve current and future technical challenges.


Refrigeration Esters

Depending on the e-vehicle design, air conditioner compressors can also be used for heating and supportive direct and indirect battery cooling.

SYNATIVE® refrigeration esters as base oils in A/C compressor lubricants can help to improve overall thermal management and deliver

  • Battery efficiency if A/C is used for the entire thermal management in the car
  • Support of direct or indirect cooling/heating of the battery by providing high energy efficiency

BASF's refrigeration esters deliver superior performance, excellent hydrolytic and oxidative stability also under severe operation conditions and can contribute to high battery efficiency and improved thermal management of e-vehicles. Our solutions can be customized and tailored to your specific needs.


Energy Efficiency Booster (EEB)

Friction performance of transmission fluids can significantly contribute to reduced CO2 footprint of e-vehicles.

SYNATIVE® EEB technology can help to meet CO2 targets by enabling

  • Improved friction performance of a transmission oil
  • Compatibility with low viscosity Group I to Group IV oils
  • High heat conductivity

BASF has developed a novel base stock technology with unique polyether-based hybrid structure. Parts of the molecular structure contribute to outstanding frictional behavior, exceeding PAO performance, while other parts help to achieve compatibility with hydrocarbon oils. The new high-performance technology can be used in various automotive applications, including transmission lubricants, gear oils and greases and enable potential CO2 savings and improved thermal management.


Metal deactivators to prevent copper corrosion

Depending on the driveline concept, copper windings are immersed permanently into the lubricant: Excellent corrosion protection is needed.

IRGAMET® yellow metal corrosion protection additives can help to meet future requirements as, for examaple, excellent copper corrosion protection in ASTM D130 even at elevated temperatures.

Leveraging its technical expertise and application know-how, BASF is a competent partner to identify optimum corrosion protection and manage regulatory profile of every e-driveline lubricant.
