HYDRAULAN

Pioneering Brake System Safety

With the know-how of our chemists and technicians, BASF has been
setting the market standard of brake fluids for more than 60 years.
BASF was the first company to develop a low viscosity DOT 4 brake
fluid, specifically for modern braking systems with electronic control
systems such as ESP®/DSC, ABS and ASC.
Together in partnership with both, automobile manufactures and
OEM suppliers and as amember of the industry standards association we
continue to developand improve HYDRAULAN® brake fluids to meet
both the current and future needs of the industry, and maintain the
highest safety requirements demanded by customers.

HYDRAULAN® premium brake fluids and OEM approvals

To ensure trouble-free functioning of the braking system when a vehicle is in constant use, the automotive industry sets very high standards for the hydraulic fluids. BASF has been a competent and reliable partner of the automotive industry and develops products designed to meet the highest quality standards. But BASF also works with the professional industry associations that set these standards

HYDRAULAN® brake fluids exceeding the DOT 4 standards are officially approved by the automobile manufacturers listed in the above table.

HYDRAULAN® 404

In the field of brake fluids BASF has developed a groundbreaking innovation! HYDRAULAN® 404 is a tailor-made brake fluid for vehicles with electronic stability control systems (ESP® and DSC).
At low temperatures this brake fluid has an extremely low viscosity.
This enables pressure to build up more quickly and the wheelbrakes to respond more quickly.
Thus the pressure buildup at low temperatures of approx. –20°C is about 30% faster than with conventional DOT 4 brake fluids, so the high safety potential of ESP® or DSC can be used to the full in winter road conditions. HYDRAULAN® 404 exceeds the new ISO 4925, Class 6 specifications and impresses with a boiling point of at least 265°C, a wet boiling point of at least 175°C and a viscosity at –40°C of no more than 700mm2/s HYD.

HYDRAULAN® 406 ESI

Continuing to build on our long-established close partnership with the automotive industry, BASF’s latest innovation HYDRAULAN® 406 ESI sets new performance parameters for a premium brake fluid.
Enhanced safety is 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 NON-SILICONE BASE and also exceeds international requirements for low viscosity brake fluids. 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.
