BONDERITE Bridge Technology (Formerly known as BONDERITE Two-Step Process/Flex)

Nowadays, automotive manufacturers are re-examining every aspect of a vehicle to ensure compliance with the 2025 Corporate Average Fuel Economy standards, which explains the lightweighting trend. After all, reducing a vehicle’s weight by just 10 percent can improve fuel economy by 6-8 percent.

Mixed materials play a key role in weight reduction. At Henkel we are ready to help you increase the use of alternative substrates with weight-saving properties for every part of a vehicle – from the powertrain/chassis to the body-in-white. 

The Flexible Weight-Saver

Zirconium-Based Pretreatment for a Metal Mix up to 85%* Aluminum

The BONDERITE Bridge Technology enables vehicle lightweighting by processing a metal mix of up to 85* percent aluminum. A zinc phosphate coating (with or without Nickel) is applied on cold-rolled steel and zinc-coated substrates, while a zirconium-based coating is applied on the aluminum surfaces.  Easily integrated into existing production lines without cost-intensive modifications, the zirconium-based pretreatment for aluminum gives you flexibility in your paint shop operation and a variety of benefits.

How You Benefit

  • Allows for a reduction in vehicle weight
  • Improves fuel economy
  • Enables a metal mix of up to 85% aluminum to be processed via a traditional zinc phosphate
  • Saves process costs compared to standard aluminum phosphating
  • Selective deposition on each substrate: zinc phosphate on CRS, EG and HDG, zirconium-oxide on Aluminum*
  • Excellent corrosion performance on all substrates
  • Less sludge generation
  • Existing phosphate systems convertible with minimal cost and downtime

*CRS: Cold-Rolled Steel, EG: Electro-Galvanized, HDG: Hot Dipped Galvanized
