Schwalbach, Germany -- Dow Automotive Systems is the adhesives partner in a project called "Light-eBody" for bonding heterogeneous body components together.
This joint research project, initiated and funded by the German Bundesministerium für Bildung und Forschung, aims to develop new lightweight body concepts for future electric vehicles.
Dow Automotive Systems has already supported several R&D projects, using the company's considerable know-how in bonding technologies.
Since the introduction of bonded windshields in the early 1970s and the first bonded body structures, Dow Automotive Systems claims it has been "a reliable and innovative partner for all aspects of bonding technologies."
Now, as electric vehicles are being widely developed, bonding technologies are becoming more and more important. Bonding was initially a safety solution, as bonded body structures provide a longer lifetime cycle and improve the absorption of crash energies.
But with the rise of e-mobility, bonding for lightweight structures is essential with increasing use of heterogeneous materials which often cannot be joined in a traditional manner, Dow says.
As a result, bonding technologies support essential material compounding for lightweighting, needed to reach a higher mileage and saving battery costs.
For lightweight bonding, Dow's Betamate and Betaforce adhesives are used, which can be delivered with several formula characteristics. In the future, new MMA adhesives will complement the company's portfolio.
Betaforce is a PU adhesive with prolonged working times, quick adhesion, and little surface preparation requirements, is especially suitable for sandwich panel structures and composite bonding.
Betamate is an epoxy adhesive for metal bonding are very cost effective and provide special mechanical and corrosion resistant properties.
MMA adhesives don't need extensive surface preparation and offer a perfect balance between working and curing times.
