Dow Automotive Systems (Schwalbach, Germany) has furnished various automakers with customized adhesive solutions that enable bonding of lightweight materials, including carbon fiber composites. Application areas include compartment solutions for compact electric cars as well as trunk lids. Dow Automotive adhesives have also recently been deployed in the BMW i3 production, thereby realizing a complete carbon fiber body-in-white.

Recent formulations of this adhesive offer a cycle time of around one minute and are currently being used for mass series production. Open time (the amount of time recommended for an adhesive to set before it is contacted with the opposing joint surface) can be adjusted to accommodate specific mounting requirements in the plant, such as a quicker curing time by infrared treatment. Further, the initial adhesion requires no additional fixing tools.
"Dow Automotive Systems is one of the pioneers in automotive bonding with more than 20 years of experience," said Steve Henderson, president Dow Automotive. "Now, this heritage is benefitting our current automotive customers as they increase their use of lightweight materials. Our expertise in the chemical aspects of adhesives as well as our application and process knowledge make us a leading development partner for all lightweight bonding technologies".
Dow Automotive is seeing an increase in requests for composite solutions, not only on the adhesive side but also for its resin portfolio and expects a significant growth here in the coming year.
