Adhesives for composites: BETAFORCE for multi-material light vehicles.
For high-performance bonding in multi-material lightweight vehicles, DuPont’s BETAFORCE composite adhesive enables significant weight reduction, maintenance of acoustic performance flexibility, and achievement of processing performance and sustainability goals.
BETAFORCE: The ideal choice for various applications
BETAFORCE is perfect for joining carbon fiber and fiberglass composites and other dissimilar materials in a variety of projects involving lightweight materials, including modular assemblies. This composite adhesive can be used to join coated metals such as steel to aluminum, carbon fiber panels to steel or aluminum, and sheet molding compounds (SMC) to aluminum.
Composite adhesives: in the automotive world.
Composites are gaining ground in automotive manufacturing because of their weight-saving potential, but they remain difficult to bond with other materials. Composite adhesives offer a reliablealternative to traditional mechanical and thermal processes that cannot be applied to these lightweight materials. Advanced bonding solutions, such as Dupont’s BETAFORCE composite adhesives, provide a continuous bond line and cohesively join surfaces. Recent formulations of BETAFORCE offer a cycle time of about one minute and are currently used for mass production. Open times can be adjusted to suit specific mounting requirements in the implant, such as faster curing time by infrared treatment, and initial adhesion does not require additional fastening tools.
