BETAMATE™ structural adhesives

DuPont introduced structural adhesives to the market in 1999 to enable lightweighting and reduce welding and mechanical fasteners while improving vehicle stiffness and crashworthiness, and we are still innovating.

New BETAMATE™ broad bake structural adhesives are a novel solution enabling sustainable manufacturing of next-generation electric vehicles. The lower adhesive curing temperature enables a reduction of the e-coat oven temperatures for more sustainable manufacturing and facilitates novel electric vehicle design enhancing battery integrity and therefore passenger safety.


Here’s an example of what BETAMATE™ crash durable structural adhesives can help you achieve when a mid-size vehicle with 50 meters of BETAMATE™ is operated for one year:

  • 10 kg primary mass reduction
  • 17 kg total weight savings with mass decompounding
  • .62 percent improvement in fuel efficiency
  • 32.6 kg carbon dioxide reduction

BETAMATE™ structural adhesives offer high-performance adhesion to automotive substrates such as steel, aluminum, magnesium, and composites. It replaces welds and mechanical fasteners, reducing fatigue and failure commonly encountered with traditional processes, and substantially increasing manufacturing efficiencies.
