BETAMATE Structural Adhesives


Producer:  DuPont
Products:  90
BETAMATE® structural adhesives deliver advanced solutions for bonding similar and dissimilar substrates, closures, and body structures, enabling improved load carrying capabilities, vehicle stiffness, durability, design flexibility, and weight reduction.As an example of what BETAMATE® can help you achieve, this is what happens 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; 0.62 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.
