BETAFORCE composite bonding adhesives for high-performance bonding in lightweight multi-material vehicles. BETAFORCE adhesives enable significant weight reduction, better corrosion protection and improved acoustic performance.
This composite bonding adhesive is an ideal choice for joining carbon fibre, glass fibre composites and other dissimilar materials such as aluminium, steel and SMC to name but a few.
Composites are gaining traction in automotive production, due to their weight saving potential. Dow Automotive adhesives offer a reliable, alternative joining solution to traditional mechanical and thermal processes, which cannot be applied to these lightweight materials.
