Bonding & Joining in Automotive Interiors

CONNECT WITH A 3M EXPERT

New bonds for better interiors

Vehicle interiors are evolving to accommodate the transition to autonomous driving and increased shared mobility, requiring -- more durable, replaceable materials, storage compartments, instrument panels, and interactive infotainment centers. Bonding dissimilar materials and the desire for optimizing package space are among the challenges. Tried and true bonding methods such as bolts, rivets and spot welding may not be optimal in these modern interior design challenges.

3M can help, with our extensive experience in the automotive bonding and joining. The result is an ever-growing range of bonding solutions that can also streamline assembly and production. Learn more below.
