Dissimilar Material Bonding

The SCIGRIP range of MMAs excel when joining dissimilar materials, combining metals, composites and thermoplastics within a single assembly, which is widely used in the automotive, transportation, construction, renewable energy and marine industries where multi-material design and structural performance are critical.

Why Dissimilar Material Bonding?

One of the most significant challenges in modern manufacturing is the need to join different materials together within a single structure.

As industries move towards lighter, stronger and more sustainable designs, assemblies increasingly combine metals, composites and plastics in ways that traditional joining methods such as welding, riveting or mechanical fastening simply cannot accommodate.

SCIGRIP MMAs provide a reliable, high-strength solution that bonds across material boundaries, distributes stress evenly and protects against galvanic corrosion at the joint interface.

Benefits of using SCIGRIP MMAs on Dissimilar Materials

True multi-material bonding

Join metals, composites and thermoplastics within the same assembly without the need for multiple adhesive systems or mechanical fasteners.

Galvanic corrosion prevention

The adhesive acts as an insulating barrier between dissimilar metals and materials, preventing the electrochemical reactions that cause corrosion at the joint.

Improved aesthetics

Create clean, seamless joints across different material surfaces with no visible fixings, heat distortion or surface damage.

Durability

Outstanding fatigue, impact and environmental resistance ensures long-term bond integrity even where different materials expand and contract at different rates.

Design freedom

Accommodate the dimensional and thermal differences between dissimilar materials with flexible, high-performance bond lines that absorb stress and movement across the assembly.
