If you need to bond metals, but soldering or welding are not viable options, then metal bonding adhesives could well be the best choice. There are a number of different types which are outlined below.

Epoxy Adhesives

Epoxy adhesives are regarded as the most effective for metal-to-metal bonding. They are able to create a long-lasting and reliable bond and are also able to withstand demanding conditions including inclement weather. These are usually made up of a hardener and a resin and are widely used in the automotive, construction and aerospace industries.

Polyurethane Adhesives

Polyurethane adhesives are simple to use (do not need to be mixed) and also offer unique properties including elongation and flexibility. They are a good option for applications where vibrations or movement are involved. They take around 6-8 hours to cure.

Cyanoacrylate Adhesives

Colloquially known as “super glues”, these adhesives are able to produce rapid bonding. They are used by DIY enthusiasts as well as companies in the electronics and veterinary/medical industries.

Silicone Adhesives

Silicone adhesives offer excellent resistance to heat and are often used in automotive applications as well as for joining small electronic components.

Acrylic Adhesives

Acrylic adhesives are widely used in various industries and DIY applications. They are durable, strong, and resistant to high temperatures, UV radiation, and harsh chemicals.

Methacrylate Adhesives

Often referred to as MMA adhesives, these are a popular choice for bonding metals. They require minimal (if any) surface preparation. These adhesives comprise a resin and a hardener – although many also contain some rubber. They do not require heat to cure and are resistant to shear and impact stress.

Industries and Applications

The ability to bond metals is crucial in numerous industries, including automotive, aerospace, construction, electronics, and manufacturing. They are used for bonding critical aircraft components, joining key architectural elements, and bonding various electronic/microelectronic components.
