When the Going Gets Tough, You Need Structural Adhesives

The future of manufacturing will demand lightweight design, high productivity and economic efficiency – all of which can become a reality with the use of versatile, flexible and reliable structural adhesives.

As the manufacturing and assembly processes industry continues to demand the absolute best in speed, quality, reliability and durability, it comes as no surprise that structural bonding has become a key technology of the 21st century and an essential fitting method in all industrial sectors – especially where different materials have to be bonded together.

Traditional structural joining methods such as riveting, bolting, welding and soldering once dominated this space, but presented a number of detrimental disadvantages to production, safety and bonding capacity.

In cases where mechanical processes such as riveting or bolting were used, the transfer of force was only possible at specific points – creating peak stresses at certain points and increasing the risk of fatigue related fractures. In cases where welding and soldering were used, joining materials that were unable to withstand extreme temperatures would lead to unreliable and unsustainable bonds.

The need for strong structural adhesives

In contrast, the all-round versatility of structural adhesives enable the loads to be more evenly distributed across the entire bonding surface, creating superior bonds.

Similarly, structural adhesives also enable heat-sensitive materials such as aluminum, plastic and very thin components to be securely bonded. As a non-conducting material, cured adhesives also have an insulating effect, thus preventing contact corrosion.

The ability to bond almost all types of metals – both conventional standard steels and stainless steel and aluminum – as well as synthetic and fiber composite materials and glass, plastics or ceramics quickly and securely is one of the reasons why adhesives are now regarded as an established part of many production processes.

The use of structural adhesives offers improved aesthetics compared to mechanical fasteners, increased processing speeds during the design and manufacture process, reduced labour costs, excellent resistance to severe environmental conditions, filling of large gaps between parts, a more cost-effective design and reduced component weights.
