Adhesives at the design stage: Streamlining the path to production

Author : Simon Gibbs, Intertronics

04 April 2022

Adhesives are often treated as the final piece of the jigsaw puzzle. But by the end of the design stage, it may be difficult to find an adhesive that meets all the criteria, meaning the design must be amended, or even started again. Here, Simon Gibbs, Technical Sales Executive at Intertronics, explains the benefits of considering adhesives early in a project.

Though it may initially seem like a simple task, adhesive bonding is a vital and challenging part of product design. Every application is different and establishing what works best for your application involves detailed discussions and testing. For design engineers without specialist adhesives experience, consulting with an adhesives supplier early on will avoid complications down the line, saving time and money. 

In many cases, manufacturers contact adhesives providers once most of the design work is done – once they have finalised and assessed bondline design, substrate selection, environmental resistance, and more. The difficulty with this approach is, with much of the design finalised, there will be a particular set of requirements the adhesive needs to meet – a very specific gap in the jigsaw for the adhesive to fill. There may not be an adhesive that meets the criteria without major compromise, or a suitable adhesive may not be available in the specified packaging or quantities. If this is the case, the design may need to be changed, delaying the project and increasing the costs.

It is much easier to make changes to the design earlier, while the process is fluid.
