Seven Things to Consider When Determining Bonding Requirements


When considering bonding and sealant options, answering a few simple questions can help guide you to the right solution.

1.  What Are You Joining Together?

Is it a sub-assembly or a finished part, and is disassembly a consideration?  Also, does it require bonding (e.g. adhesive) or joint filling (e.g. sealant)?

2. Substrates?

What substrates are you connecting, and are those materials rigid, flexible, smooth, rough, non-porous, or treated?  And if the substrate turns out to be treated, with what?  Finally, does your adhesive need to be stronger than the substrate itself?

3. Design Joint?

Is your design joint going to be under high stress, dynamic load, or static load?

4. Application?

Will you be applying your adhesive or sealant manually, or assisted by either a machine and/or a fully automated process?

5. Curing?

How do you intend to cure your adhesive or sealant?  For example, will it be by heat, or moisture, or UV light, or electron beam light, etc.?  Also, what is the service temperature range that will be needed when applying your adhesive or sealant (whether continuously or intermittent)?

6. Resistance?

Is there anything your adhesive or sealant needs to resist, like moisture, or immersion, or weathering, or sunlight, and more?

7. Standards?

And finally, do you need to comply with standards like UL, US FDA, etc.?
