My bonding area is very small but I really need high strength. What types of adhesives should I use?

There are several types of structural adhesives that can provide very high strength, including at elevated temperatures. In general, epoxy adhesives will be best for bare metal bonding and bonding thermosets and thermoset composites; and acrylic adhesives are best for thermoplastic bonding.

Epoxies will also generally provide better solvent resistance; whereas acrylics will cure more quickly.

Please see our white paper on Choosing and Using a Structural Adhesive for more discussion about the different adhesive properties.
