This is one of the most frequently asked questions we encounter.

In most cases the application will dictate what adhesive you use, however the wrong choice of adhesive may result in the magnet being pulled from its bonded surface. This is especially true of Neodymium magnets due to their greater strength. Using an adhesive like Super Glue which dries hard and without any flexibility can add to this problem.

We recommend the three adhesive types below for use with magnets:

Silicone: Often used for larger magnets, Silicone is a simple and cost effective solution when fixing magnets in place.

Epoxy Resin: This is the most commonly used adhesive as it dries relatively quickly and retains flexibility.

Cyanoacrylate (CA): Similar to epoxy glues, CA requires an initiator to activate and can be applied to metal, plastics & glass. We have tested Bondmasters F246/Initator 5 CA which has superior shear strength and excellent resistance to both peel and fatigue.

The coating of the magnet is also a key consideration. Plastic coated magnets provide good adherence for most forms of adhesive. Zinc coated magnets and epoxy coated magnets are also highly compatible with most adhesives.

We advise customers to review the information provided by the adhesive supplier to ensure it is compatible with magnets.
