Is Special Glue Needed for Magnet Insertion?

Magnet Embedding During Resin Curing

No separate glue is required when embedding magnets in resin. If you place the magnet into the curing resin, the resin itself envelopes and secures the magnet as it hardens, providing a strong hold within the finished item.

• Insert the magnet at the right moment, typically when the resin is partially cured but still soft enough to allow placement without sinking or movement.
• Ensure the magnet is clean and dry to aid secure encapsulation.

This approach avoids issues with adhesives reacting to the resin or discolouring clear castings.

Best Practice Tips for Successful Magnet Casting

For a neat, professional result, use a suitable mould such as the Cabochon-15 Silicone Mould. Place your magnet gently into the mould at the optimal stage to ensure it remains suspended and does not drift. Choose a resin that matches your project’s requirements; for example, the UV Resin Kit is ideal for small, festive pieces, while “Liquidissima” offers more working time for intricate designs.

When This Matters

If your design has a particularly large or heavy magnet, or if you need to attach a magnet to a fully cured resin piece, separate adhesives such as strong epoxy glues may be needed. For typical small crafting magnets, embedding during the pour is more than sufficient.
