Starbond Super Glue for Magnets (2oz)
Starbond Thick CA Glue: The Ultimate Magnet Adhesive
Secure your neodymium magnets with professional-grade precision. Starbond Thick CA (Gap Filler) is the go-to adhesive for hobbyists and engineers who need a reliable, high-strength bond that won't migrate during application.
Why it’s Perfect for Magnets
- No-Drip Gap Filling: Neodymium magnets often require a slight "pocket" or recessed hole. The high viscosity of glue fills those microscopic voids between the magnet and the substrate, ensuring 100% surface contact.
- Stay-Put Formula: Unlike thin glues that run onto the face of the magnet, this "Thick" formula stays exactly where you place it - even on vertical surfaces or inside deep bore holes.
- Extended Positioning Time: Don't get stuck in the wrong spot. With a curing time of up to two minutes (depending on the material), you have plenty of time to perfectly align your magnetic poles before the bond sets.

How to Securely Glue Neodymium Magnets with Starbond CA Superglue
Gluing high-strength magnets requires a specific approach to prevent the magnet from "jumping" or peeling away. Follow these steps for a permanent bond:
- Surface Prep (Crucial): Clean the magnet and the bonding surface with isopropyl alcohol.
- Scuff the Surface: Use fine-grit sandpaper (300-400 grit) to lightly scuff the side of the magnet you are gluing. This "mechanical tooth" gives the thick CA glue significantly more surface area to grip.
- Apply to the Recess: Instead of applying glue to the magnet, apply a small bead of glue into the hole or surface where the magnet will sit. This prevents the glue from being pushed up onto the top face of the magnet during insertion.
- Check Polarity: Before the magnet touches the glue, double-check your poles! Once the glue sets, removing a strong magnet usually requires destroying the housing.
- Press and Hold: Firmly press the magnet into place. Because this glue is a "thick" formula, it will fill any gaps between the magnet and the wall of the hole. Hold for 30–60 seconds.
- Full Cure: While the bond feels "set" quickly, allow 24 hours for a full chemical cure before subjecting the magnet to high-impact "snapping" forces.
