Epoxy magnets (12)
Epoxy magnets are neodymium magnets with an extra layer of epoxy over the standard coating. This layer makes them more resistant to moisture, sweat and corrosion, and often gives them a black colour. This makes them suitable for damp areas, outdoor applications and places where the magnet remains visible.
Our range of epoxy magnets
- Disc magnets: Ø5 to Ø10 mm
- Block magnets: from 30 x 10 mm to 80 x 20 mm, also available as a value set
- Rod and cylinder magnets: Ø3 x 6 mm black and Ø25 x 15 mm N42H
- Ball magnets: Ø5 mm black
- Ring magnets: Ø20 mm with drilled/countersunk hole, in north-pole and south-pole variants
Epoxy or NiCuNi?
| NiCuNi (standard) | Epoxy | |
|---|---|---|
| Appearance | Shiny silver | Usually black |
| Moisture and corrosion | Suitable for dry indoor use | More resistant to moisture and outdoor use |
| Wear resistance | Hard layer | Softer layer, can be damaged by impacts |
The epoxy layer is slightly thicker than NiCuNi and therefore increases the distance to the steel by a fraction, which slightly reduces the holding force. Not sure? Read Which coating or finish should you choose? or view the application epoxy coated magnets in steel doors.
Frequently asked questions
Can I use epoxy magnets outdoors?
Yes, in sheltered areas and damp spaces such as a bathroom, camper or caravan they will last much longer than magnets with only NiCuNi. If they are constantly exposed to rain or water, seal them extra or choose a plastic coated or rubber coated version.
Are epoxy magnets waterproof?
They are more resistant to moisture than magnets with only NiCuNi, but they are not indestructible. If the coating is damaged, the magnet may start to rust there.
Are epoxy magnets weaker?
Slightly: the thicker layer provides a fraction more distance to the steel. In practice you will hardly notice this; the holding force is stated for every product.
How do I glue an epoxy magnet?
Use a two-component adhesive, such as UHU Plus epoxy adhesive, on a clean and grease-free surface.
What does the H in N42H mean?
The letter H stands for a higher maximum operating temperature than standard neodymium magnets.
Do you supply epoxy magnets to builders of campers, boats or steel doors?
Yes. Builders order them on account with a purchase order, with volume discounts for larger quantities. If you use them in every build, we reserve stock for a fixed annual intake. Business ordering.
When will my order be shipped?
Ordered and paid for on working days before 16:00, it will be shipped the same working day if in stock. Free shipping within the Netherlands from €45. Consumers have a 30-day cooling-off period.
