Silicone discs Ø 20 mm

self-adhesive, 36 per set
promptly deliverable


These self-adhesive silicone discs increase the friction between the disc magnet and base and therefore raise the magnet's weight carrying capacity in shear force. They also protect sensitive surfaces from scratches.
You can either glue them directly on the bottom side of a round magnet or the metal surface to which the magnet will be attached. The strong 3M adhesive ensures long-term hold.
All details for silicone discs can be found in the main text.

The disc magnet S-20-10-N (20x10 mm) can hold approximately 1,75 kg in shear direction, then the steel plate starts sliding down.
With a self-adhesive silicone disc between magnet and steel plate (invisible because it has the same diameter as the disc and is only 0,5 mm thin) the disc magnet can hold over 5 kg in shear direction; then it starts to slide down.
