QuikDisc VHB – Strong Disc Rare Earth Neodymium Magnets with 3M VHB Foam Adhesive (4920 Very High Bond Acrylic Foam Adhesive), N35 20mm dia x 2mm 4pcs/pack

QuikDisc VHB:
When Neodymium Magnets extraordinary power is paired with 3M Very High Bond (VHB) Acrylic Closed Cell Foam Adhesive, the result is…

Extraordinary Convenience.

Titan Magnetics latest QuikDisc VHB Neodymium Magnets sticks well to most clean, hard and smooth surfaces like Glass, Ceramic Tiles, Aluminum, Wood, Stainless Steel and even painted Concrete Walls.

The last surface, Concrete Wall is a challenge for normal adhesive due to slight uneven surface that greatly reduces the contact with pressure sensitive adhesive. The 3M VHB Foam adhesive with a 0.4mm thickness transverse the uneven gaps to form a mould that allows greater contact area with concrete surface when firm pressure is applied. Furthermore, 3M 4290 is a closed cell acrylic foam that is elastic and doesn’t tear easily compared to normal foam adhesive.

QuikDisc medium sized disc Rare Earth Neodymium Magnets with 3M VHB (Very High Bond) 4920 Adhesive is approximately the size of a Singapore 20 cents coin.
(iconic third series 20 cents coin is 21mm dia. x 1.7mm )

3M VHB 4290 acrylic foam thickness of 0.4mm allows the neodymium magnet to adhere relatively well on smooth painted concrete walls.

Magnet With 3M VHB Adhesive 4920

Neodymium Magnets 3M Adhesive Foam

For standard magnets without adhesive, polarity doesn’t really matters as you can always flip a magnet around if it repel.
But on these disc neodymium magnets where 1 side is adhesive, it makes a great difference because if you stick a North facing on the wall and also a North facing on an object, eg. a remote controller, you will not be able to attach the remote control to the wall as North and North will repel.

Facing pairs magnets: 2pcs adhesive on North, 2pcs adhesive on South means you can use these magnets in more ways.
– Magnet to Magnet (Use facing pairs on opposite surfaces)
– Magnet to Metal objects or surfaces (Polarity does not matter)

Magnets with 3M Foam Adhesive suitable for concrete wall

Concrete walls with slight uneven surface pose a great challenge to standard adhesive, the 0.4mm foam thickness of 3M VHB 4920 allows the adhesive surface to “mould” in to the peaks and valleys of concrete surface for maximum grip.

This acrylic foam base adhesive also reduce vibration and shock when used on vehicles or areas with movement, hence reduced the chance of objects that are magnetically attached from dropping due to sudden shock.

3M VHB 4290 Acrylic Foam 0.4mm Adhesive works on most smooth and hard surfaces:
– Smooth Painted Concrete
– Stainless Steel, Aluminium, Painted Steel, Powder Coated Steel
– Smooth Wood
– Ceramic Tiles
– Glass

3M VHB 4290 Adhesive Instructions for strong, permanent adhesion:
• Clean surface with alcohol swap
• Dry surface with clean cloth
• Remove 3M VHB wax paper (Avoid touching the adhesive surface.)
• Apply firm pressure for 30 seconds to ensure maximum adhesion
• Leave to cure for at least 1hr before use. (Best to leave it for 24 hours for best results, to allow VHB compound to seep into cavity)
