QuikDisc VHB – Disc Neodymium Magnets Black Epoxy Water Resistant with 3M VHB Adhesive Grade N35 20mm dia x 2mm 4pcs/pack

Titan Magnetics QuikDisc VHB is a set of disc-shaped neodymium magnets with black epoxy plating and 3M Very High Bond (VHB) adhesive. These magnets are designed to provide a strong and secure bond for various applications. With a diameter of 20mm and a thickness of 2mm, they are compact and versatile. The black epoxy plating not only adds an attractive finish but also provides protection against corrosion and wear. The 3M VHB adhesive ensures a reliable and long-lasting bond, making it suitable for both indoor and outdoor use. These magnets are water-resistant, allowing them to be used in humid environment. With 4 pieces per pack, the QuikDisc VHB is a convenient and practical choice for DIY projects, crafts, and other applications that require a reliable and durable magnetic solution. 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) 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 – Glass3M 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) Specifications: Diameter: 20mm Thickness: 2.4mm (including 3M VHB 4920 Acrylic Foam Adhesive) Weight: appx. 4.9g Grade: N35 Plating: Black Epoxy Magnetisation: Thru 2mm thickness Max.
