Ideal for closure applications and really popular in the print finishing industry these thin neodymium self-adhesive magnets can attract when positioned with layers of card in between. If your project requires magnet-to-magnet attraction, use North polarity with South polarity magnet to avoid repelling. These high-performance Neodymium magnets utilise a firm acrylic pressure-sensitive adhesive that substantially increases in bond strength with natural aging. While the initial touch bond strength is enough to support the weight of the magnet, to ensure the adhesive can withstand the magnets pull strength we recommend allowing between 24 to 32 hours for the adhesive to fully cure. SPECIFICATIONS. 9.5mm x 0.75mm. 0.35kg pull.
