The magnetic soft white board USES NS adhesive as its back and nanometer lapping and pressing technology, which can ensure the uniform distribution of iron particles on the back and strong adsorption on the magnetic bottom. It is composed of NS ferric particles on the back, rubber magnetic bottom and 3M magnetic backing. It adheres to the surface of phototear and has a good persistence, which can be maintained for more than 5 years. Magnetic adsorption structure, no nails, no glue, used in children's household whiteboard. Before the operation, the wall needs to be cleaned and a layer of magnetic bottom installed. The white board can be adsorbed on the magnetic bottom, which can reduce the damage to the wall, and the installation and replacement is more convenient.
