Adhesives with high magnetic properties. Constructed from polymeric matrix incorporating magnetic particles. Used to paste banners, banners and notes on metal surfaces. The presence of the adhesive on one side, enables the adhesion of paper, banners, banners or information, while the other side of the adhesive, with magnetic properties, enables temporary fixation on metal surfaces. Easily fixable on any metal surface. Protects the metal from paint removal and damage, due to the lack of permanent adhesive.
