The bestseller among the self-adhesive magnetic tapes! This 20 mm wide self-adhesive magnetic tape is made to attach non-magnetic objects to metal surfaces. It consists of strontium ferrite and flexible plastic. On one side it is coated with an adhesive. The adhesive force is 102 g/cm2. The longer the magnetic tape the higher the adhesive force. For heavy objects, we recommend a large enough magnetic tape. Self-adhesive magnetic tapes need to be placed, pressed and dried on suitable surfaces. Otherwise, air may be trapped and the tapes may come undone.
