Abstract
One embodiment includes a magnetic particle-containing adhesive an adhesive including a polymer resin having a softening temperature; and magnetic particles dispersed within the polymer resin.
Claims29
A product comprising:
- an adhesive comprising a polymer resin having a softening temperature;
- and
- magnetic particles dispersed within the polymer resin.
A method comprising:
- providing an adhesive comprising a polymer resin having a softening temperature;
- providing magnetic particles;
- mixing said magnetic particles and said adhesive material to form a dispersion of said magnetic particles in said adhesive;
- and,
- cooling said adhesive to form a composite material comprising said magnetic particle containing adhesive.

A method of bonding surfaces comprising:
- providing a first bonding surface;
- providing a magnetic particle containing adhesive in powdered form dispersed on said bonding surface, said magnetic particle containing adhesive comprising:
- an adhesive comprising a polymer resin having a softening temperature;
- and
- magnetic particles dispersed within the polymer resin;
- providing one or more magnets proximate said bonding surface to accumulate said hot melt adhesive in predetermined locations on said bonding surface;
- heating said hot melt adhesive to a softening temperature;
- contacting a second bonding surface with the softened hot melt adhesive;
- and,
- cooling said softened hot melt adhesive while in contact with said second bonding surface to form a bond bridging said first and second bonding surfaces.
