Abstract

Liquid resins and plastisols can be made to assume and hold desired shapes, or to bridge gaps, not attainable with the present commercially available filled liquid resins or plastic puttys by employing a '"'"''"'"''"'"''"'"'filler'"'"''"'"''"'"''"'"' material, which has magnetic property.

Claims

2. A method according to claim 1 in which the resin is a liquid epoxy resin.

3. A method according to claim 2 in which the particles of magnetic filler are no more than 74 microns in size.

4. A method according to claim 5 in which the ceramic magnetic filler is selected from magnetic iron oxide, barium ferrite, and strontium ferrite.

5. The method as recited in claim 1 wherein said magnetic filler comprises magnetic ceramic magnets.
