ABSTRACT:
A hot melt magnetic sealant that exhibits improved adhesion to oil covered galvanized ferrometallic substrates and to epoxy electrodeposition coated ferrometallic substrates is disclosed. The sealant comprises magnetic filler particles, a hydrocarbon resin, a tackifier resin, a plasticizer, an epoxy resin and an epoxy curing agent. A method for making a hot melt sealant tape comprising mixing a formulation of magnetizable particles, a hydrocarbon resin, a tackifier resin, a plasticizer, an epoxy resin and an epoxy curing agent, extruding the mixture to form a tape and exposing the tape to an electromagnetic field is also disclosed. Methods for using the magnetic sealant tape to seal a joint between ferrometallic members having oil covered galvanized surfaces or epoxy electrodeposition coated ferrometallic members comprising disposing the tape to cover the joint and heating the tape are also disclosed.
