ABSTRACT:
The sealant compound of this invention comprises polyurethane resin or its precursor mixed with vapor grown carbon fiber. In the compound, whisker-shaped carbon fibers with high tensile strength intertwine and form lattices. In addition, carbon fibers are anchored in the polyurethane resin. Consequently, the compound of this invention has more tensile strength than the conventional compound containing black carbon. Thus the seal consisting of the compound of this invention has high adhesion and sealing effects.
