Abstract: A metallic substrate and a thermoplastic resinous coating are bonded to one another by a resinous hot melt adhesive. The method of applying the coating to effect the bond includes applying to the metallic substrate a resinous hot melt polyamide adhesive composition which has been found to adhere firmly to the metallic substrate and to form a secure bond with the molten thermoplastic resin extruded onto said hot melt adhesive at high rates of speed.

Abstract: A metallic substrate and an outer thermoplastic resinous coating are bonded to one another by a resinous polyamide hot melt adhesive prepared by condensation of an unpolymerized amide-forming dicarboxylic-containing compound or polymeric fatty acid with a diamine of the formula ##STR1## wherein each of R.sup.4, R.sup.5, R.sup.6 and R.sup.7 is a hydrogen atom or an alkyl radical; X is a nitrogen atom or a carbon atom bearing a single hydrogen substituent and n is an integer of from 1 to 6 inclusive. The adhesive is first applied to the metal substrate with sequential deposition of the thermoplastic resinous outer coating.

Abstract: Fence fabric formed of a multiplicity of entwining electrically conductive metal wire cores each coated with a heat disintegrable electrical insulation is rendered susceptible to grounding by disposing each of said metal cores in contact with at least one electrically conductive ground element. To produce this product, one or more of the foregoing conductive elements is placed in permanent contact with each coated wire of the fence fabric and sufficient current passed through said conductive element to disintegrate the insulation coating and provide an electrically conductive path between the metal core of each of said wires and said electrical conductor.

Abstract: A metallic substrate, such illustratively as wire, to which is bonded by means of a resinous hot melt adhesive and in a continuous operation a thermoplastic resinous coating. The method of making the coated metallic substrate comprises applying a resinous hot melt adhesive about the metallic substrate and thereafter extruding a molten thermoplastic resin onto the deposited adhesive at high rates of speed.
