Abstract: Metal-polymer composite articles, e.g., knobs, nuts, trimmings or ornaments, automotive components including grilles, headlamp bezels and surrounds, wheel covers, trim, hubs and like parts, having silvery hued metal surfaces comprise surface plating composed essentially of an alloy of tin and Group VIII metal that is durably joined to a supportive solid body containing a directly electroplateable polymeric material, e.g., a composition wherein carbon black and sulfur are combined with a polymer. Polyvinyls, polyolefins, polystyrenes, elastomers, polyamides and polyesters are among the suitable polymers. A durably adherent layer of nickel-based metal is disposed between the body and the surface plating. Durability of the surface plating includes resistance to thermal cycling and to salt spray corrosion.

Abstract: A method for adhering rubber to reinforcing materials which comprises embedding a textile fiber or metal reinforcing material in a vulcanizable rubber composition comprising rubber, a vulcanizing agent and an imidazolidinone and vulcanizing said composition.

Abstract: Process for the direct joining of rubber to metal surfaces by vulcanization using a rubber mixture containing the additives common for sulfur vulcanization wherein either the rubber mixture contains additionally tellurium, tellurium alloys and/or tellurium compounds as bonding aid, or that tellurium, tellurium alloy and/or tellurium compound is applied on the metal surface before vulcanizing.

Abstract: A composite expanded sheet reinforcing material especially useful as a stiffening, vibration and sound dampening, reinforcing laminate, and methods of manufacturing such sheet reinforcing material and of reinforcing articles therewith are disclosed. Formable sheet material having a layer of a foamable adhesive laminated thereon is passed through an expanding apparatus which forms rows of spaced, longitudinally staggered slits through the laminated sheet to form a series of elongated strands integrally joined at their ends by a series of joints or bonds. The slit material is expanded in a direction transverse to the longitudinal direction of the slits, causing the adhesive-coated surfaces of the strands and joints to be inclined at an acute angle to the principal plane of the formed reinforcing sheet.

Abstract: A steel wire element useful in the reinforcement of rubber compositions in which the steel wire is provided with an adhesive coating comprising a brass alloy containing 58% to 75% copper, and cobalt in an amount sufficient in use to improve the adhesion between the coated steel wire and the rubber composition. Preferably the brass alloy contains 2% to 4% of cobalt. Applications include coated steel cords for use in vehicle tires and conveyor belts and hoses.

Abstract: A ferrous wire having a homogeneous coating deposited on the wire, with the homogeneous coating comprised of between about 0.3-5.0% by weight of nickel, 60-75% by weight of copper and 40-25% by weight of zinc. The homogeneous coating comprises between about 0.3-16.0 grams of coating per kilogram of ferrous wire and coating. The coated ferrous wire is adapted to provide increased and superior precured humidity aged adhesion and postcured steam-aged adhesion to rubber based products such as tires, hose and belts.

Abstract: The adhesion of an elastomer such as rubber to a metal surface is improved by coating the metal surface first with an alloy containing cobalt and copper, applying the elastomer to the coated metal surface and vulcanizing the elastomer.

Abstract: The bond strength of composite articles of rubber adhered to ferrous metal substrates through an adhesive is substantially improved at ambient and elevated temperatures by depositing a specified amount of a layer of copper on said ferrous metal substrate, applying an adhesive thereover comprising an interpolymer containing about 50 to about 99% by weight of a conjugated diene, about 1-45% by weight of a heterocyclic base and 0 to about 40% by weight of at least one additional copolymerizable monomer, thereafter contacting said adhesive with the rubbber to be bonded and bonding by heat and pressure.

Abstract: An improvement in a process for making a rubber adherable wire, wherein a steel wire is plated with brass and then drawn through dies to reach the desired diameter, comprises coating the brass plated wire with 5.times.10.sup.-5 to 50.times.10.sup.-5 milligrams of zinc per square millimeter of coating surface prior to drawing. The product made by the process is useful for reinforcing rubber articles such as tires.

Abstract: A rubber composition containing reinforcing pigment some of which is preferably silica pigment, sulfur, a vulcanization accelerator, litharge, and a cobalt salt, when coated on brass plated steel cords and vulcanized, adheres tenaciously and permanently to the cords, without the erratic adhesion previously obtained or loss of adhesion in humid atmospheres. A further improvement in adhesion is obtained by including a resorcinol resin in the composition.

Abstract: Certain polyolefin-based compositions are readily electroplatable and possess particularly desirable combinations of characteristics. These are blends of specified proportions and types of polypropylene, low polarity rubber, highly conductive carbon black, polyethylene and optional mineral additives. The compositions permit direct electroplating to give highly decorative, adherent, plated surfaces.
