A linerless, self-fusing elastomeric tape having an adhesive layer and a mesh that serves as a release liner in storage and further is a part of said tape in a sealing function. The adhesive layer includes blends of a first halogenated rubber component and a second non-halogenated modified rubber component. In application, the stretched mesh includes a plurality of openings such that when the adhesive layer and mesh is stretched, the mesh allows cross-linking between the layers of the adhesive layer through the plurality of openings allowing the layers to extrude through the openings of the mesh for purposes of bonding.

I claim: 1. A self-fusing tape for protecting or sealing a substrate, said tape comprising: an adhesive layer and a mesh, said adhesive layer comprising a blend of a cross-linkable halogenated rubber component, a non-halogenated modified component, and a cure system, said cure system comprising a combination of phenolic resigns of about 0.5% to about 1.5% of the total mixture blend, said mesh comprising a plurality of openings such that stretching said mesh allows cross-linking between layers of said adhesive layer through said plurality of openings. 2. The tape as recited in claim 1, wherein said adhesive layer further comprising a petroleum product of about 20% to about 30% of the total blend. 3. The tape as recited in claim 2, wherein the petroleum product is polybutene. 4. The tape as recited in claim 1, wherein the halogenated rubber component is of about 10% to about 25% of the total blend. 5. The tape as recited in claim 4, wherein the halogenated rubber component is further blend with a wetting agent of about 0.5% to about 1.5% of the total blend. 6. The tape as recited in claim 1, further comprising a colorant of about 1% to about 1.5% of the total blend. 7. The tape as recited in claim 6, wherein the colorant is carbon black. 8. The tape as recited in claim 1, further comprising a filler. 9. The tape as recited in claim 8, wherein the filler is about 48% to about 55% of the total blend. 10. The tape as recited in claim 1, wherein the proportion of the halogenated rubber component does not exceed about 30% of the total blend. 11. The tape as recited in claim 1, wherein the proportion of the cure system does not exceed about 2% of the total blend. 12. The tape as recited in claim 1, further comprising a tackifier of about 2% of the total blend. 13. The tape as recited in claim 1, wherein said mesh is constructed of a cloth material. 14. The tape as recited in claim 1, wherein said mesh is constructed of a metal material. 15. The tape as recited in claim 1, wherein said mesh is constructed of a rubber material. 16. The tape as recited in claim 1, wherein the halogenated rubber component is selected from the group consisting of butyl rubber, halogenated butyl rubber, isobutylene homopolymer, ethylene/propylene, diene terpolymers, ethylene/propylene copolymers, polybutadiene, polyisoprene, halogenated isoolefin/paralkylstyrene copolymer, natural rubber and combination mixtures thereof. 17. A process of affixing to a substrate a tape having insufficient tack to self-bond in its relaxed state and comprising a mixture of: (a) from about 10% to about 25% of the total blend mixture of a cross-linkable halogenated rubber component, (b) from about 0.5% to about 1.5% of the total blend mixture of a cure system comprising a combination of phenolic resigns, (c) from about 20% to about 30% of the total blend mixture of a petroleum product, (d) from about 1% to about 1.5% of the total blend mixture of colorant, (e) from about 48% to about 55% of the total blend mixture of a filler, said tape further including a mesh comprising a plurality of openings, wherein said tape is subjected to a stretching elongation immediately prior to contact with the substrate, wherein the elongated tape is applied to the substrate in a wrapping operating, and wherein said stretched mesh allows cross-linking between the overlapping layers through said plurality of openings such that said overlapping layers of said tape self-bond to each other. 18. The process of claim 17, wherein the colorant is carbon black. 19. The process as recited in claim 17, wherein the petroleum product is polybutene. 20. The process as recited in claim 17, further comprising a tackifier of about 2% of the total blend mixture.
