ABSTRACT:
A coaxial cable is provided with a specially prepared precoat layer that facilitates removal of the precoat layer when the end of the cable is cored in preparation for receiving a connector. The cable includes an inner conductor; a foam polyolefin dielectric layer surrounding the inner conductor; an outer conductor surrounding said dielectric layer; and a precoat layer disposed between the inner conductor and the dielectric layer. The precoat layer forms a first bond interface with the inner conductor and a second bond interface with the dielectric layer, wherein the ratio of the axial shear adhesion force of the first (“A”) bond to the axial shear adhesive force of the second (“B”) bond is less than 1, and wherein the ratio of the axial shear adhesion force of the “A” bond formed by the precoat layer between the inner conductor to the dielectric layer to the rotational shear adhesion force of the bond is 5 or greater.
