Is produced in the form of a triangular cross section with a colored guide line running along the peak of the triangle. The guide line facilitates winding of the tape so minimum overlapping is obtained while maximum physical and electrical properties are retained. The tape is interleaved with a quick release film. It is self-bonding and self-fusing. After curing at room temperature for 24 hours, the tape forms an inseparable silicone layer that must be cut for removal.
