Two layers of this self amalgamating tape form a flexible dielectric layer that protects your connection against moisture, humidity and corrosion. The tape offers high tensile strength, enabling you to stretch the first layer of tape to form a solid, compressed, watertight seal. Apply the second layer with minimal to no stretch, and your insulation job is complete. Just two layers form a moisture-proof, abrasion-resistant, dielectric seal. Suitable for high and low voltage applications. Smooth filler putty compound available for use under tape when insulating bolted or dimensionally inconsistent splices and terminations.
