Abstract
A member for use in undersea applications comprising a plurality of conduits assembled into a bundle; the bundle being wrapped with a pressure-sensitive tape comprising a backing, a layer of corrosion-resistant yarns on one surface of the backing, and pressure-sensitive adhesive layer that coats the corrosion-resistant yarns and binds them to the backing.
Claims20
A tape comprising a polymeric film backing;
- a layer of corrosion-resistant fiber directly adjacent one surface of the polymeric film backing;
- a first pressure sensitive adhesive layer bonding the corrosion-resistant fiber directly to the backing;
- and a second pressure sensitive adhesive layer directly adjacent the first pressure sensitive adhesive layer bonding the corrosion-resistant fiber directly to the polymeric film backing;
- wherein the first pressure sensitive adhesive layer and the second pressure sensitive adhesive layer comprise the same adhesive.
