    • Novel conformable adhesive tapes consisting essen­tially of: (1) a water-impermeable backing layer from about 1 to 3 mils thick; (2) a flame-retardant, evenly tearable synthetic fibre cloth or scrim; (3) a flame-­retardant adhesive layer, preferably a rubber-based adhesive; and (4) a thin tie coat layer between the backing and the scrim which, when applied as a molten mass, at least partially fills the interstices between the fibres of the scrim so as to provide surface contact with the underlying adhesive layer, the tie coat providing a strong bond at both the tie coat/­backing interface and the tie coat/scrim and adhesive interfaces, thereby providing a laminar product possessing the desired anchorage and structural stability and integrity.
      The tape is particularly useful in wrapping irregular surfaces, e.g. as a wire harness wrap, where conformability is essential to good adhesive contact.

      18 alkyl radical and x = 1, 2 or 3; y = 0 or 1 and z = 4 –x –y; at least one metal compound selected from the group consisting of metal acetylacetonates, metal alkoxides and alkoxy-metal acetylacetonates. A primer of this kind enables effective promotion of adhesion between pressure-sensitive adhesive tapes and hydrophilic surfaces like glass especially, and allows for incorporation of functional fillers.
