Details:

Inner Wrap Three - ply tape double sided adhesive consisting of a stabilised polyethylene backing with plastic butyl on both sides. The consistency of the butyl on the one side should be formulated in such a way that, under tension, it flows on uneven steel surfaces. To facilitate correct application, this butyl is a grey colour. The grey butyl layer of the tape face the steel and this should always be the thicker layer of butyl rubber.
