I’ve used the Dyneema repair tape available from RipStopByTheRoll and Dutchwear, depending on who has availability. It is the same product from either. Not only is this tape strong enough, and the seal permanent enough to repair rips and holes in Dyneema fabric, it is also used to make the seams on dry bags from several manufacturers, and in the dry bag kits from RipStop. I don’t know what the adheisive is but suspect it is the 3M LSE used in various widths of Pressure Sensitive Tape, also used by manufacturers to construct tent.
I was initially skeptical of the PST? I doubted its ability to hold under strain. I was wrong. That stuff is amazing. I’ve built test swatches both of just two pieces of fabric bound together and of guy outs with line locks on DCF fabric. The bond is virtually indestructable.
3M advises that the bond may be broken by stress that pulls the fabrics in opposite directions, imagine peeling packing tape off a box. And that is a fair warning. That one limitation is easily overcome with smart construction, using more than one direction of bond to overcome the weakness. In fact, I use the DCF repair tape specifically for a that because it is so easy to apply, vs. putting down a strip of double sided tape then cutting and applying a strip of DCF over that.
No downside to that tape that I can see. If you are worried about thickness, as on a floor, just use two or more layers of the tape until you feel good. The 3M adhesive can be used to “layer cake” DCF exceptionally well.
Be advised though that for field repair, the tape does need to be applied on a flat surface and must have good pressure applied to activate the adhesive. It adheres instantly, but does improve adhearance with time and a bit of low heat, never over 130F.
Hope that helps!
