I'm interested as well, if the fabric is relatively light (<5oz/square yard) and breathable. I'd rather have a breathable fabric that I can stabilize by impregnating the seams with urethane than a non-breathable fabric that differs little from Cuben.
I have a few questions about it, though. Is this DSM's Dyneema, or a Chinese Dyneema-like fiber? I read a paper in a materials science journal that compared these two and found that the Chinese product (used in huge quantities worldwide for ballistic fabrics and fishing line) had very inconsistent properties and often underperformed. If it is DSM's Dyneema, do you know which grade (sk60, sk75, etc.)?
Just for the sake of argument, I don't think DIY lamination with adhesive film or seam welding will work with dyneema fabric. Adhesives bond to dyneema very weakly, and you won't achieve a good laminate with stock adhesive film and household tools.
Seam welding can only join laminated fabrics. It is the film that welds, not the fibers. Most synthetic fabrics used in outdoor gear (nylon, polyester, polypropylene, dyneema, etc.) are at least somewhat oriented. Melting any of these fibers results in loss of orientation, loss of strength, and shrinking. I doubt that one could find a film that has a lower melting temp than UHMWPE and is strong and adherent enough for seam welding.
