Just found your post. I’m also planning to build a shelter that will require to attach Cuben to “no-see-em” netting fabric and a zipper. My research online reveals that the standard procedure to attach zippers and or “no-see-em” netting to cuben is by sewing. You will need to reinforce the cuben part (i.e have 2 or more layers of cuben) prior to sewing and seal the stitches if need a waterproof seam.
Dan Durston, an experienced MYOG member of these forums, posted on one of his projects that he had good results bonding an Uretek zippers (waterproof zipper) to cuben fabric using Loctite’s Hysol adhesive). At the end he went with the standard stitching method just to be safe, but that doesn’t mean that bonding option is out.
Since I don’t have a sewing machine and I would prefer not to bother friends that do, I have experimented with bonding scrap pieces of fabric with good results, at least on “my lab”.
Basically I used 3M’s 9485PC adhesive transfer tape and “sandwiched” the fabric part of the zipper (tape?) with Cuben. The bond seems pretty strong and I have not been able to break it by pulling really hard. The same applies to “No-see-em” netting. Here is a diagram of my “sandwich”
I’m not sure how the bond will do on the long term, and as I reply to your message, I was hoping some other members on this forum can chime in, if they have any input on this matter. I'm almost ready to start the building of my shelter.
