Dyneema X to Cuben 1.5 via Loctite?

Hi Kaleb-

I assume you are talking about Loctite Hysol? If so, it should bond those together although I haven't tried it. I do know Seamgrip will bond those together which is also a urethane adhesive. Someone will probably chime in that has done it.

The surface texture of the fabric will hold a lot of glue, and the seam will be very hard and stiff. I'd be surprised if even a heavy industrial sewing machine could sew through that.

Why are you gluing then sewing?

I was speaking OG Loctite hysol, which I heard was flexible. This is for a pack I'm working on.

Kaleb, I assumed that you meant Hysol. I've used Loctite Hysol U09-LV and U09-FL for cuben/cuben bonding, cuben/fabric bonding, fabric/fabric bonding, and hard plastic/fabric bonding. If you have some hysol, I'd recommend that you test the flexibility by bonding a small scrap of Dyneema X to a small scrap of cuben. You'll have a rigid little wafer when it cures.

You may be able to sew through it if you have a herculean sewing machine, but fabric/fabric and fabric/cuben hysol seams break the needles and challenge the motor on my sewing machine. It worked once for me, when I bonded TiGoat's 0.7 oz/yard, 8 denier nylon to cuben and clamped it as tightly as possible to force out most of the glue.

This adhesive is only flexible when the layer is very thin.

Thanks, I don't have any but wasn't sure if I should get some to try to make my seams stronger on my current pack project. I think I will just sew it and seam seal the inside, thanks.
