Does anyone know of adhesives that would be able to stick velcro to nylon permanently and survive washings, stuffings and general trail abuse?
Thanks

McNett Seam Grip is your best option.

I haven't had any joy from any adhesives.
Cheers
Jun 16, 2008 at 7:26 am #1438561Be sure to find a nylon based hook and loop product…that will make the bonding process significantly easier. Also, you'll need to do some heavy cleaning of the two faces you're attempting to bond with acetone or another industrial solvent to remove any and all DWR and other coatings.

Jun 23, 2008 at 10:04 am #1439655I make a little bit of gear on the side, and I've had good luck with McNett products, both Seam Grip and Aqua Seal. Before that was the tried and true Barge cement. All three will dry out to some degree if washed frequently, especially in a machine. But with careful hand-washing you shouldn't have any major problems.
The trick I've found is to apply it to both surfaces, let it set up, then bond it with pressure. You might have to experiment a bit with your adhesive to get the optimum results. Depending on temp/humidity, you may be looking at 30-45 minutes or more.
Surface prep is also huge, like others have suggested. I will use a rapid evaporating cleaner, like lacquer thinner, to clean and slightly soften the base material. Rubbing it in lightly with scotch brite will give the material more "tooth" to bond with.
