Tacky smooth-on
« on: May 01, 2017, 08:39:37 am »
Abandoning Unibond because of issues and I bought some smooth-on to try. A couple of days ago I glued on some nock overlays with it. I mixed equal parts by weight for the glue-up. What squeezed out is as hard as a rock but still feels a little tacky to the touch. Is this normal? I put the bow blank in my drying box at 100 degrees overnight but the excess glue still has a bit of tackiness to it.

I'll be watching this thread Eric... I have lots of bamboo and osage to glue and was about to buy some unibond, since it seems to be the go-to glue these days... it stinks that we can't get urac any more...

It seems like it's more likely to be amine blush if the squeeze out itself is rigid. Amine blush is fairly common and certain conditions exacerbate it.

Haven't had that problem but it says you can go 2 to 1 and i have been going closer to that than 1 to 1

I use other epoxi, but had the same mistake. For me I noticed it was a thing of mixing, I do it now at twice as long as before - and it is good now.
