Looking for a smooth on equivalent that I can get in the U.K.
Any thoughts guys?
-
Can you get Unibond? Made by Nelson Paint Co. (US) If not try Weldwood Plastic Resin. It is a urea glue like Unibond(Urac185 was the original) in powder form and all you do is add water to mix. I learned about Weldwood Plastic Resin from a guy from Italy and it worked well for me.

I can't get unibond but I can get weldwood.
Does it need air to cure? Or does it cure like an epoxy?
-
It's a chemical reaction like Urac or Unibond. It cures at room temp(approx. 70 deg (F)) but cures faster at higher temps. I haven't used it in a few years so I don't remember the specifics about it. It is relatively inexpensive here. Maybe do a test with it first before you trust it to a bow but I glued hickory and boo backings on different woods and riser blocks and never had a glue failure.
-
You can also get 'Cascamite" there. Pretty sure it's more or less the same thing as Weldwood.
-
Resorcinol, Cascamite, Resintite or a bog standard 2 part epoxy all work for gluing up bows. I didn't believe the 2 part epoxy would work, but somebody I shoot with makes heavy laminated warbows using epoxy with no failures yet.
-
Thanks for the replies.
Any brands of epoxy that could be recommended? Again, that I can get in the UK.
-
You can get Araldite and WEST G-Flex from Axminster. They also have the equivalent of Urac and Resorcinol.
You have many choices and some would say the last two are better than Epoxy.
-
Bloke I shoot with in the UK swears by Araldite 2 part epoxy, the stuff in the tubes. One set of tubes does one lamination, so you'd need two packs for a tri lam.
-
i began using weldwood when URAC went under a few years ago at Pat Bs suggestion and I have been happy. I have had no major issues with it, and it was quite inexpensive compared to the others. I only use it though when working w Bamboo. Wood to wood I still use TBIII.

Humbrol Extraphen (resourcinol) for me. Super tough 2-pack adhesive. Sticks any wood to any other, including oily exotics, in my experience.
-
I use Resintite.
I have also used a 2hour epoxy. Araldite is ridiculously expensive.

That's true. I would imagine any 2 part epoxy is the same as Araldite. You can get those good 151 ones in most shops.

They differ hugely in properties, I got the 2 hour one from a model supplies place, can't remember the name, but they had loads of good stuff at reasonable prices in sensible quantities.

Wow, there really is a whole world of glue out there!
Thank you for all the replies, it's been most helpful!
Just to clarify can I completely wrap a glue up, if using one of the urac style urea formaldehyde powdered glues? Or does it need air to cure?
-
Hi there.
You can get Smooth On in the UK. Flybow in Ireland will post it to you.

AFIK it doesn't need air.
I completely wrap Resitite which is (I believe) that type of glue.. it's certainly a powder.

Thanks guys. Yeah, flybow is where I checked first, unfortunately they aren't processing orders until the 19th of September. I might try two glue ups, one with epoxy and one with urea glue. I'm new to laminating, so I guess I'll see which I prefer.
I do have plenty of titebond 3 as well, might try all three.
