Unibond 800
« on: September 28, 2015, 06:00:53 pm »
I'm reading some bad things about Unibond 800 and was wondering if anyone can recommend a better glue for south American hardwood to bamboo? Don't want to use Titebond.

  I use both tightbond and smooth on. On multilams where I am using a power lam or any kind of fit that require some force I use the smooth on. On easy layups I use tightbond. No issues with either one.

Not sure what your reading about Unibond? Its fantastic epoxy glue. Ive used it on at least a half dozen hickory and boo backed ipe bows.

I was trying to find it on line and found a forum that said when the guy who was gluing up his veneer it peeled apart after several hours of being clamped. He said the new formula was different than the original.

The only real  problem you can have with urea formaldehyde glues is when they are past their used by dates.

And that one guy is going to turn you off a great product used by bowyers everywhere?

I've done a dozen or so glue ups with Unibond and have never had any problems with it.  Bamboo and hickory backed, tri-lams, power lams, etc.  The label on the can says to keep bent laminations clamped overnight, which is kinda vague.  I keep the clamps on 10 hours.
Smooth On is good though, too.  They both do the job equally well IMO.

I use unibond exclusively for my laminate bows. I've never had a problem.

Tell him to either weigh or measure by volume his mixture next time. Whatever the changes from URAC to Unibond may be? I cant see or feel. It smells the same, looks the same, works the same and cures the same in my shop.

Resorcinol. It's my glue of choice and I will never use anything else.

I'm pretty danged happy with UniBond 800.  The 'new' formulation is as near to being the EXACT same thing as I can tell.  The Nelson Paint Company, the distributor I get Unibond 800 from, says that the new formulation mixes more readily and is more heat tolerant than the old.  NEITHER of which were ever a problem to me before actually, so IF it's different, I don't notice it particularly.

Cool, thanks for all the input. I just hadn't used it before and after seeing the complaint I just wanted to see if anyone else had any problems with it but it sounds like it might have been a fluke on his part. Just ordered it from Nelson paints and am waiting on it's arrival.
