What glue is this ?

[wefalck]

In the video below on the assembly of SHIPYARD laser-cut blocks the guy uses a liquid, honey-like glue, that seems to set quite rapidly. What kind of glue may this be ?

 

 

Wrote to the guys a week ago, but no response yet ...

Clear, quick set, absolutely no shear stress or prise struss -  cellulose nitrate adhesive - Duco here-  maybe Ambroid in some places?

 

I would not use it to assemble a model, but it is quick and dirty to fit a round toothpick into a piece of stiff packing foam to use as a custom size PVA spreader, applicator.

Well, I would like to know too, it looks useful.

The 'honey' looks and behaves exactly like an industrial acid catylised resin adhesive I used in the '80s. It can't be that same product because that was a two-part adhesive: the 'honey' was put on one component and the acid catalyst was brushed on the other part. When the two were brought together you had about 20 seconds of wriggle-time before a sudden bite occured. The bond was very strong and full strength was achieved in minutes.

The 'honey' behaved exactly like the goo in the video and I used it in a very similar way many times. It would not surprise me at all to find this is a 21st century new-and-improved version. If so, I hope it doesn't smell like the '80s version.

Will be watching for news.

Just looks like a thick hide glue variant to me.  Nothing special, and if made for purpose may explain why its in a nondescript bottle.

Hide glue is normally used warm, isn’t it ?

In most cases yes.   But Titebond sells a type that looks almost exactly like the stuff in that video that is ready to use with no heat.   Also, there is nothing to say the person in the video didn't have that jar on a warmer....    Its just a guess, but it looks like hide glue, or maybe "Old Brown Glue," another variant of similar make.

Titebond hide glue uses water rather than heat to soften and can be reactivated with water. I have, one one occasion, needed to undo a glued joint, about 40mm square so it took a bit of soaking to get right in but it came apart ok, and the original glue just needed a dab top-up when it came to reassembling.

 

Apart from being an indoor adhesive the only downside, for some uses, is setup time, I think they recommend 30 or 60 minutes clamp time (full strength 24 hours). I've used it on a leatherwork stitching pony where it's under considerable stress with no problems.

Reminds me of Gorilla polyurethane glue

[thibaultron]

Doesn't the Gorilla glue take 24hrs?

[vaddoc]

Can't remember, used it once years ago and it went very wrong. Then the bottle solidified and we both moved on...

I think it's likely that it is Butapren, a kind of super strong rubber cement. I've seen it sold on a Polish paper modeler shop site that has some connection to Shipyard. It's commonly sold in tube form, but I think it can be purchased by the can. But, I've only seen it with Polish label, so you'd probably have to find some local equivalent.

That could be. In Germany the classical polychloroprene glue is Pattex and in my youth it was sold in tins. However, it was much for 'stringy' thatn the stuff in the video.

[Dziadeczek]

If it is Butapren (which I think it is), than its equivalent in the US is contact cement.

Butapren also stinks fiercely, so I wouldn't use it for shipmodeling...

[wefalck]

Every organic solvent has a smell and some of them smell quite nicely (no, I am not a 'sniffer' ...). It depends on how big the area is to which you apply the glue. The main point is, whether the glue does the job. And: traditional hide glue does not necessarily smell very nice either.

[EricWilliamMarshall]

It looks like the liquid hide glue previously mentioned to my eye in both viscosity, color and ‘stringiness’. 

[wefalck]

Yes, that could be. Some kind of glutin glue kept from gelling by adding salt.

 

Or it could be a thick shellac solution, one with lots of shellac and little alcohol.

[EricWilliamMarshall]

I would vote against shellac. The color is in the ballpark of white/colorless/bleached shellac (dewaxed as well) but stickiness seems incorrect for the color.  Not that it isn’t possible, just I vote against. 

[EricWilliamMarshall]

I see that one of the comments in the video is also a request regarding the question of glue type. Perhaps an answer will arrive in a year or two...
