Clear Gorilla Glue

[lanternnate]

Here is what it looks like cured. Put two drops on some scrap rosewood. Left one just as a blob and spread the other out. The bubbles in the blob are just air bubbles from coming out of the container that I didn't bother to agitate out. As you can see it dries very clear.

How hard is it?

The thing I hate about original gorilla glue is how it expands, even when clamped, that expansion has to go somewhere.

Looks to be some sort of Silanol silicone based adhesive? SDS says give off Methanol on curing. Silanols do this.
The rest may be promoters or plasticizers. Interesting they do not claim what the inerts are on the SDS, but they are not bound to do this.

I'm not sure of a good way to test hardness. If there is something you want me to try with it, let me know and I'll be glad to. Seems pretty hard to me. More plasticy than rubbery if that makes sense. I pushed the point of a small round file into the blob drop. It didn't go into the cured glue and only left a mark that actually rubbed back off with my thumb. I didn't really reef on it because I didn't want a file through my hand, but it held up to moderate pressure.

This stuff doesn't expand at all. I don't know what it is chemically, but whatever it is, it's very different than regular gorilla glue.

That's all I was wondering really, how it compared in hardness to say T-88 or other epoxy. Whether a fingernail would dent it, or if a metal object would, etc.
