How long does it take for Fujik glue to dry/cure (potting)?

Hi,

I understand that the thicker it is, that Fujik glue (https://www.fasttech.com/p/1049304) takes longer, but I was wondering, when you use it to pot (so lots of it), does anyone know how long it takes for it to cure/dry?

Thanks,
Jim

I don’t really know myself. I guess it depends on how much you used.
I usually just let mine set over night. Good to go the next day.

Thanks. I guess I won’t sit here watching it dry/cure then :)!

It needs air to cure and potting reduces suface area. It can take more than a day if enclosed. Leaving it in a warm place(not too hot or in the sun or it can expand) helps.

I asked this question yesterday, and as Sirius9 pointed out it should takes around 12 hours .

I have the same tube of Fujik glue but I think if you read the description on it regarding it being
“greaselike” , It’s been my experience that it never really sets like a silicone caulking. It remains
like a paste (or grease).

Hi,

I know that you said that you got the same tube of Fujik glue, but FYI, it’s only been several hours now since I put the 1st layer (I’ve been filling it in in layers), and it’s already somewhat hardened, about the consistency of rubber.

I also know the FT description is not very clear, but the reviews there indicate this is “glue”, and that seems to be what it is, at least the stuff that I got from FT.

The glue comes in a tube, the grease comes in a small tub. Layering sounds like a good idea.
