Well about liquid nails, that dries softer than something like Gorilla glue. They're both crosslinked polyurethane, and if a tiny amount (1 mL or so) is added to 100 mL of gorilla glue, it dries extremely hard. I have a pending patent involving crosslinking polyurethanes and Gorilla glue has the best properties if you want to get rid of the rubber's "give". |
