Gorilla glue, also available from Titebond, and others, is polyurethane glue. Not really as strong as epoxy, but very strong, and yes it expands quite a bit. It will also make your hands, or any other skin it touches black, so it's a good idea to wear surgical gloves, or the like. Don't forget to read the directions though, as many have poor results from not dampening one surface with water first- especially on foam, or hard woods. As for shelf life, make sure to squeeze out all extra air before closing it and hang the bottle upside down. The Titebond bottle has a hole at the bottom for this purpose.
