Gorilla Super Glue is basically just like regular super glue although I find Gorilla Super Glue to be stronger than regular super glue is.
The technical name for super glue including Gorilla Super Glue is Cyanoacrylate.
I use Gorilla Super Glue all the time when I need to glue something back together and keep some Gorilla Super Glue in my car and truck and in my house and garage.
Gorilla Super Glue is a very good super glue and does work on a lot of surfaces and yes Gorilla Super Glue does work great for gluing plastic together.
Although it might not work on some grades of plastic but all plastics I've needed to glue back together the Gorilla Super Glue has worked great for gluing the plastic back together.
