From Wikipedia;
Cyanoacrylate is the generic name for a family of fast-acting adhesives with industrial, medical and household uses.
They include methyl 2-cyanoacrylate, ethyl-2-cyanoacrylate (commonly sold under trade names like "Super Glue" and "Krazy Glue"), and n-butyl cyanoacrylate (used in veterinary and skin glues). The related compound 2-octyl cyanoacrylate is a medical grade glue; it was developed to be non-toxic and less irritating to skin tissue. Cyanoacrylate adhesives are sometimes known as instant glues. The abbreviation "CA" is commonly used for industrial grades.
so yes Super Glue is Cyanoacrylate (CA).
As a finish, use the super thin stuff and rub it in while it's still 'wet' and it will form a good hard shiny surface. Best done on small areas, not whole bowls! Pen turners us it as a vary hard wearing finish (I've seen up-to 10 coats applied). Personally I use it on the small foot area of my vases etc.
