It's two resins that are, sort of, in and of themselves -- neither of which can make glue, but when you put the two together, something happens. A bond takes place, and you get this very strong, powerful adhesive.
Són dues resines, més o menys, i tota sola, cap de les dues serveix de pega, però quan es barregen, passa quelcom. Es crea un enllaç i el resultat és un adhesiu fort i resistent.
