 Pierre,

         I'm not sure what the chemical is for lamiating two sheets of Plexiglass together is.  But where ever they sell acrylic they usally have it on hand.  I know it is very volitile and you should have good venilation when using it.  As with most such materials you don't want to breath it !  I will try and find the name of it.
