Hello!
Pattex makes a type of instant adhesive called "GLASS" adhesive.
It's not cheap, but it's very sturdy - provided you follow the instructions!
We use an adhesive specifically designed for mounting glass break sensors on glass panes for alarm systems, and this adhesive even has VdS approval.
Best regards from Munich!
