What kind of 3M VHB tape?

In this video that shortly describes the production of curved ESL, there is a point in the video at 3:00 where tape is applied to the stators to fix the membrane. It's 3M VHB tape but I can't make out what type of VHB tape it could be, there are more then 40 types in the VHB range.
Does anyone have any suggestions?
