Z2 grip pads - replacement adhesive?

Z2 grip pads - replacement adhesive?

When discovering that my Z2's thumb-area grip pad began to slide  out of its recessed location, I was happy to find  this Knowledge Base article - https://support.swiftpoint.com/portal/en/kb/articles/pro-range-grip-replacements.   Besides offering the helpful opportunity to purchase replacements if needed it also suggests that users could, after  cleaning the old adhesive  residue off with isopropyl alcohol,  return the grip either using a permanent adhesive, or a new 'light' adhesive.     

I can appreciate the original choice of the "light" adhesive as intended to allow user repair and replacement of the Z2 Grip Pads, but if the Swiftpoint team could please specify what specific adhesive types they're referencing? I want to ensure  that I use  the same or something close, suitable for the silicon grip pads used on the Z2.   Thank you.
