Pioneers waving around axes stick together with this? (5,5)
I believe the answer is:
epoxy resin
'stick together with this?' is the definition.
(epoxy resin can stick things together)
'pioneers waving around axes' is the wordplay.
'waving' indicates an anagram (letters wave around).
'around' is an insertion indicator.
'axes' becomes 'xy' (x axis and y axis).
'pioneers' with letters rearranged gives 'eporesin'.
'eporesin' placed around 'xy' is 'EPOXY RESIN'.
(Other definitions for epoxy resin that I've seen before include "synthetic material" , "This used to surface" , "compound" , "Synthetic adhesive" .)
