Excessive amount, I sense, is adhesive (9)
I believe the answer is:
glutinous
'is adhesive' is the definition.
(similar in meaning)
'excessive amount i sense' is the wordplay.
'excessive amount' becomes 'glut' (I've seen this before).
'sense' becomes 'nous' (nous is a kind of sense).
'glut'+'i'+'nous'='GLUTINOUS'
(Other definitions for glutinous that I've seen before include "Sticky" , "not easy to shake off?" .)
