'binding material' is the definition.
'glue' can be an answer for 'material' (glue is a kind of material). I'm not sure about the 'binding' bit.

'gel's used regularly' is the wordplay.
'regularly' means one should take alternating letters (regularly take one letter, leave next etc.).
'gels'+'used'='gelsused'
The alternate letters of 'gelsused' are 'GLUE'.
