The present invention relates to the assembly by adhesive bonding of a first substrate S1 made of thermoplastic polymer elastomer (abbreviated TPE) or of homopolymeric polyamide (abbreviated PA) or copolymeric polyamide (abbreviated coPA) and of a second substrate S2. The substrates S1 and S2 may be of the same kind, in other words made of TPE or of homopolymeric PA or of coPA, or may be of different kinds. Generally speaking, the thermoplastic polymer elastomer (TPE) substrates S1 are assembled by adhesive bonding with other substrates S2, by means of adhesives or glues based on organic solvent, which are also referred to as two-component solvent-borne polyurethane adhesives.
