Abstract
Use, as adhesion promoter intended for application to the surface of a substrate S1 made of thermoplastic elastomer polymer TPE which comprises a chain formed of an alteration of hard segments and of soft segments, for the purpose of the adhesive assembly of the said substrate S1 with another substrate S2, of at least one solvent of the hard segments and/or of the soft segments of the said thermoplastic elastomer polymer TPE.

1-11. (canceled)
A process for the surface treatment of a substrate S1 made of thermoplastic elastomer polymer in order to promote the attachment of an aqueous adhesive system for the purpose of the adhesive assembly of a substrate S1 made of thermoplastic elastomer polymer with another substrate S2, comprising the step of applying an adhesion promoter to the substrate S1.

A kit for the adhesive assembly of a substrate S1 made of thermoplastic elastomer polymer with another substrate S2, said kit comprising:
- an adhesion promoter, optionally a cleaning solvent and/or a functional solvent,
- at least one of an aqueous adhesion primer intended for coating S1 and an aqueous glue or adhesive intended for coating the substrate S1 with adhesive, and
- at least one of an aqueous or solvent-based adhesion primer intended for coating the substrate S2 and an aqueous or solvent-based glue or adhesive intended for coating the substrate S2 with adhesive.
An adhesive assembly comprising at least two layers of substrate S1 and S2 bonded by means of at least one aqueous adhesive system, at least one of the substrates being a thermoplastic elastomer polymer (TPE) having been activated by an adhesion promoter which is a solvent selected from the group consisting of butanediols, 1,3-butanedio, 1,4-butanediol, metacresol, carvacrol, glycerol, glycols, butyl glycol, butyl diglycol, butanols, n-butanol, isobutanol, benzyl alcohol, limonene, and mixtures thereof.
