The present invention relates to the use of an adhesion promoter (P) in an effective amount in a cleaning solution (N) in order to form an adhesion promoter cleaning solution (CP), the said solution (CP) being intended to clean the surface of a substrate made of (TPE-PA) material, that is to say of material comprising at least one thermoplastic elastomer (TPE) and/or at least one polyamide (PA) and/or their blend(s), and to increase the adhesion of the said surface to aqueous adhesive bonds, the said adhesion promoter (P) comprising at least one organic molecule comprising at least one isocyanate functional group masked by at least one masking agent.
La présente invention concerne l'utilisation d'un promoteur d'adhérence (P) en quantité efficace dans une solution de nettoyage (N) pour former une solution de nettoyage promoteur d'adhérence (NP), ladite solution (NP) étant destinée à nettoyer la surface d'un substrat en matériau (TPE-PA), c'est-à-dire en matériau comprenant au moins un élastomère thermoplastique (TPE) et/ou au moins un polyamide (PA) et/ou leur(s) mélange(s), et à augmenter l'adhérence de ladite surface avec des joints de colle aqueux, ledit promoteur d'adhérence (P) comprenant au moins une molécule organique comportant au moins une fonction isocyanate bloquée par au moins un agent bloquant.
