USE OF A ADHESION PROMOTER IN A SOLUTION FOR CLEANING THE SURFACE OF A TPE AND / OR PA SUBSTRATE TO INCREASE THE ADHESION OF THE SUBSTRATE WITH AQUEOUS GLUE JOINTS.

摘要

The present invention relates to the use of an adhesion promoter (P) in an effective amount in a cleaning solution (N) to form an adhesion promoter (NP) cleaning solution, said solution (NP) being intended for cleaning the surface of a substrate of material (TPE-PA), that is to say of material comprising at least one thermoplastic elastomer (TPE) and / or at least one polyamide (PA) and / or their (s) mixture (s), and to increase the adhesion of said surface with aqueous adhesive joints, said adhesion promoter (P) comprising at least one organic molecule comprising at least one isocyanate function blocked by at least one blocking agent.
