USE OF AN ADHESION PROMOTER IN A SOLUTION FOR CLEANING THE SURFACE OF A SUBSTRATE BASED ON TPE AND/OR ON PA FOR INCREASING THE ADHESION OF THE SAID SUBSTRATE TO AQUEOUS ADHESIVE BONDS

摘要

Use of an adhesion promoter in a cleaning solution to clean the surface of a substrate in material comprising at least one thermoplastic elastomer and/or at least one polyamide, and to increase the adhesion of the surface with aqueous glue joints, and where the adhesion promoter comprises at least one organic molecule comprising at least one isocyanate function blocked by at least one blocking agent, is claimed. Independent claims are included for: (1) a process for assembling of the two substrates (first and the second) using aqueous glue joint, where the at least one of the two substrate is in the material comprising thermoplastic elastomer and/or polyamide, comprising cleaning of the surface and/or substrate with the cleaning solution comprising the promoter, applying the aqueous glue joint on the surface of at least one of the two substrate, docking of the surface comprising the aqueous glue joint of the substrate with an another surface of substrate to form an assembly comprising two substrates with the aqueous glue joint between them, pressing the whole, and recovering all in the form of a laminated product; and (2) a laminated product, preferably shoe sole, comprising first substrate and second substrate adhering to one another by means of the aqueous glue joint, where the surface of at least one of the first and second substrate comprises at least one adhesion promoter; and (3) the adhesion promoter cleaning solution to increase the surface of substrate in the material comprising thermoplastic elastomer and/or the polyamide, where the solution comprises the adhesion promoter to increase the adhesion of the surface by aqueous glue joints.
