- the second component which is added to the first component, just before use, and which allows the crosslinking of said first component, is an isocyanate or a mixture of isocyanates.
- the present invention also relates to a method of surface treatment of a substrate TPE in order to promote the attachment of an aqueous type primer or an aqueous type of adhesive on said substrate Sl for assembly by bonding said substrate S1 thus bonded to another substrate S2, characterized in that a substrate adhesion promoter (i) is applied to the substrate S1 either prior to the application of said aqueous type primer and / or said adhesive of aqueous type, as defined above, where appropriate the adhesion promoter being in admixture with at least one cleaning and / or functional solvent as defined above (ii) or simultaneously with an adhesion primer of aqueous type and / or with an aqueous type glue.
- At least one adhesion promoter is applied to the substrate prior to application of an adhesion primer; at least one adhesion promoter is applied to the substrate mixed with an adhesion primer, thus at the same time as the adhesion primer is applied; At least one adhesion promoter is applied to the substrate in admixture with the adhesive in the absence of adhesion primer, therefore at the same time as the adhesive is applied; The adhesion primer and / or the adhesive are applied to the substrate, the adhesion promoter being incorporated into the mass of the substrate.
- the present invention relates to a kit for bonding a thermoplastic elastomeric thermoplastic polymer (TPE) substrate to another substrate S2, said kit comprising:
- PA12-PTMG polyamide 12 polytetramethylene glycol
- 7033 PEBA type PA12-PTMG (polyamide 12 polytetramethylene glycol), marketed by ARKEMA under the name "PEBAX® 7033”.

- WO1 aqueous glue sold by DONGSUNG under the name "Aquace® WOl”.
- the substrates S1 and S2 are plates of dimensions 100 x
- test pieces measuring 100 x 15 x 1 mm were cut with a punch. The test pieces were conditioned in an air-conditioned room (23 ° C., 50% RH) for 48 hours.
- the peel test for measuring the peel force, was carried out on a ZWICK 1445 (WKM 048) at A12, at 18O 0 C, according to the method "Peeling, 500N sensor, at 100mm / min", in which measures the force as a function of the distance of the jaws of the apparatus (elongation). A regular curve shows a plateau, showing uniform adhesion to the entire test piece.
- activation means the application according to the invention of an adhesion promoter.
- Example 5 shows with respect to Example 3 that activation can be further increased by heating the adhesion promoter.
- Example 6 although of the invention because a good adhesion is obtained, shows that the activation by heating must be regulated by the skilled person in order to obtain an optimized activation.
- Example 7 shows, with respect to Example 3, the effect of choosing the adhesion promoter.
- Figures 1, 2 and 3 show schematically the multilayer structure respectively of Ex 3, Ex 11 and Ex 12.
