Abstract: The invention relates to a copolymer having polyamide PA blocks and polyether PE blocks, in which PA is of diamine.diacid X.Y type; X, the number of carbons of the diamine, is within the range from 6 to 14, and Y, the number of carbons of the diacid, is within the range from 6 to 18. The invention also relates to the use of the said copolymer in a process of direct adhesion between two TPE materials for increasing the peel strength between these materials.

Abstract: “The present invention relates to the use of an encapsulated adhesion promoter in an effective amount in an aqueous adhesive joint, said aqueous adhesive joint being intended to bond a surface of a first substrate (S1) to a surface of a second substrate (S2), at least one of said two substrates comprising a material (TPE-PA) comprising at least one thermoplastic elastomer (TPE) and/or at least one polyamide (PA), said adhesion promoter (P) comprising at least one organic molecule having at least one isocyanate function blocked by encapsulation of said organic molecule.

Abstract: “The invention relates to a method for producing a laminate comprising at least two polymer layers, a layer (A) and a layer (B), which are fixed to each other by at least one aqueous-type adhesive polymer material layer (C).

Abstract: The present invention relates to the assembly by adhesive bonding of a first substrate S1 made of thermoplastic polymer elastomer (abbreviation TPE) or of omopolymeric polyamide (abbreviation PA) or copolymeric polyamide (abbreviation coPA) and of a second substrate S2. The substrates S1 and S2 can be of the same kind, in other words made of TPE or of homopolymeric PA or of coPA, or may be of different kinds. Generally speaking, the thermoplastic polymer elastomer (TPE) substrates S1 are assembled by adhesive bonding with other substrates S2 by means of adhesives or glues based on organic solvent, which are also referred to as two-component solvent-borne polyurethane adhesives.

Abstract: 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.
