The present invention is directed to an aqueous adhesive composition comprising a functionalized polyolefin, a cross-linking agent, and a cross-linkable resin as well as to a process for adhering a thermoplastic elastomer composition to a substrate comprising the steps of applying said aqueous adhesive composition to a polar substrate and applying the thermoplastic elastomer, for instance, by extrusion, in particular, by robotic extrusion.
摘要:
The invention relates to a method for adhering two substrates, namely a first substrate A and a second substrate B, to each other using a latent-reactive adhesive film with at least one latent-reactive adhesive film layer which has a thermoplastic component with a melting temperature T(melt), where 35°C ≤ T(melt) ≤ 90°C, said thermoplastic component containing functional groups that can react to isocyanate, and an isocyanate-containing component that is dispersed into the thermoplastic component in a particulate form and is blocked, microencapsulated, or substantially deactivated in the region of the particle surface. The particles have a start temperature T(start) of 40°C ≤ T(start) ≤ 120°C, wherein T(start) ≥ T(melt). A surface of the first substrate A is brought into contact with a first surface of the latent-reactive adhesive film, and a surface of the second substrate B is brought into contact with the second surface of the latent-reactive adhesive film. The adhesion is caused by heating the latent-reactive adhesive film to a temperature which corresponds to or is higher than at least the start temperature T(start). The invention is characterized in that at least the surface of the first substrate A which is brought into contact with the latent-reactive adhesive film is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film, and/or at least the first surface of the latent-reactive adhesive film which is brought into contact with the first substrate A is treated with a primer before the first substrate A is brought into contact with the latent-reactive adhesive film.
