Abstract

Adhesive bonding of eloxated aluminum to plastic, with a product having at least one layer of a latently reactive adhesive film which has a thermoplastic component having a melting point T(melting) where 35° C.≦T(melting)≦90° C. and contains functional groups that can react with isocyanate and an isocyanate-containing component dispersed in particulate form in the thermoplastic and is essentially deactivated in the region of the particle surface, the particles having a start temperature T(start) where 40° C.≦T(start)≦100° C. and where T(start)≦T(melting).

Claims (4)

1. A laminate consisting of

an eloxed aluminum element,

a double-sided adhesive product having at least one layer of a latently reactive adhesive film which comprises a thermoplastic component, which has a melting temperature T(melt) of 35° C.≦T(melt)≦90° C., and which comprises functional groups that are able to react with isocyanate, and an isocyanate-containing component, which is present in particulate dispersion in the thermoplastic component and is substantially deactivated in the region of the particle surface, the particles having an onset temperature T(onset) of 40° C.≦T(onset)≦100° C., and wherein T(onset)≧T(melt), and

a plastic substrate.
