Abstract:
1. A method for adhesive bonding of surfaces, comprising applying to at least one of said surfaces a foamable mixture (M) comprising (A) at least one prepolymer (A) having groups of the formula [1] in which A is a divalent binding group selected from —O—, —S—, —(R R R R x is a number from 1 to 10, a is a number from 0 to 2, and (B) at least one blowing agent (B), and foaming the foamable mixture (M) on at least one of said surfaces to be adhesively bonded or between said surfaces to be adhesively bonded to give a foam (MS), or applying a foam (MS) which has been prepared from the mixture (M) to at least one of said surfaces to be adhesively bonded or between the surfaces to be adhesively bonded, the foam (MS) having a foam structure comprising gas bubbles, and pressing the foam (MS) between the surfaces to be adhesively bonded, wherein the foam structure of the foam (MS), when it has been pressed between the surfaces to be adhesively bonded, is destroyed in part, such that the foam, after pressing, comprises less than 60% of gas bubbles, based on its volume, and curing the foam.
