      1 and R
      2 are mutually independently alkyl, cycloalkyl and/or aryl, a is 0, 1 or 2, b is 1, 2 or 3 and the sum of a and b is 3, and b) a mixture of straight-chain and/or cyclic siloxanes of the general formulae (I) and/or (II), in which the individual moieties (R) are mutually independently alkoxy, alkoxyalkoxy, alkyl, alkenyl, cycloalkyl and/or aryl and some of the moieties (R) are aminoalkyl-functional groups of the formula -C

These have excellent suitability for application as adhesives and sealants, while featuring improved adhesion more particularly on substrates that are not easily bonded to one another.
