Use of a mixture of 5 to 95% by weight of an azidosilane of the general formula N3-R³-Si-R¹n (OR²) 3-n I wherein R¹ is a C1-C3-alkyl, a phenyl, benzyl or toluyl group, R² for a C1-C4-alkyl, C2-C4-alkoxyalkyl, a phenyl or benzyl group, R³ for a C1-C8-alkylene group which is represented by an oxygen atom, sulfur atom or a - (NR <4>) group, in which R 4 represents a hydrogen, a methyl, ethyl or phenyl group, can be interrupted, and n represents 0, 1 or 2, and 5 to 95% by weight of an aminoalkoxysilane of the general formula H2N-R <5 > -Si-R <6> m (OR <7>) 3-m II where R <5> for a C1-C6-alkylene, a C5-C6-cycloalkylene or arylene group, which are additionally represented by one or two C1-C3-alkyl groups can be substituted and R6 and R7 independently of one another for a C1-C6-alkyl or a C5-C6-cycloalkyl group, which are also additionally substituted by one or two C1-C3-alkyl groups can stand and m = 0, 1 or 2 se in, as an adhesion promoter between polycondensates, which have heterocyclic ring systems with N atoms as structural units or precursors of these polycondensates and inorganic substrates. |
