Claim 1:
2. The process according to claim 1, wherein the first composition (A) comprises one or more organic C1-C6 alkoxysilanes (A1) of the formula (S-I) and/or (S-II),

R1R2N-L-Si(OR3)a(R4)b  (S-I), where
R1,R2 independently represent a hydrogen atom or a C1-C6 alkyl group,
L is a linear or branched, divalent C1-C20 alkylene group,
R3,R4 are independent of each other for a C1-C6 alkyl group,

a, represents an integer from 1 to 3, and
b is the integer 3-a, and

(R5O)c(R6)dSi-(A)e-[NR7-(A′)]f-[O-(A″)]g-[NR8-(A″)]h-Si(R6′)d′(OR5′)c′  (S-II),, where
R5, R5′, R5″, R6, R6′ and R6″ independently represent a C1-C6 alkyl group,
A, A′, A″, A′″ and A″″ independently represent a linear or branched C1-C20 divalent alkylene group,
R7 and R8 independently represent a hydrogen atom, a C1-C6 alkyl group, a hydroxy-C1-C6 alkyl group, a C2-C6 alkenylgroup, an amino-C1-C6 alkyl group or a group of formula (S-III),

(A″″)-Si(R6″)d″(OR5″)c″  (S-III),

c, stands for an integer from 1 to 3,
d stands for the integer 3-c,
c′ stands for an integer from 1 to 3,
d′ stands for the integer 3-c′,
c″ stands for an integer from 1 to 3,
d″ stands for the integer 3-c″,
e stands for 0 or 1,
f stands for 0 or 1,
g stands for 0 or 1,
h stands for 0 or 1,
wherein at least one of the radicals from e, f, g and h is different from 0,
and/or condensation products thereof.
