Claim 1:
2. A method according to claim 1, wherein the first composition (A) comprises one or more organic C1-C6 alkoxysilanes (A1) of a 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 independently are a C1-C6 alkyl group,
a represents an integer from 1 to 3,
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″, and A′″ independently represent a linear or branched divalent C1-C20 alkylene group,
R7 and R8 independently represent a hydrogen atom, a C1-C6 alkyl group, a hydroxy C1-C6 alkyl group, a C2-C6 alkenyl group, an amino C1-C6 alkyl group or a group of a formula (S-III),

-(A″″)-Si(R6′)d″(OR5″)c″  (S-III), wherein

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, and

wherein A″″ represents a linear or branched divalent C1-C20 alkylene group,
with the proviso that at least one of the radicals from e, f, g and h is different from 0, and/or their condensation products.
