Silane-crosslinking adhesive or sealant comprising n-silylalkylamides and use thereof

A silane-crosslinking adhesive or sealant containing a polymer made up of an organic backbone that carries at least two alkoxy- and/or acyloxysilyl groups, wherein, as further components, compounds of formula (I)

• in which
• R1 is a straight-chain or branched, substituted or unsubstituted alkyl residue having 1 to 24 carbon atoms,
• R2 is a hydrogen residue or a straight-chain or branched hydrocarbon residue having 1 to 10 carbon atoms,
• R3 is an alkoxy residue having 1 to 8 carbon atoms or an alkyl residue having 1 to 24 carbon atoms,
• R4 is a straight-chain or branched alkylene residue having 1 to 8 carbon atoms, in which carbon atoms can be substituted with nitrogen or oxygen atoms,
• n=1 to 8, preferably n=3 to 8,
• such that the residues R3 can each be the same or different, and at least two of the residues are alkoxy residues,
• are contained as an additive.
