The invention relates to crosslinkable compositions of silane-crosslinking prepolymers comprising (A) 100 parts by weight of silane-crosslinking polymers of the formula (I): Y-[(CR1 2)b-SiRa(OR2)3-a]x, where the radicals and indices are each as defined in claim 1, (B) 5 to 100 parts by weight of fumed silica comprising (B1) fumed hydrophilic silica and (B2) fumed hydrophobic silica, with the proviso that (B1) and (B2) are used in a mass ratio of 10:1 to 1:10, to processes for production thereof and to the use thereof as adhesives and sealants, especially for bonding of substrates. |
