摘要

Solution, and in particular for pretreating a hydrophilic surface for the hydrophobicization, consisting ofI. at least one silane of the formula # # str1 # # withR¹, R², R³ independently of one another are selected from the group consisting of methyl, ethyl, 2 - methoxyethyl, propyl, i - propyl, butyl, benzylm = 0 or 1n = 3 to 12p = 1 or 2and, when p = 1Y = a functional group selected from the group consisting of(Meth) acrylic, (meth) acryloxy, mercapto, ureido, - nh - ch₂-Ch₂-Nr⁴R⁵, -Nr⁴R⁵ (with r⁴ and r⁵ independently of one another are selected from the group consisting of h, alkyl, phenyl, benzyl, cycloalkyl),orfor p = 2Y = nhandIi. at least one second, the aging stability, which increases silane with not more than two carbon atoms in chain bound to the silicon.
