The invention relates to a solution, in particular for pre-treating a hydrophilic surface for hydrophobization, comprising: I. at least one silane of the formula (1) where R1, R2, R3 independently of one another are selected from the group consisting of methyl, ethyl, 2-methoxyethyl, propyl and i-pr
The invention relates to a solution, in particular for pre-treating a hydrophilic surface for hydrophobization, comprising: I. at least one silane of the formula (1) where R1, R2, R3 independently of one another are selected from the group consisting of methyl, ethyl, 2-methoxyethyl, propyl and i-propyl, butyl, benzyl m=0 or 1, n=3 to 12, p=1 or 2, and, for p=1, Y=a functional group selected from the group consisting of (meth)alkyl, (meth)acryloxy, mercapto, ureido, —NH—CH2—CH2-NR4R5 and —NR4R5 (where R4 and R5 independently of one another are selected from the group consisting of H, alkyl, phenyl, benzyl, cycloalkyl), or, for p=2, Y=NH; and II. at least one second silane increasing the aging stability having no more than two carbon atoms bound to the silicon in a chain.

1. A solution particularly for the pretreatment of a hydrophilic surface for hydrophobizing, comprising (i) a first silane having the formula wherein R1, R2, R3 independently of one another are selected from the group of methyl, ethyl, 2-methoxyethyl, propyl, isopropyl, butyl, benzyl, andm=0 or 1; n
1. A solution particularly for the pretreatment of a hydrophilic surface for hydrophobizing, comprising (i) a first silane having the formula wherein R1, R2, R3 independently of one another are selected from the group of methyl, ethyl, 2-methoxyethyl, propyl, isopropyl, butyl, benzyl, andm=0 or 1; n=3 to 12; p=1 or 2; and with the proviso that when p=1, then Y=a functional group selected from the group of (meth)acryloyl, (meth)acryloyloxy, mercapto, ureido, —NH—CH2—CH2—NR4R5, —NR4R5 (with R4 and R5 independently of one another selected from the group of H, alkyl, phenyl, benzyl, cycloalkyl),and when p=2, then Y=NH;(ii) a second, aging stability enhancing silane having the formula wherein R8=H, alkyl, phenyl, benzyl or cycloalkyl; and(iii) a third silane having the formula Si(OR9)4 wherein R9=methyl, ethyl, n-propyl, isopropyl, butyl, isobutyl, benzyl, phenyl. 2. The solution of claim 1, wherein the silanes are in solution in a nonprotic solvent or in a solvent mixture in which a nonprotic solvent is present at not less than 30% by weight. 3. The solution of claim 2 wherein the silanes in total are present in a concentration of 0.01% to 8% by weight in the solvent or solvent mixture. 4. The solution of claim 2 wherein the solvent is composed at least to an extent of 30% by weight of carboxylic esters. 5. The solution of claim 2 wherein the solvent possesses a boiling point between 35° C. and 180° C. 6. The solution of claim 1 wherein the ratio between the second silane and the third silane is 1:2 to 4:1. 7. The solution of claim 1 wherein the solution is present in the form of a pump spray or an aerosol. 8. The solution of claim 1 wherein the solution is dispensed into sealed-edge pouches containing a nonwoven or woven material or a sponge. 9. The solution of claim 1 wherein the solution is dispensed into containers containing a reservoir and an applicator and can be applied contactlessly. 10. The solution of claim 8 wherein the solution is located in a pack into which a nonwoven material or a sponge have been integrated such that they are located on the free surface of the pack, the solution separate from the nonwoven material or from the sponge as a result of a severable membrane, or which is enclosed by an envelope and in this way is separate from the nonwoven material or sponge.
