The invention relates to an aqueous composition based on tris-silylated amino-functional silicon compounds, which is substantially free of organic solvents and which substantially does not release any alcohol even during the cross-linking process, and to method for the production thereof, and to the use thereof, for example for the hydrophobization of metal, glass or mineral surfaces, such as concrete and bricks, as adhesion promoter or for rock consolidation, among other things. 3. The composition of claim 2 , wherein: {'br': None, 'sup': 1', '11', '11', '1, 'sub': 3-Δ', 'Δ', 'Δ', '3-Δ, '(OR)(R)Si-A-Si(R)(OR)\u2003\u2003(II)'}, 'A is derived from formula (II)'}wherein {'br': None, 'sub': 2', 'f', 'g', '2', 'f*', 'g*, '—Z*—[NH(CH)]NH[(CH)NH]—Z*—\u2003\u2003(III)'}, 'A is a bivalent amino-functional group of the formula (III)'}Z* is independently a bivalent alkylene radical, and f, f*, g or g* are the same or different,f and/or =1, 2 or 3,g and/or g*=0, 1 or 2, and{'sup': '11', 'claim-text': {'br': None, 'sup': 12', '1, 'sub': Ω', '3-Ω', '3, 'N[ZSi(R)(OR)]\u2003\u2003(IX)'}, 'Z is derived from formula (IX)'}, 'Ris a linear, branched and/or cyclic alkyl radical having 1 to 24 carbon atoms or an aryl radical;'}whereinZ is independently a bivalent alkylene radical, and{'sup': '12', 'Ris a linear, branched and/or cyclic alkyl radical having 1 to 24 carbon atoms or an aryl radical, and,'} {'br': None, 'sup': 3', '1, 'sub': x', '3-x, 'B—Si(R)(OR)\u2003\u2003(IV)'}, 'B is derived from formula (IV)'}, 'Ω is, independently, 0 or 1;'}whereinx=0 or 1,{'sup': '3', 'Ris a linear, branched or cyclic alkyl radical having 1 to 24 carbon atoms and/or an aryl radical, and'} {'br': None, 'sup': '10', 'sub': h*', '(2-h*)', '2', 'h', 'j', '2', 'l', 'n', '2', 'k, 'RNH[(CH)(NH)][(CH)(NH)]—(CH)—\u2003\u2003(Va)'}, 'B is one of the following amino-functional groups of formula (Va) or (Vb)'}wherein0≦h≦6,h*=0, 1 or 2,j=0, 1 or 2,0≦1≦6;n=0, 1 or 2,0≦k≦6, and{'sup': '10', 'claim-text': {'br': ...
