Beschreibung
Zusammenfassung:	Die Zusammensetzungen umfassen die Komponenten (A) siliciumorganische Verbindungen mit Kohlenwasserstoffresten, Hydroxylresten und/oder Alkoxyresten und (B) fluororganische Siloxanverbindungen, die mindestens einen organischen Rest enthalten, der einen Fluoralkylrest aus 4 bis 20 Kohlenstoffatomen aufweist, wobei die Kohlenstoffatome der Fluoralkylreste mit mindestens 90 Mol-% Fluoratomen gesättigt sind. Formulations comprise the following components: (A) organosilicon compounds of formula (I); and (B) at least one fluorinated organic siloxane compound of formula (IIa), at least five fluorinated organic siloxane compounds of formula (IIb) and optionally fluorinated organic siloxane compounds of formula (IIc). Ra(OR )bSiO(4-a-b/2) (I), ER xSiO(3-x/2) (IIa), R ySiO(4-y/2) (IIb), E R zSiO(3-z/2) (IIc) R, R = 1-20C hydrocarbon bonded to Si via C atom; R = H or 1-6C alkyl; E = organic group containing at least one 4-20C fluoroalkyl group in addition to a further 3-200 atoms chosen from C, H, O, N and Cl, in which at least 90 mol.% of the C atoms in the fluoroalkyl groups are saturated with F atoms; E = E or an organic group containing 3-200 atoms chosen from C, H, O, N and Cl; a, z = 0-3; b = 1-4; and x, y = 0-2. A method for treating porous materials to make the oil and water repellent by applying the above formulation is also claimed.
