Abstract: Liquid, fluorine-containing bicomponent composition comprises a fluorosilane component (A) with a polymer bounded fluorine content of 5-95 wt.% and a polymer bounded silicon content of 95-5 wt.%, where (A) is obtained by e.g. (a) reacting (per)fluoroalkylalkylene isocyanate component (Biv) with amino silane component (Ei)/(Eii) to obtain an adduct, silanizing a stabilizing component (T), (c2) neutralizing the amino functional adduct with an acid component (Uiv); (d) reacting the components (A) and (T), with an activator component (X), and (e) adding a formulation component (Yi) and/or (Z). Liquid, fluorine-containing bicomponent composition with a solid resin having a fluorine content of 5-75 wt.%, comprises a fluorosilane component (A) with a polymer bounded fluorine content of 5-95 wt.% and a polymer bounded silicon content of 95-5 wt.%, where (A) is obtained by e.g. (a) either reacting 5-95 wt.% of a (per)fluoroalkylalkylene isocyanate component (Biv) of formula (CF 3-(CF 2) x-(CH 2) y-NCO) or (C(R) 3-(C(R) 2) x-(CH 2) y-NCO) with 95-5 wt.% of an amino silane component (Ei) and/or (Eii) to obtain an adduct of formula ((Biv)-(E)), or reacting two or more hydroxyl groups of 5-95 wt.% of a (per)fluoroalkylalkane carboxylic acid (derivative) component (Bv) of formula (CF 3-(CF 2) x-(CH 2) y-COR 4>) or (C(R) 3-(C(R) 2) x-(CH 2) y-COR 4>) with 95-5 wt.% of the component (Ei) and/or (Eii), and removing a residue of formula (HR 4>) (I) to obtain an adduct of formula ((Bv)-(E)), or reacting 5-95 wt.% of hexafluoropropene oxide component (Fi) consisting of monofunctional hexafluoropropene oxide oligomer of formula (CF 3-CF 2-CF 2-O(CF(CF 3)-CF 2-O) n-CF(CF 3)-COR 4>) with 95-5 wt.% of the component (Ei) and/or (Eii), and removing (I) to obtain an adduct of formula ((Fi)-(E)), or reacting 5-95 wt.% of a hexafluoropropene oxide component (Fii) consisting of difunctional hexafluoropropene oxide oligomer of formula ((R 4>OC-CF(CF 3)-(O-CF 2-CF(CF 3)) n-O-(CF 2) o-O-(CF(CF 3)-CF 2-O) n-CF(CF 3)-COR 4>) with 95-5 wt.% of the component (Ei) and/or (Eii), and removing (I) to obtain an adduct of formula ((Fii)-(E)), or reacting 5-95 wt.% of (per)fluoroalkylalcohol component (Bia) and/or (per)fluoroalkylalkyleneamine component (Bii) and/or a fluoromodified macro monomer (Biii) with 75-5 wt.% of the component (Ei) and/or (Eii) and 75-5 wt.% of a polyisocyanate component (Dii), where the reaction is carried out in a molar ratio of 2:1:1 or 1:2:1, (partially) hydrolyzing (with 0.25-25 parts by weight of water) and silanizing 0.1-100 parts by weight of a stabilizing component (T), (c2) optionally partially or completely neutralizing the amino functional adduct with 0-75 parts by weight of an acid component (Uiv) or with 0-75 parts by weight of another neutralization component (W 1>), (c3) optionally partially or completely removing the liberated alcohol and/or the solvent components (S1) and/or (S2) before, during or after the reaction by distillation; (d) reacting 50-950 parts by weight of a mixture of 0.1-300 parts by weight of the component (A), optionally 0.004-120 parts by weight of the stabilization component (T), with 950-50 parts by weight of an activator component (X) containing 0.01-10 wt.% of an acid component (Uv), 0-99.999 wt.% of the component (Sii) and/or 0-99.99 wt.% of water, where the components (S1) and/or (S2), before, during or after the reaction are partially or completely removed by distillation, so that the amount of: the component (S1) is 0-50 parts by weight and the solvent (Sii) is 999.892-288.8 parts by weight, (e) optionally adding 0-50 parts by weight, respectively 0-60 parts by weight of a formulation component (Yi) and/or 0-50 parts by weight, respectively 0-60 parts by weight of a formulation component (Z) consisting of (e1) an amino silicone oil component (Eiv) of formula (HO-[Si(CH 3) 2-O] c-Si(CH 3)[(CH 2) 3NH(CH 2) 2NH 2]-O-[Si(CH 3) 2-O] c-H), R1aO-[Si(CH 3) 2-O] c-Si(CH 3)[(CH 2) 3NH(CH 2) 2NH 2]-O-[Si(CH 3) 2-O] c-R1a) or ((H 3CO) 2Si[(CH 2) 3NH(CH 2) 2NH 2]-[Si(CH 3) 2-O] c-Si[(CH 2) 3NH(CH 2) 2NH 2](OCH 3) 2), (e2) a low molecular silane compound (Ev) of formula (R 1>2>-Si(OR 1>) 3-xR 2>x), (e3) a hydrophilized aqueous silane component (Evi) consisting of (alcohol-free) aminosilane hydrolysate and/or (di/tri)amino/alkyl functional siloxane-co-oligomer and/or amino/vinyl functional siloxane-co-oligomer and/or epoxy functional siloxane-co-oligomer, or (e4) a (reactive) nanoparticle component (Yii); where all the reactions take place preferably in a molar ratio of 1:1.
