Liquid fluorine-containing compositions for surface treatment of mineral and non-mineral substrates

摘要

Liquid fluorine-containing compositions having a fluorine content of from 5 to 75% by weight based on the solid resin are described for the permanent surface treatment of porous and non-porous substrates which are obtainable by first a) preparing a perfluoroalkyl component (A), b) 5 to 500 parts by weight of the perfluoroalkyl component (A) from step a) before, during or after the reaction in 0 to 100 parts by weight of a solvent component (K) dissolves, c¶1¶) optionally the perfluoroalkyl component (A) from the stages a) or b) in the presence of 0 to 50 parts by weight of an aminoalkylalkoxysilane component (E) (i) and / or aminosilane component (E) (ii) with 1 to 50 parts by weight of water (partially) hydrolyzed or silanolisiert, c¶2¶) the amino-functional adduct with 5 to 50 parts by weight of an acid component (L) quaternized (direct neutralization), c¶3¶) optionally the released alcohol and / or the solvent component (K) removed, d¶1 ¶) the reaction product from step c) subsequently or simultaneously dissolved in 50 to 1000 parts by weight of water and oligomerized, d¶2¶) optionally the liberated alcohol and / or the solvent component (K), e) optionally during or after steps a) and / or b) and / or c) and / or d), in any desired manner, from 0 to 50 parts by weight of a formulation component (M) and / or from 0 to 50 parts by weight of a functionalization component (N) added and / or reacted with.
