WÄSSRIGE DISPERSIONEN, ENTHALTEND POLYURETHAN, UND IHRE VERWENDUNG ZUR HERSTELLUNG VON FLÄCHIGEN SUBSTRATEN
摘要:
The invention relates to aqueous dispersions comprising (A) at least one polyurethane, (B) at least one compound of the general formula I a or I b (I a) (I b), wherein R1, R2 and R3 may be identical or different and are selected from A1-NCO and A1-NH-CO-X, wherein A1 is a spacer having 2 to 20 carbons atoms and X is selected as 0(AO)xR4, AO is C2-C4-alkyleneoxide, x is an integer in the range from 1 to 50, and R4 is selected from hydrogen and C1-C30-alkyl, (C) and at least one silicon compound with reactive groups.
