Abstract:
An aqueous surface coating agent comprising:A) an amine component consisting of at least one aminourethane A1), produced by the reaction of: a) at least one compound having at least one cyclic carbonate group; with b) at least one amine having at least one primary amine group, wherein the ratio of the number of cyclic carbonate groups to the number of primary amine groups is 1:10 to 1:1.1, and which may optionally be reacted with at least one hydrophilic water-dilutable epoxide compound A2), wherein the ratio of the number of all the amine hydrogen atoms in A1) to the epoxide groups in A2) is 2:1 to 20:1; and B) an epoxide component consisting of at least one urethane group-containing epoxide compound produced by the reaction of at least one epoxide compound c) with at least one polyisocyanate d), wherein the at least one polyisocyanate is used in an amount of 0.1 wt. % to 50 wt. %, with respect to the amount of epoxide compound (solids to solids).
