Compositions containing coating durable novel compounds of aspartic amines.

摘要

A coating composition comprising a binder of a. a crosslinker polyisocyanate; b. a reactive component with the isocyanate groups having at least one compound having the following formula: ** (See formula) ** wherein R is a hydrocarbon radical selected from an alkyl group of C1 to C20 linear or branched, or cycloaliphatic C 5 to C 16 or a residue obtained by removing n amino groups from a polyether polyamine with m equal to 0 having a functionality of n and an average molecular weight of less than 600, wherein the amino groups are attached to primary carbon atoms and the ether groups are separated by at least two carbon atoms; m is 0 to 4, n is on average equal to 1 to 4; X and Y are independently O or NR 3; R3 is H, or an alkyl group of C1 to C20 linear or branched, a cycloaliphatic C5 to C16 group, or R 3 equals C 3 = O if s = 0, the compound is a cyclic imide; Z is selected from the group C1 to C20 linear or branched, a cycloaliphatic C5 to C16, or linear alkyl group or branched cycloaliphatic containing OH groups or Z comprises a fragment of the structure -CH 2 CHR 4 - R 5, with R 4 equal to H, or an alkyl group of C1 to C20 linear or branched, or cycloaliphatic group of C5 to C16 and R 5 equal to -CN or -C (= O) oR 6, with R 6 equal to H, or an alkyl group of C 1 to C 20 linear or branched, or a cycloaliphatic group C 5 to C 16; p and q are equal to 0 or 1, if p and q are equal to 1, the -NH-Z fragment can be bound to C1 or C2, and mixtures of compounds and isomers thereof; s is 0 or 1, with the proviso that s can only be 0 when p equals 1 and X = NR 3 wherein R 3 equals C 3 = O; R2 is H or is independently selected from an alkyl group of C 1 to C 20 linear or branched, or cycloaliphatic C 5 to C 16; R 1 is a hydrocarbon radical obtained by removing (q + r) hydrogen atoms of an alkyl group of C1 to C20 linear or branched, or a cycloaliphatic group C 5 to C 16; r is 0 to 4.
