Abstract: The invention relates to a polyurea compound, which can be produced by reacting a polyisocyanate with a dialkoxy amino silane according to general formula R1(R1O)2Si(CH2)mNHR2 and optionally also with a trialkoxy amino silane according to general formula (R1O)3Si(CH2)nNHR2 wherein the groups R1 are selected independently from one another from C1-C20-alkyl or C6-C20-aryl, n and m are each whole numbers between 1 and 4, the groups R2 are selected independently from one another from —H, C1-C2O-alkyl, C3-C12-cycloalkyl, and —CHR3CH2COOR4, the groups R3 are selected independently from one another from H, C1-C20-alkyl and —COOR4, and the groups R4 represent C1-C20-alkyl independently from one another. The invention also relates to the use of the compound as a binder for producing coatings.
