SILANE-MODIFIED POLYUREA COMPOUNDS BASED ON POLYISOCYANATES HAVING ISOCYANURATE AND ALLOPHANATE GROUPS

The invention relates to a polyurea compound that can be produced by reacting a polyisocyanate based on isophorone diisocyanate, which has isocyanurate and allophanate groups, with an amino silane according to general formula (I): R1 a(R1O)(3-a)Si(CH2)nNHCHR2CH2COOR3 (I), wherein the groups R1 are selected independently from one another from C1-C20-alkyl or C6-C20-aryl, a is a whole number between0 and 2, n is a whole number between 1 and 4, R2 is selected from H, C1-C20-alkyl, C6-C12-aryl and -COOR3, and R3 is a respective C1-C20-alkyl. The invention also relates to the use of the compound as a binder for producing coatings. 本发明涉及聚脲化合物，其能够通过基于异佛尔酮二异氰酸酯的具有异氰脲酸酯-和脲基甲酸酯基的多异氰酸酯与根据通式（I）：R(RO)Si(CH)NHCHRCHCOOR的氨基硅烷的反应来制备，其中基团R彼此独立地选自C-C-烷基或C-C-芳基，a是0-2的整数，n是1-4的整数，R选自H、C-C-烷基、C-C-芳基和-COOR，和R各自是C-C-烷基。本发明此外涉及该化合物作为粘料用于制备涂料的用途。
