Beschreibung
Zusammenfassung:	The invention relates to a two-component polyurethane dispersion adhesive comprising (I) at least one aqueous dispersion comprising an amorphous polyurethane-polyurea polymer, and (II) at least one hydrophilically modified polyisocyanate comprising a silane and a thioallophanate structure as cross-linking agent components. The invention also relates to the use of these two-component polyurethane dispersion adhesives for producing multilayer composites, in particular those consisting of synthetic substrates and substrates having metal surfaces, and to the composites obtainable using said adhesives. 本发明涉及双组分聚氨酯分散体胶粘剂，其包含(I)至少一种包含无定形聚氨酯-聚脲聚合物的水性分散体，和(II)至少一种含有硅烷和硫代脲基甲酸酯结构的亲水改性多异氰酸酯作为交联剂组分。本发明还涉及这些双组分聚氨酯分散体胶粘剂用于生产多层复合材料，尤其是由合成基底和具有金属表面的基底组成的那些多层复合材料的用途，以及涉及使用所述胶粘剂可获得的复合材料。
