Abstract
A thixotroping agent comprising a reaction product of a isocyanto-containing compound and an amine. The isocyanto-containing compound comprises at least one of Ia) at least one isocyanate with at least one diisocyanate structural unit that has an unsaturated/aromatic or non-aromatic ring structure with 5-10 ring atoms and two isocyanate groups that are bound to the ring structure; Ib) at least one oligomer of the isocyanate Ia) with 2 to 10 isocyanate units; and Ic) at least one partially blocked isocyanate Ia) and/or at least one partially blocked oligomer Ib).
