Abstract:
The invention relates to a process for preparing a solution which comprises urea urethanes and is effective as a thixotropic agent, which involves reacting at least two structurally different monohydroxy compounds with an excess of toluylene diisocyanate to form monoisocyanate adducts, removing the unreacted portion of the toluylene diisocyanate, and reacting the resultant monoisocyanate adducts with diamines in an aprotic solvent in the presence of a lithium salt to form urea urethanes. The invention also relates to the use of the solution to receive thixotropic coating compositions.
