Abstract

The present invention relates to a process for the preparation of urea condensates and to their use. To prepare these urea condensates, a primary di and/or polyamine is reacted with urea, a secondary monoamine and if appropriate a polyalcohol at elevated temperatures in the presence or absence of catalysts, and the ammonia formed is separated off. These urea condensates are suitable as binder components in thermosetting surface coatings.
