The curable mixtures, processes for their preparation and their use

The invention relates to the use of blocked, partially blocked and unblocked polyisocyanates for thermally cross-linking primary and/or secondary carbamate group-containing compounds by the chemical reaction of the isocyanate groups with the carbamate groups. The invention further relates to curable mixtures of substances that contain, as the complementary reactive functional groups, primary and/or secondary carbamate groups and blocked and/or unblocked isocyanate groups that are effectively available for cross-linking the carbamate groups. The invention also relates to the use of the curable mixtures of substances as coating agents, adhesives and sealing compounds as well as to their use for producing the same.
