Abstract

The present invention relates to novel solventless reactive systems curable at room temperature, based on blocked polyisocyanates, primary amines, compounds with oxirane groups, and 2,3-dimethyl-3,4,5,6-tetrahydropyrimidine, and to processes for the preparation of these solventless reactive systems curable at room temperature.
